jQuery function running multiple times despite input being disabled?

I'm having an issue where a function (and subsequent callback functions) continue to run after the first keypress, despite the fact that I'm specifically disabling the input and unbinding keypress. The weird thing is, these additional results only start appearing after a significant amount of time has passed (10+ seconds I would guess). You can see this error in action by going to http://isitsketch.com and mashing on the enter button while entering an address. The relevant code is this:
$('.location-form').keypress(function(event){
if (event.which == 13){
$(this).find('input').attr('disabled','disabled');
$(window).unbind("keypress")
console.log('search entered')
event.preventDefault();
userAddress = $("#input1").val()
address = userAddress.replace(/\s+/g, '+');
getMaps(address)
event.stopPropagation()
return false;
} else {
return true;
}
});
The function that displays the results is this:
function displayResults(sketchLevel, robberies, assaults, burglaries, thefts, weapons, topFiveArr) {
$('#newResults').append('<h4 id="feedback" style="color:white;text-align:center;">' + userAddress + '</h4>')
$("<h2 id='result-level'>Sketch Level: <span class='redText'>"+ sketchLevel +"</span></h2>").appendTo("#newResults")
$('<div id="indicator"><div id="bar"></div><div id="dial"></div></div>').appendTo("#newResults")
$('<a id="tryAgain" class="waves-effect waves-light btn" href="http://isitsketch.com">Enter a New Address</a>').appendTo("#newResults")
$('<p id="explanation">These results are based on NYC\'s OpenData information platform. The crimes have been weighted to reflect their severity. The resulting SketchLevel ranges from 0 (no crimes) to 2000+ (lots of severe crime activity).</p>').appendTo("#newResults")
$('#newResults').append('<h4 id="topFive">Can you beat these scores?:</h4><ul id="topList"></ul>')
for (i = 0; i < 5; i++){
var currentTopArea = topFiveArr[i]['area']
var currentTopRank = topFiveArr[i]['rank']
$('#topList').append('<li style="color:white; font-size:1em;">' + currentTopArea + ': ' +'<span id="rankText">' + currentTopRank + '</span>' +'</li>')
}
var audio = new Audio('sound/gunsound.mp3')
audio.play();
if(sketchLevel <= 400) {
$('#dial').addClass('sketchlevel1')
}
if(sketchLevel > 400 && sketchLevel <= 800) {
$('#dial').addClass('sketchlevel2')
}
if(sketchLevel > 800 && sketchLevel <= 1400){
$('#dial').addClass('sketchlevel3')
}
if(sketchLevel > 1500 && sketchLevel <= 2000) {
$('#dial').addClass('sketchlevel4')
}
if(sketchLevel > 2000) {
$('#dial').addClass('sketchlevel5')
}
}

Since the keypress event handler is bound to .location-form, you need to unbind it from that element, not window. So it should be:
$('.location-form').unbind("keypress");
Also, .off() is preferable to .unbind(), unless you need to be compatible with jQuery versions before 1.7.

I figured out how to stop it, although I still don't know why it was occurring in the first place. The fix was this:
var enabled = true;
displayResults(){
if (enabled) {
...the rest of the code here
enabled = false;
}
}
That said, it would be awesome if somebody else could figure out how/why it was getting around the input-disabled line and then continuing to post every 10 seconds or so. Just so weird.

How to add an event listener, remove it, and add it again?

I have a Chrome calendar app that displays the current month. I also have next Month and Previous month buttons that go the the next and previous month depending on what month is being displayed. However, I would only like the calendar to go as far as December of the current year and January of the current year, so after the user hits December/January, I remove the event handler. But, I need to add the event handler again when it is not December or January. How should I do this?
var count = 0;
var updated = setInterval(function() {
var v = document.getElementById("CalendarMonth").innerHTML;
updatedMonth = months.indexOf(v);
}, 1000);
document.getElementById("nextMonth").addEventListener("click", nxtMonth);
function nxtMonth()
{
count = count +1;
if(nextMonth == 11)
{
console.log("the year has ended!");
document.getElementById("nextMonth").removeEventListener("click", nxtMonth);
}
else
{
nextMonth = updated + count;
//ideally, this would work. But for some reason it does not
document.getElementById("nextMonth").addEventListener("click", nxtMonth);
}
document.getElementById("previousMonth").addEventListener("click", prevMonth);
function prevMonth()
{
count = count -1;
if(previousMonth == -1)
{
console.log("the year has just started!");
document.getElementById("previousMonth").removeEventListener("click", prevMonth);
}
else if(count==-1)
{
previousMonth =1;
}
else
{
previousMonth = updated + count;
document.getElementById("previousMonth").addEventListener("click", prevMonth);
}

