I've toggled click event to a node and I want to toggle a dbclick event to it as well. However it only triggers the click event when I dbclick on it.
So How do I set both events at the same time?
You have to do your "own" doubleclick detection
Something like that could work:
var clickedOnce = false;
var timer;
$("#test").bind("click", function(){
if (clickedOnce) {
run_on_double_click();
} else {
timer = setTimeout(function() {
run_on_simple_click(parameter);
}, 150);
clickedOnce = true;
}
});
function run_on_simple_click(parameter) {
alert(parameter);
alert("simpleclick");
clickedOnce = false;
}
function run_on_double_click() {
clickedOnce = false;
clearTimeout(timer);
alert("doubleclick");
}
Here is a working JSFiddle
For more information about what delay you should use for your timer, have a look here : How to use both onclick and ondblclick on an element?
$("#test-id").bind("click dblclick", function(){alert("hello")});
Works for both click and dblclick
EDIT --
I think its not possible. I was trying something like this.
$("#test").bind({
dblclick: function(){alert("Hii")},
mousedown: function(){alert("hello")}
});
But its not possible to reach double click without going through single click. I tried mouse down but it does not give any solution.
I pretty much used the same logic as Jeremy D.
However, in my case, it was more neat to solve this thing with anonymous functions, and a little slower double click timeout:
dblclick_timer = false
.on("click", function(d) {
// if double click timer is active, this click is the double click
if ( dblclick_timer )
{
clearTimeout(dblclick_timer)
dblclick_timer = false
// double click code code comes here
console.log("double click fired")
}
// otherwise, what to do after single click (double click has timed out)
else dblclick_timer = setTimeout( function(){
dblclick_timer = false
// single click code code comes here
console.log("single click fired")
}, 250)
})
you need to track double click and if its not a double click perform click action.
Try this
<p id="demo"></p>
<button id='btn'>Click and DoubleClick</button>
<script>
var doubleclick =false;
var clicktimeoutid = 0;
var dblclicktimeoutid = 0;
var clickcheck = function(e){
if(!clicktimeoutid)
clicktimeoutid = setTimeout(function(){
if(!doubleclick)
performclick(e);
clicktimeoutid =0;
},300);
}
var performclick =function(e){
document.getElementById("demo").innerHTML += 'click';
}
var performdblclick = function(e)
{
doubleclick = true;
document.getElementById("demo").innerHTML += 'dblclick';
dblclicktimeoutid = setTimeout(function(){doubleclick = false},800);
};
document.getElementById("btn").ondblclick = performdblclick;
document.getElementById("btn").onclick=clickcheck;
</script>
a slightly different approach - The actual click comparison happens later in the timeOut function, after a preset interval... till then we simply keep tab on the flags.
& with some simple modifications (click-counter instead of flags) it can also be extended to any number of rapid successive clicks (triple click, et al), limited by practicality.
var clicked = false,
dblClicked = false,
clickTimer;
function onClick(param){
console.log('Node clicked. param - ',param);
};
function onDoubleClick(param){
console.log('Node Double clicked. param - ',param);
};
function clickCheck(param){
if (!clicked){
clicked = true;
clickTimer = setTimeout(function(){
if(dblClicked){
onDoubleClick(param);
}
else if(clicked){
onClick(param);
}
clicked = false;
dblClicked = false;
clearTimeout(clickTimer);
},150);
} else {
dblClicked = true;
}
};
I have a mobile based web application. Currently I am encountering an issue when ajax calls are being made. The wait spinner which is enclosed in a div can be clicked through on the ipad device. The javascript event being triggered is touchstart. Is there anyway to prevent this event from going through normal processing?
Tried to call the following, however it did not work.
Disable
document.ontouchstart = function(e){ e.preventDefault(); }
Enable
document.ontouchstart = function(e){ return true; }
How touchstart is handled
$(document).on('touchstart', function (eventObj) {
//toggle for view-icon
if (eventObj.target.id == "view-icon") {
$("#view-dropdown").toggle();
} else if ($(eventObj.target).hasClass("view-dropdown")) {
$("#view-dropdown").show();
} else {
$("#view-dropdown").hide();
}
});
As user3032973 commented, you can use a touchLocked variable, which is working perfectly.
I have used it in combination with the Cordova Keyboard-Plugin. Scrolling will be disabled the time the keyboard is shown up and reenabled the time the keyboard is hiding:
var touchLocked = false;
Keyboard.onshowing = function () {
touchLocked = true;
};
Keyboard.onhiding = function () {
touchLocked = false;
};
document.ontouchstart = function(e){
if(touchLocked){
e.preventDefault();
}
};
Is there something in jquery that would allow me to differentiate between behavior on double click and single click?