Well I think a simpler approach would be to just not remove the click listener and instead just return immediately before incrementing/decrementing the current month.
So for instance the next month handler would be:
if (nextMonth == 11) {
return;
}
count++;

A simple and more elegant solution from the usability point of view would be to just add another event handler, one for each of the "next month" and "previous months" buttons to deactivate them when one of the limits are reached. This way, the browser will do the work for you (it won't allow the user to click them) and the user will also get the visual feedback that they have reached the limit.
function checkMonth(currentMonth)
{
if(currentMonth == 12){
document.getElementById("nextMonth").disabled = true;
} else {
document.getElementById("nextMonth").disabled = false;
}
if(currentMonth == 1){
document.getElementById("previousMonth").disabled = true;
} else {
document.getElementById("previousMonth").disabled = false;
}
}
Just call this function in your already existing event handlers for the two buttons.
I have not checked this function and maybe you can even optimise it a little bit, but this is the approach I would have.

jQuery on 'double click' event (dblclick for mobile)

I have the following jquery event handling function:
$('.target').on('dblclick', function() {
//respond to double click event
});
My issue is that this event handler doesn't work on touch devices (iPhone, iPad...). Can anyone recommend a reliable alternative to dblclick that works on touch devices and still allows comfortable double click use on full size devices?

I ended up building a custom double click function that will work on both mobile and desktop:
var touchtime = 0;
$(".target").on("click", function() {
if (touchtime == 0) {
// set first click
touchtime = new Date().getTime();
} else {
// compare first click to this click and see if they occurred within double click threshold
if (((new Date().getTime()) - touchtime) < 800) {
// double click occurred
alert("double clicked");
touchtime = 0;
} else {
// not a double click so set as a new first click
touchtime = new Date().getTime();
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div class="target">Double click me</div>
Alternatively, here is the JSfiddle Demo.

Add this to your index.html
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>
I found the mobile zoom function would throw off Jquery's dblclick. Basically it says your viewport wont change effectively shutting off the zoom. This works for me on my Nexus 5 running Chrome.

I know the question has been answered but thought it would be worth putting the solution I use all the time, cheers:
var doubleClicked = false;
$('.target').on('click', function() {
if (doubleClicked) {
//do what you want to do on double click here
}
doubleClicked = true;
setTimeout(() => {
doubleClicked = false;
}, 300);
});

You can bind multiple event listeners on the element and use jQuery's tap event for the touch devices.
$( ".target" ).on({
dbclick: function() {
//do stuff
}, touch: function() {
//do the same stuff
}
});

Thanks for the solution - the only thing I did was add a timeout so that they could be treated as separate events
var touchtime = 0;
var delay = 800;
var action = null;
$(".target").on("click", function() {
/*Double Click */
if((new Date().getTime() - touchtime) < delay){
clearTimeout(action)
alert('dbl');
touchtime=0;
}
/* Single Click */
else{
touchtime = new Date().getTime();
action = setTimeout(function(){
alert('single');
},delay);
}
}));
Although I haven't tested it, might also be worth adding the following to a header section of any HTML <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/> as per: To "user-scalable=no" or not to "user-scalable=no"

The marked answer of #JRulle seems to work only for a single object, if u have many instances with the same class they will be considered as a single object
see the exampleFiddle example
My solution seems to work in cases like that
var touchtime = 0;
$('.target').on('click', function() {
if (touchtime == 0) {
touchtime = new Date().getTime();
} else {
if (((new Date().getTime()) - touchtime) < 800) {
alert("double clicked");
touchtime = 0;
} else {
touchtime = 0;
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<p class="target">click me!</p>
<p class="target">then click me!</p>
click link

Multiple targets with own doubleclick counter. The accepted solution has 2 bugs, that are fixed here:
If you click on target and click outside and click on target again within 800 ms, then the doubleclick event fires.
If you have multiple targets, click on different targets within 800 ms, and the doubleclick event fires.
$(document).on("click", function(e)
{
var MAX_DELAY_IN_MS = 800;
var current_time = new Date();
var targets = $(".target");
if ((typeof last_target == "undefined") ||
(last_target == 0))
{
last_target = e.target;
last_click = current_time;
}
else
{
if ((last_target == e.target) &&
((targets.is(e.target) == true) ||
(targets.has(e.target).length !== 0)) &&
(current_time - last_click < MAX_DELAY_IN_MS))
{
alert("double clicked");
}
last_target = 0;
last_click = 0;
}
});
div{display:inline-block; width:30px; height:30px; margin:5px;}
.target{background-color:lime;}
.no_target{background-color:orange;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div class="target"></div>
<div class="target"></div>
<div class="no_target"></div>
<div class="target"></div>

Programmatically all of the answers given above are fine.
When you double click on mouse button it's just the mass off your finger involved,
so it can be fast...
On the other hand when tapping touch screen usually much larger physical mass is involved.
Larger mass means slower times .
So my approach is "click two times" instead of double click.
Means a global variable e.g var ClickCounter=0;
Inside the function scope
ClickCounter++;
Check if ClickCounter ==2.
Execute your Code.
Reset counter ClickCounter=0
else return false or execute another code

I have an improvement to the code above, that didn´t detect a doubleclick after a single click:
var touchtime = 0;
$(".target").on("click", function() {
if (((new Date().getTime()) - touchtime) < 500) {
alert("double clicked");
}
touchtime = new Date().getTime();
});
This code detects all doubleclicks. I also reduced the touchtime to 500ms (standard doubleclick-time).

The only way is to detect double touch yourselves. You can do it by persisting last touch event timestamp like below:
if (e.touches.length === 1) {
if (this.lastTouchEventTimeStamp) {
const timeInMillisecondsSinceLastTouch = e.timeStamp - this.lastTouchEventTimeStamp;
if (timeInMillisecondsSinceLastTouch > 80 && timeInMillisecondsSinceLastTouch < 400) {
// double tap will be detected here
this.lastTouchEventTimeStamp = undefined;
const dblClickEvent = new DragEvent('dblclick', {
view: window,
bubbles: true,
cancelable: true
});
e.target.dispatchEvent(dblClickEvent);
}
}
this.lastTouchEventTimeStamp = e.timeStamp;
}

Came across this thread and wanted to supply an updated answer.
function doubleClick(event, callback) {
var touchtime = $(event.target).data("touch-time");
if (touchtime == undefined || touchtime == 0) {
// set first click
$(event.target).data("touch-time", new Date().getTime());
} else {
// compare first click to this click and see if they occurred within double click threshold
if (((new Date().getTime()) - touchtime) < 800) {
// double click occurred
callback();
$(event.target).data("touch-time", 0);
} else {
// not a double click so set as a new first click
$(event.target).data("touch-time", new Date().getTime());
}
}
}
It can then be used as follows:
$(selector).click(function(event){
doubleClick(event, function(){
console.log("Hello World");
});
});
This uses the Data Attribute versus a global variable to get/set the Touch Time.
The standard dblclick should work in modern mobile browsers.

This is it... in CoffeeScript
onDblClick = -> "...your function to be fired..."
dbl_click = null
$(element).on 'mousedown', ->
onDblClick() if dbl_click
dbl_click = true
setTimeout () ->
dbl_click = false
, 250