When I bind both to same element only the single click gets executed.
Is there a way that wait for some time before execution of the single click to see if the user clicks again or not?
Thanks :)
I found that John Strickler's answer did not quite do what I was expecting. Once the alert is triggered by a second click within the two-second window, every subsequent click triggers another alert until you wait two seconds before clicking again. So with John's code, a triple click acts as two double clicks where I would expect it to act like a double click followed by a single click.
I have reworked his solution to function in this way and to flow in a way my mind can better comprehend. I dropped the delay down from 2000 to 700 to better simulate what I would feel to be a normal sensitivity. Here's the fiddle: http://jsfiddle.net/KpCwN/4/.
Thanks for the foundation, John. I hope this alternate version is useful to others.
var DELAY = 700, clicks = 0, timer = null;
$(function(){
$("a").on("click", function(e){
clicks++; //count clicks
if(clicks === 1) {
timer = setTimeout(function() {
alert("Single Click"); //perform single-click action
clicks = 0; //after action performed, reset counter
}, DELAY);
} else {
clearTimeout(timer); //prevent single-click action
alert("Double Click"); //perform double-click action
clicks = 0; //after action performed, reset counter
}
})
.on("dblclick", function(e){
e.preventDefault(); //cancel system double-click event
});
});
The solution given from "Nott Responding" seems to fire both events, click and dblclick when doubleclicked. However I think it points in the right direction.
I did a small change, this is the result :
$("#clickMe").click(function (e) {
var $this = $(this);
if ($this.hasClass('clicked')){
$this.removeClass('clicked');
alert("Double click");
//here is your code for double click
}else{
$this.addClass('clicked');
setTimeout(function() {
if ($this.hasClass('clicked')){
$this.removeClass('clicked');
alert("Just one click!");
//your code for single click
}
}, 500);
}
});
Try it
http://jsfiddle.net/calterras/xmmo3esg/
Sure, bind two handlers, one to click and the other to dblclick. Create a variable that increments on every click. then resets after a set delay. Inside the setTimeout function you can do something...
var DELAY = 2000,
clicks = 0,
timer = null;
$('a').bind({
click: function(e) {
clearTimeout(timer);
timer = setTimeout(function() {
clicks = 0;
}, DELAY);
if(clicks === 1) {
alert(clicks);
//do something here
clicks = 0;
}
//Increment clicks
clicks++;
},
dblclick: function(e) {
e.preventDefault(); //don't do anything
}
});
You could probably write your own custom implementation of click/dblclick to have it wait for an extra click. I don't see anything in the core jQuery functions that would help you achieve this.
Quote from .dblclick() at the jQuery site
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.
Look at the following code
$("#clickMe").click(function (e) {
var $this = $(this);
if ($this.hasClass('clicked')){
alert("Double click");
//here is your code for double click
return;
}else{
$this.addClass('clicked');
//your code for single click
setTimeout(function() {
$this.removeClass('clicked'); },500);
}//end of else
});
Demo goes here http://jsfiddle.net/cB484/
I've written a jQuery plugin that allow also to delegate the click and dblclick events
// jQuery plugin to bind both single and double click to objects
// parameter 'delegateSelector' is optional and allow to delegate the events
// parameter 'dblclickWait' is optional default is 300
(function($) {
$.fn.multipleClicks = function(delegateSelector, clickFun, dblclickFun, dblclickWait) {
var obj;
if (typeof(delegateSelector)==='function' && typeof(clickFun)==='function') {
dblclickWait = dblclickFun; dblclickFun = clickFun; clickFun = delegateSelector; delegateSelector = null; // If 'delegateSelector' is missing reorder arguments
} else if (!(typeof(delegateSelector)==='string' && typeof(clickFun)==='function' && typeof(dblclickFun)==='function')) {
return false;
}
return $(this).each(function() {
$(this).on('click', delegateSelector, function(event) {
var self = this;
clicks = ($(self).data('clicks') || 0)+1;
$(self).data('clicks', clicks);
if (clicks == 1) {
setTimeout(function(){