You need to enter "return false" to the end of the function like below
var touchtime = 0;
$('.dbclickopen').click(function() {
if(touchtime == 0) {
//set first click
touchtime = new Date().getTime();
} else {
//compare first click to this click and see if they occurred within double click threshold
if(((new Date().getTime())-touchtime) < 800) {
//double click occurred
touchtime = 0;
window.location = this.href;
} else {
//not a double click so set as a new first click
touchtime = new Date().getTime();
}
}
return false;
});

how to add dbclick() on right click in jquery

Hi I want to have a dblclick() on the right click as the google maps have to zoom in and zoom out. Is there any way to do that. I have written the dblclick but now its working with only left click. Any pointers on how to do this. Here is my code
$("div#demo1").dblclick(function(e) {
//alert(e.getElementById());
if( (!$.browser.msie && e.button == 0) || ($.browser.msie && e.button == 1) ) {
alert("Left Mouse Button was clicked on demo1 div!");
$("div.window").animate({
'height':'+=20', 'width':'+=20'
},0,function(){
jsPlumb.repaintEverything();
jsPlumb.repaintEverything();
});
// Left mouse button was clicked (all browsers)
}
else if( (!$.browser.msie && e.button == 2) || ($.browser.msie && e.button == 3) ) {
alert("right click double");
}
});

There is another way you could detect a double right-click that does not involve fiddling with timers or keeping track of click counts manually. Using the .detail property of the event object in a mouseup or mousedown event. .detail holds the click count which will tell you how many clicks have happened recently. If .detail === 2 it was a double-click.
// suppress the right-click menu
$('#target').on('contextmenu', function (evt) {
evt.preventDefault();
});
$('#target').mouseup(function (evt) {
if (evt.which === 3) { // right-click
/* if you wanted to be less strict about what
counts as a double click you could use
evt.originalEvent.detail > 1 instead */
if (evt.originalEvent.detail === 2) {
$(this).text('Double right-click');
} else if (evt.originalEvent.detail === 1) {
$(this).text('Single right-click');
}
}
});
You might notice that I am using evt.originalEvent.detail to access the property instead of just .detail. This is because jQuery provides it's own version of the event object which does not include .detail, but you can access the original event object that the browser returned via .originalEvent. If you were using pure JavaScript instead of jQuery you would just use evt.detail.
Here's a working example.

There is no real way to do it, you can emulate it by taking the default timer for double clicks which IIRC is 300ms:
function makeDoubleRightClickHandler( handler ) {
var timeout = 0, clicked = false;
return function(e) {
e.preventDefault();
if( clicked ) {
clearTimeout(timeout);
clicked = false;
return handler.apply( this, arguments );
}
else {
clicked = true;
timeout = setTimeout( function() {
clicked = false;
}, 300 );
}
};
}
$(document).contextmenu( makeDoubleRightClickHandler( function(e) {
console.log("double right click" );
}));
http://jsfiddle.net/5kvFG/2/

Because the right-click has meaning to the user agent that is outside the purview of javascript (the context menu), you're going to have to do some dancing around.
First, you should disable the context menu on the target element:
document.getElementById('demo1').oncontextmenu = function() {
return false;
};
Now, when we right click, there won't be the context menu messing up the second click.
Next, understand that "double-click right" does not, generally speaking, exist. Even though you can bind the dblclick event, that isn't a generic event. "Double-click" is, by definition, double-clicking with the left mouse button.
So, we'll have to use the mousedown event, check to see how many times the right has been clicked, and react after two. I created a small helper function that keeps track of the click count and resets the state after a short time-frame.
var RightClick = {
'sensitivity':350,
'count':0,
'timer':false,
'active':function () {
this.count++;
this.timer = setTimeout(
this.endCountdown.bind(this),
this.sensitivity
);
},
'endCountdown': function () {
this.count = 0;
this.timer = false;
}
};
$("div#demo1").mousedown(function(e) {
if(e.which == 3) {
RightClick.active();
if (RightClick.count == 2)
alert("right click double");
}
});
Try it here: http://jsfiddle.net/94L7z/
You can adjust the sensitivity rate, allowing for shorter or longer double-clicks, depending on your preference.

"Javascript Madness: Mouse Events" on UnixPapa.com, an article showing some tests related to mouse events and the left/right buttons - http://unixpapa.com/js/mouse.html

The problem is the concept of double clicking is only relevant to the left mouse button as far as JS is concerned. So no matter how many time, and how fast you click the right mouse button, it just registers as a bunch of single clicks. So what to do?
Create a global variable to track click count
detect a single right-click, you already know how to do this it seems
set the global variable that the right-click was fired once
set a timeout, so if another right click doesn't come through in a
reasonable time to be considered a dblclick the global variable
resets to 0. I recommend 300 ms, it seems to be the most natural
each time a right-click registers check that variable, if it's more
than one, fire your double-right-click handler.
you may want to make that global variable an object so you can track which element
registered the right click and expire specific element right clicks
accordingly. This will allow you to ignore if they double click
while moving the mouse over various objects. I consider this
optional as the chain of events are unlikely for a user to follow,
but depending on your app may result in unexpected functionality.

It might be better to define a jQuery function with this (try it):
var precision = 400;
var lastClickTime = 0;
$(document).ready(function()
{
var div = $('#div');
$(div).bind("contextmenu", function(e)
{
return false;
});
$(div).mousedown(function(event)
{
if (event.which == 3)
{
var time = new Date().getTime();
if(time - lastClickTime <= precision)
{
// DOUBLE RIGHT CLICK
alert('double click');
}
lastClickTime = time;
}
});
});

How to differentiate single click event and double click event?

I have a single button in li with id "my_id". I attached two jQuery events with this element
1.
$("#my_id").click(function() {
alert('single click');
});
2.
$("#my_id").dblclick(function() {
alert('double click');
});
But every times it gives me the single click

Instead of utilizing more ad-hoc states and setTimeout, turns out there is a native property called detail that you can access from the event object!
element.onclick = event => {
if (event.detail === 1) {
// it was a single click
} else if (event.detail === 2) {
// it was a double click
}
};
Modern browsers and even IE-9 supports it :)
Source: https://developer.mozilla.org/en-US/docs/Web/API/UIEvent/detail

The behavior of the dblclick event is explained at Quirksmode.
The order of events for a dblclick is:
mousedown
mouseup
click
mousedown
mouseup
click
dblclick
The one exception to this rule is (of course) Internet Explorer with their custom order of:
mousedown
mouseup
click
mouseup
dblclick
As you can see, listening to both events together on the same element will result in extra calls to your click handler.

You need to use a timeout to check if there is an another click after the first click.
Here is the trick:
// Author: Jacek Becela
// Source: http://gist.github.com/399624
// License: MIT
jQuery.fn.single_double_click = function(single_click_callback, double_click_callback, timeout) {
return this.each(function(){
var clicks = 0, self = this;
jQuery(this).click(function(event){
clicks++;
if (clicks == 1) {
setTimeout(function(){
if(clicks == 1) {
single_click_callback.call(self, event);
} else {
double_click_callback.call(self, event);
}
clicks = 0;
}, timeout || 300);
}
});
});
}
Usage:
$("button").single_double_click(function () {
alert("Try double-clicking me!")
}, function () {
alert("Double click detected, I'm hiding")
$(this).hide()
})
<button>Click Me!</button>
EDIT:
As stated below, prefer using the native dblclick event: http://www.quirksmode.org/dom/events/click.html
Or the one provided by jQuery: http://api.jquery.com/dblclick/

The modern correct answer is a mix between the accepted answer and #kyw 's solution.
You need a timeout to prevent that first single click and the event.detail check to prevent the second click.
const button = document.getElementById('button')
let timer
button.addEventListener('click', event => {
if (event.detail === 1) {
timer = setTimeout(() => {
console.log('click')
}, 200)
}
})
button.addEventListener('dblclick', event => {
clearTimeout(timer)
console.log('dblclick')
})
<button id="button">Click me</button>

A simple function. No jquery or other framework is required. Pass your functions as parameters
<div onclick="doubleclick(this, function(){alert('single')}, function(){alert('double')})">click me</div>
<script>
function doubleclick(el, onsingle, ondouble) {
if (el.getAttribute("data-dblclick") == null) {
el.setAttribute("data-dblclick", 1);
setTimeout(function () {
if (el.getAttribute("data-dblclick") == 1) {
onsingle();
}
el.removeAttribute("data-dblclick");
}, 300);
} else {
el.removeAttribute("data-dblclick");
ondouble();
}
}
</script>

I'm afraid that the behaviour is browser dependent:
It is inadvisable to bind handlers to
both the click and dblclick events for
the same element. The sequence of
events triggered varies from browser
to browser, with some receiving two
click events before the dblclick and
others only one. Double-click
sensitivity (maximum time between
clicks that is detected as a double
click) can vary by operating system
and browser, and is often
user-configurable.
http://api.jquery.com/dblclick/
Running your code in Firefox, the alert() in the click() handler prevents you from clicking a second time. If you remove such alert, you get both events.