if ($(self).data('clicks') == 1) {
clickFun.call(self, event); // Single click action
} else {
dblclickFun.call(self, event); // Double click action
}
$(self).data('clicks', 0);
}, dblclickWait || 300);
}
});
});
};
})(jQuery);
This solution works for me
var DELAY = 250, clicks = 0, timer = null;
$(".fc-event").click(function(e) {
if (timer == null) {
timer = setTimeout(function() {
clicks = 0;
timer = null;
// single click code
}, DELAY);
}
if(clicks === 1) {
clearTimeout(timer);
timer = null;
clicks = -1;
// double click code
}
clicks++;
});
i am implementing this simple solution , http://jsfiddle.net/533135/VHkLR/5/
html code
<p>Click on this paragraph.</p>
<b> </b>
script code
var dbclick=false;
$("p").click(function(){
setTimeout(function(){
if(dbclick ==false){
$("b").html("clicked")
}
},200)
}).dblclick(function(){
dbclick = true
$("b").html("dbclicked")
setTimeout(function(){
dbclick = false
},300)
});
its not much laggy
var singleClickTimer = 0; //define a var to hold timer event in parent scope
jqueryElem.click(function(e){ //using jquery click handler
if (e.detail == 1) { //ensure this is the first click
singleClickTimer = setTimeout(function(){ //create a timer
alert('single'); //run your single click code
},250); //250 or 1/4th second is about right
}
});
jqueryElem.dblclick(function(e){ //using jquery dblclick handler
clearTimeout(singleClickTimer); //cancel the single click
alert('double'); //run your double click code
});
I made some changes to the above answers here which still works great: http://jsfiddle.net/arondraper/R8cDR/
Below is my simple approach to the issue.
JQuery function:
jQuery.fn.trackClicks = function () {
if ($(this).attr("data-clicks") === undefined) $(this).attr("data-clicks", 0);
var timer;
$(this).click(function () {
$(this).attr("data-clicks", parseInt($(this).attr("data-clicks")) + 1);
if (timer) clearTimeout(timer);
var item = $(this);
timer = setTimeout(function() {
item.attr("data-clicks", 0);
}, 1000);
});
}
Implementation:
$(function () {
$("a").trackClicks();
$("a").click(function () {
if ($(this).attr("data-clicks") === "2") {
// Double clicked
}
});
});
Inspect the clicked element in Firefox/Chrome to see data-clicks go up and down as you click, adjust time (1000) to suit.
(function($){
$.click2 = function (elm, o){
this.ao = o;
var DELAY = 700, clicks = 0;
var timer = null;
var self = this;
$(elm).on('click', function(e){
clicks++;
if(clicks === 1){
timer = setTimeout(function(){
self.ao.click(e);
}, DELAY);
} else {
clearTimeout(timer);
self.ao.dblclick(e);
}
}).on('dblclick', function(e){
e.preventDefault();
});
};
$.click2.defaults = { click: function(e){}, dblclick: function(e){} };
$.fn.click2 = function(o){
o = $.extend({},$.click2.defaults, o);
this.each(function(){ new $.click2(this, o); });
return this;
};
})(jQuery);
And finally we use as.
$("a").click2({
click : function(e){
var cid = $(this).data('cid');
console.log("Click : "+cid);
},
dblclick : function(e){
var cid = $(this).data('cid');
console.log("Double Click : "+cid);
}
});
Same as the above answer but allows for triple click. (Delay 500)
http://jsfiddle.net/luenwarneke/rV78Y/1/
var DELAY = 500,
clicks = 0,
timer = null;
$(document).ready(function() {
$("a")
.on("click", function(e){
clicks++; //count clicks
timer = setTimeout(function() {
if(clicks === 1) {
alert('Single Click'); //perform single-click action
} else if(clicks === 2) {
alert('Double Click'); //perform single-click action
} else if(clicks >= 3) {
alert('Triple Click'); //perform Triple-click action
}
clearTimeout(timer);
clicks = 0; //after action performed, reset counter
}, DELAY);
})
.on("dblclick", function(e){
e.preventDefault(); //cancel system double-click event
});
});
This is a method you can do using the basic JavaScript, which is works for me:
var v_Result;
function OneClick() {
v_Result = false;
window.setTimeout(OneClick_Nei, 500)
function OneClick_Nei() {
if (v_Result != false) return;
alert("single click");
}
}
function TwoClick() {
v_Result = true;
alert("double click");
}

I am trying to implement one event for a short press and a different for a long press. The short press is just doing the default action. The long press works, but also does the default action still. What am I missing?