Well in order to double click (click twice) you must first click once. The click() handler fires on your first click, and since the alert pops up, you don't have a chance to make the second click to fire the dblclick() handler.
Change your handlers to do something other than an alert() and you'll see the behaviour. (perhaps change the background color of the element):
$("#my_id").click(function() {
$(this).css('backgroundColor', 'red')
});
$("#my_id").dblclick(function() {
$(this).css('backgroundColor', 'green')
});

This answer is made obsolete through time, check #kyw's solution.
I created a solution inspired by the gist posted by #AdrienSchuler. Use this solution only when you want to bind a single click AND a double click to an element. Otherwise I recommend using the native click and dblclick listeners.
These are the differences:
Vanillajs, No dependencies
Don't wait on the setTimeout to handle the click or doubleclick handler
When double clicking it first fires the click handler, then the doubleclick handler
Javascript:
function makeDoubleClick(doubleClickCallback, singleClickCallback) {
var clicks = 0, timeout;
return function() {
clicks++;
if (clicks == 1) {
singleClickCallback && singleClickCallback.apply(this, arguments);
timeout = setTimeout(function() { clicks = 0; }, 400);
} else {
timeout && clearTimeout(timeout);
doubleClickCallback && doubleClickCallback.apply(this, arguments);
clicks = 0;
}
};
}
Usage:
var singleClick = function(){ console.log('single click') };
var doubleClick = function(){ console.log('double click') };
element.addEventListener('click', makeDoubleClick(doubleClick, singleClick));
Below is the usage in a jsfiddle, the jQuery button is the behavior of the accepted answer.
jsfiddle

Another simple Vanilla solution based on the A1rPun answer (see his fiddle for the jQuery solution, and both are in this one).
It seems that to NOT trigger a single-click handler when the user double-clicks, the single-click handler is necessarily triggered after a delay...
var single = function(e){console.log('single')},
double = function(e){console.log('double')};
var makeDoubleClick = function(e) {
var clicks = 0,
timeout;
return function (e) {
clicks++;
if (clicks == 1) {
timeout = setTimeout(function () {
single(e);
clicks = 0;
}, 250);
} else {
clearTimeout(timeout);
double(e);
clicks = 0;
}
};
}
document.getElementById('btnVanilla').addEventListener('click', makeDoubleClick(), false);

How to differentiate between single clicks and double clicks on one and the same element?
If you don't need to mix them, you can rely on click and dblclick and each will do the job just fine.
A problem arises when trying to mix them: a dblclick event will actually trigger a click event as well, so you need to determine whether a single click is a "stand-alone" single click, or part of a double click.
In addition: you shouldn't use both click and dblclick on one and the same element:
It is inadvisable to bind handlers to both the click and dblclick events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two click events before the dblclick and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable.
Source: https://api.jquery.com/dblclick/
Now on to the good news:
You can use the event's detail property to detect the number of clicks related to the event. This makes double clicks inside of click fairly easy to detect.
The problem remains of detecting single clicks and whether or not they're part of a double click. For that, we're back to using a timer and setTimeout.
Wrapping it all together, with use of a data attribute (to avoid a global variable) and without the need to count clicks ourselves, we get:
HTML:
<div class="clickit" style="font-size: 200%; margin: 2em; padding: 0.25em; background: orange;">Double click me</div>
<div id="log" style="background: #efefef;"></div>
JavaScript:
<script>
var clickTimeoutID;
$( document ).ready(function() {
$( '.clickit' ).click( function( event ) {
if ( event.originalEvent.detail === 1 ) {
$( '#log' ).append( '(Event:) Single click event received.<br>' );
/** Is this a true single click or it it a single click that's part of a double click?
* The only way to find out is to wait it for either a specific amount of time or the `dblclick` event.
**/
clickTimeoutID = window.setTimeout(
function() {
$( '#log' ).append( 'USER BEHAVIOR: Single click detected.<br><br>' );
},
500 // how much time users have to perform the second click in a double click -- see accessibility note below.
);
} else if ( event.originalEvent.detail === 2 ) {
$( '#log' ).append( '(Event:) Double click event received.<br>' );
$( '#log' ).append( 'USER BEHAVIOR: Double click detected.<br>' );
window.clearTimeout( clickTimeoutID ); // it's a dblclick, so cancel the single click behavior.
} // triple, quadruple, etc. clicks are ignored.
});
});
</script>

Notes about accessibility and double click speeds:
As Wikipedia puts it "The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized."
No way of detecting the system's double-click speed in the browser.
Seems the default is 500 ms and the range 100-900mms on Windows (source)
Think of people with disabilities who set, in their OS settings, the double click speed to its slowest.
If the system double click speed is slower than our default 500 ms above, both the single- and double-click behaviors will be triggered.
Either don't use rely on combined single and double click on one and the same item.
Or: add a setting in the options to have the ability to increase the value.
It took a while to find a satisfying solution, I hope this helps!

Here's an alternative of jeum's code for an arbitrary number of events:
var multiClickHandler = function (handlers, delay) {
var clicks = 0, timeout, delay = delay || 250;
return function (e) {
clicks++;
clearTimeout(timeout);
timeout = setTimeout(function () {
if(handlers[clicks]) handlers[clicks](e);
clicks = 0;
}, delay);
};
}
cy.on('click', 'node', multiClickHandler({
1: function(e){console.log('single clicked ', e.cyTarget.id())},
2: function(e){console.log('double clicked ', e.cyTarget.id())},
3: function(e){console.log('triple clicked ', e.cyTarget.id())},
4: function(e){console.log('quadro clicked ', e.cyTarget.id())},
// ...
}, 300));
Needed this for a cytoscape.js app.

Use the excellent jQuery Sparkle plugin. The plugin gives you the option to detect first and last click. You can use it to differentiate between click and dblclick by detecting if another click was followed by the first click.
Check it out at http://balupton.com/sandbox/jquery-sparkle/demo/

I wrote a simple jQuery plugin that lets you use a custom 'singleclick' event to differentiate a single-click from a double-click:
https://github.com/omriyariv/jquery-singleclick
$('#someDiv').on('singleclick', function(e) {
// The event will be fired with a small delay.
console.log('This is certainly a single-click');
}

I like to avoid jquery (and other 90-140k libs), and as noted browsers handle onclick first, so here is what I did on a website I created (this example also covers getting a clicked location local x y )
clicksNow-0; //global js, owell
function notify2(e, right) { // called from onclick= and oncontextmenu= (rc)
var x,y,xx,yy;
var ele = document.getElementById('wrap');
// offset fixed parent for local win x y
var xxx= ele.offsetLeft;
var yyy= ele.offsetTop;
//NScape
if (document.layers || document.getElementById&&!document.all) {
xx= e.pageX;
yy= e.pageY;
} else {
xx= e.clientX;
yy= e.clientY;
}
x=xx-xxx;
y=yy-yyy;
clicksNow++;
// 200 (2/10ths a sec) is about a low as i seem to be able to go
setTimeout( "processClick( " + right + " , " + x + " , " + y + ")", 200);
}
function processClick(right, x, y) {
if (clicksNow==0) return; // already processed as dblclick
if (clicksNow==2) alert('dbl');
clicksNow=0;
... handle, etc ...
}
hope that helps

Based on Adrien Schuler (thank you so much!!!) answer, for Datatables.net and for many uses, here is a modification:
Function
/**
* For handle click and single click in child's objects
* #param {any} selector Parents selector, like 'tr'
* #param {any} single_click_callback Callback for single click
* #param {any} double_click_callback Callback for dblclick
* #param {any} timeout Timeout, optional, 300 by default
*/
jQuery.fn.single_double_click = function (selector, single_click_callback, double_click_callback, timeout) {
return this.each(function () {
let clicks = 0;
jQuery(this).on('click', selector, function (event) {
let self = this;
clicks++;
if (clicks == 1) {
setTimeout(function () {
if (clicks == 1) {
single_click_callback.call(self, event);
} else {
double_click_callback.call(self, event);
}
clicks = 0;
}, timeout || 300);
}
});
});
}
Use
$("#MyTableId").single_double_click('tr',
function () { // Click
let row = MyTable.row(this);
let id = row.id();
let data = row.data();
console.log("Click in "+id+" "+data);
},
function () { // DBLClick
let row = MyTable.row(this);
let id = row.id();
let data = row.data();
console.log("DBLClick in "+id+" "+data);
}
);