HTML
<"Label for my Link"
Javascript
$(document).ready(function(){
$('.recordlongpress').each(function() {
var timeout, longtouch;
$(this).mousedown(function() {
timeout = setTimeout(function() {
longtouch = true;
}, 1000);
}).mouseup(function(e) {
if (longtouch) {
e.preventDefault();
$('#popupPanel').popup("open");
return false;
} else {
return;
}
longtouch = false;
clearTimeout(timeout);
});
});
});
I followed the jQuery documentation and was under the impress "preventDefault" should stop the short press default action. Any examples I have found online do not seem to be exactly my situation. I appreciate you taking the time to read this. Thank you for any input.
You're returning from your "mouseup" handler before clearing the timeout and setting "longtouch" to false.
Try:
}).mouseup(function(e) {
var returnval;
if (longtouch) {
e.preventDefault();
$('#popupPanel').popup("open");
returnval = false;
}
longtouch = false;
clearTimeout(timeout);
return returnVal;
});
I'd also clear "longtouch" in the "mousedown" handler. That said, I wouldn't do this with mouse events. I'd use "touchstart" and "touchend". On touch screen devices, "mouse" events are simulated from touch events, and there's a distinct delay involved. (You may also want to detect whether the finger moved during the touch period.)
jsFiddle Demo
In your code these lines are unreachable
longtouch = false;
clearTimeout(timeout);
JS:
$('.recordlongpress').each(function () {
var timeout, longtouch = false;
$(this).mousedown(function () {
timeout = setTimeout(function () {
longtouch = true;
}, 1000);
e.preventDefault();
}).mouseup(function (e) {
clearTimeout(timeout);
if (longtouch == true) {
longtouch = false;
$('body').append("long press" + longtouch);
return false;
} else {
return;
}
});
});
#Pointy lead me towards a working solution for clicking events.
$(document).ready(function(){
$('.recordlongpress').bind('tap', function(event) {
return;
});
$('.recordlongpress').bind('taphold', function(event) {
$('#popupPanel').popup("open");
});
});
Something still needs to be added because upon a long press on my mobile device, the default options screen with the four options; open, save link, copy link URL and select text still pops up as well. I will add on the fix for that once I find it.
I have window.onbeforeunload triggering properly. It's displaying a confirmation box to ensure the user knows they are navigating (closing) the window and that any unsaved work will be erased.
I have a unique situation where I don't want this to trigger if a user navigates away from the page by clicking a link, but I can't figure out how to detect if a link has been clicked inside the function to halt the function. This is what I have for code:
window.onbeforeunload = function() {
var message = 'You are leaving the page.';
/* If this is Firefox */
if(/Firefox[\/\s](\d+)/.test(navigator.userAgent) && new Number(RegExp.$1) >= 4) {
if(confirm(message)) {
history.go();
}
else {
window.setTimeout(function() {
window.stop();
}, 1);
}
}
/* Everything else */
else {
return message;
}
}
You're looking for deferred event handling. I'll explain using jQuery, as it is less code:
window._link_was_clicked = false;
window.onbeforeunload = function(event) {
if (window._link_was_clicked) {
return; // abort beforeunload
}
// your event handling
};
jQuery(document).on('click', 'a', function(event) {
window._link_was_clicked = true;
});
a (very) poor man's implementation without jQuery's convenient delegation handling could look like:
document.addEventListener("click", function(event) {
if (this.nodeName.toLowerCase() === 'a') {
window._link_was_clicked = true;
}
}, true);
this allows all links on your page to leave without invoking the beforeunload handler. I'm sure you can figure out how to customize this, should you only want to allow this for a specific set of links (your question wasn't particularly clear on that).
var link_was_clicked = false;
document.addEventListener("click", function(e) {
if (e.target.nodeName.toLowerCase() === 'a') {
link_was_clicked = true;
}
}, true);
window.onbeforeunload = function() {
if(link_was_clicked) {
link_was_clicked = false;
return;
}
//other code here
}
You can differ between a link unload or a reload/user entering a different address unload s by using a timer. This way you know the beforeunload was triggered directly after the link click.
Example using jQuery:
$('a').on('click', function(){
window.last_clicked_time = new Date().getTime();
window.last_clicked = $(this);
});
$(window).bind('beforeunload', function() {
var time_now = new Date().getTime();
var link_clicked = window.last_clicked != undefined;
var within_click_offset = (time_now - window.last_clicked_time) < 100;
if (link_clicked && within_click_offset) {
return 'You clicked a link to '+window.last_clicked[0].href+'!';
} else {
return 'You are leaving or reloading the page!';
}
});