let clickTimes = 0;
let timer = null;
roundBox.click = function (e) {
clearTimeout(timer);
timer = setTimeout(() => { // 单击事件
console.log("single click");
}, 600);
clickTimes++;
if (clickTimes == 2) { // 双击
clearTimeout(timer);
clickTimes = 0;
console.log("double click");
toggleExpanded(id);
}
}

this worked for me–
var clicked=0;
function chkBtnClcked(evnt) {
clicked++;
// wait to see if dblclick
if (clicked===1) {
setTimeout(function() {
clicked=0;
.
.
}, 300); // test for another click within 300ms
}
if (clicked===2) {
stopTimer=setInterval(function() {
clicked=0;
.
.
}, 30*1000); // refresh every 30 seconds
}
}
usage–
<div id="cloneimages" style="position: fixed;" onclick="chkBtnClcked(evnt)" title="Click for next pic; double-click for slide show"></div>

Just posting the native HTML answer just in case the need is to be easy and HTML.
<p ondblclick="myFunction()" id = 'id'>Double-click me</p>
This of course has native Jquery options. ie... $('#id').attr('ondblclick',function(){...}) or, as stated previously, $('#id').dblclick(function(){...});

I know this is old, but below is a JS only example of a basic loop counter with a single timer to determine a single vs double click. Hopefully this helps someone.
var count = 0;
var ele = document.getElementById("my_id");
ele.addEventListener('click', handleSingleDoubleClick, false);
function handleSingleDoubleClick()
{
if(!count) setTimeout(TimerFcn, 400); // 400 ms click delay
count += 1;
}
function TimerFcn()
{
if(count > 1) console.log('you double clicked!')
else console.log('you single clicked')
count = 0;
}

Try this code
let click = 0;
element.onclick = (event) => {
click++;
console.log(click);
setTimeout(() => {
click = 0;
}, 300);
if (click === 2) {
console.log("double Click");
click = 0;
console.log(click);
}
};

If you want to distinguish between a single and double click, the event handler of the single click has to wait until it is proven, that the single click is not the beginning of a double click. This makes single clicks lagging. The example shows this.
var distinguish = (() => {
var target = null;
var timeout = null;
return (element, action) => {
element.addEventListener ('click', e => {
if (e.target === target) {
clearTimeout (timeout);
target = null;
timeout = null;
action ('double');
} else {
target = e.target;
timeout = setTimeout (() => {
target = null;
timeout = null;
action ('single');
}, 500);
}
});
};
})();
var button = document.getElementById ('button');
distinguish (button, kind => console.log (kind + ' click'));
<input id="button" type="button" value="click">

Pure JS, to truly differentiate single- vs double-click, (e.g. not triggering both at the same time). I'm using this combination of the native event.detail and a custom delay, to prevent the single-click from firing, if it gets cancelled by a double-click.
This approach is also very performance friendly, as it doesn't start a new timer every time we click in quick succession.
The only minor thing (as with some of the other solutions too), is that it may still fire both events, if the user double-clicks very very slowly. This can be prevented by highering the delay, but that would make single-clicking feel even more laggy.
Also there is a lot of differences in the suggested answers as to how they handle quick multi-clicking. So to make things clear, here is what happens in every consecutive click with this approach:
triggers a slightly delayed single-click, if it isn't cancelled by a doubleclick
triggers double-click
nothing
triggers double-click
nothing
...(every 2nd click is a doubleclick, which feels very natural)
I included a snippet so you can test it for yourself.
document.querySelector('button').addEventListener('click', single_or_double);
let isSingleClick; // flag to allow or cancel single clicks
function single_or_double(){
if (isSingleClick = event.detail == 1){ //check for a singleclick and store flag globally at the same time
setTimeout(() => {
if(isSingleClick){ //check if the flag is still set after the delay
console.log("single");
}
}, 200); // singleclick delay in milliseconds
}
else if (event.detail == 2) {
console.log("double");
}
}
<button>Single OR Double-Click</button>
