var bar = $('.div_layer_Class');
$('a.second_line').click(function() {
$(this).unbind('mouseout');
}).mouseover(function() {
bar.css('display','inline');
}).mouseout(function() {
bar.css('display','none');
});
now the issue with 'onBodyclick' when i click anywhere on body again i want to invoke mouseoutevent something like this
$('body').click(function() {
bar.css('display','none');
event.preventDefault();
});
when I do this it overlaps $('a.second_line').click(function() event. any idea how I can Achieve this.

In addition to e.stopPropagation(),
you can do 2 things:
make a variable to reference the mouseout event handler so you can re-bind it whenever the user clicks elsewhere to the body.
or
A variable to store to whether a.second_line is focused or not. Something like
var focused = false;
You code now will be:
var bar = $('.div_layer_Class');
var focused = false;
$('a.second_line').click(function(e) {
focused = true;
e.stopPropagation();
}).mouseover(function() {
bar.css('display','inline');
}).mouseout(function() {
if (!focused)
bar.css('display','none');
});
$(document).click(function(e){
bar.css('display','none');
focused = false;
});
Example here
Try changing your code to this
var bar = $('.div_layer_Class');
$('a.second_line').click(function(e) {
bar.addClass('on');
e.stopPropagation();
}).mouseover(function() {
bar.css('display','inline');
}).mouseout(function() {
if(!bar.hasClass('on'))
bar.css('display','none');
});
$(document).on('click',function(){
bar.removeClass('on');
bar.css('display','none');
//return false;
});
Two lines to look at, first, the e in function(e)
$('a.second_line').click(function(e) {
and the stop e.stopPropagation();
That basically stops any parent handlers being notified. Read here

I have written simple quiz with two cards. After user have clicked on the card, attribute clicked change status and answer is checked.
clicked = false;
$(document).on("click", "#card1", function() {
clicked = true;
check answer........
});
I have got antoher on click event, which should load next question when user click on body element.
This event should only work when the card is clicked and clicked status is true.
$(document).on("click", "body", function() {
if (clicked == true) {
quiz.nextQuestion();
clicked = false;
}
});
But these two onclick events start and execute simultaneously.
How can I prevent this?
stopPropagation(); can be used for this. Otherwise click on elements inside will also trigger the body click functions.
One more thing is that, we have to give click for <html> rather than <body>.
Description: Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
clicked = false;
$(document).on("click", "#card1", function(e) {
e.stopPropagation();
clicked = true;
console.log('click card');
});
$(document).on("click", "html", function(e) {
if (clicked == true) {
console.log('click body');
clicked = false;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div id="card1">
Card1
</div>
</body>
Simple...
clicked = false;
$(document).on("click", "#card1", function() {
clicked = true;
//check answer........
$(this).on("click", "body", function() {
if (clicked == true) {
quiz.nextQuestion();
clicked = false;
}
});
});
Hope this helps.....
You can do it by changing the status of clicked as true after you have checked the answer.
$(document).on("click", "#card1", function() {
check answer........
clicked = true;
});
This will make sure that clicked is not made true as soon as the click event is fired hence making the if statement in the second part of the code false
OR
You can even do it by
clicked = 0;
$(document).on("click", "#card1", function() {
clicked = 1;
check answer........
});
$(document).on("click", "body", function() {
if (clicked == 2) {
quiz.nextQuestion();
clicked = 0;
}else
{
clicked +=1;
}
});
I am trying to add a click function that triggers when a button is clicked. I am also trying to figure out how to add a double click function onto the same element, that triggers a different event.
var click = false;
onEvent("image2", "click", function(event) {
click = true;
});
if (click === true) {
setTimeout(function() {
onEvent("image2", "click", function(event) {
setScreen("safeScreen");
console.log("double click");
});
}, 200);
} else {
onEvent("image2", "dblclick", function(event) {
setScreen("safeScreen");
console.log("click");
});
}
This code is completely wrong, but I don't know where to start/correct. What am I doing wrong?
You should replace click with dblclick

I have a draggable <div> with a click event and without any event for drag,
but after I drag <div> the click event is apply to <div>.
How can prevent of click event after drag?
$(function(){
$('div').bind('click', function(){
$(this).toggleClass('orange');
});
$('div').draggable();
});
http://jsfiddle.net/prince4prodigy/aG72R/
FIRST attach the draggable event, THEN the click event:
$(function(){
$('div').draggable();
$('div').click(function(){
$(this).toggleClass('orange');
});
});
Try it here:
http://jsfiddle.net/aG72R/55/
With an ES6 class (No jQuery)
To achieve this in javascript without the help of jQuery you can add and remove an event handler.
First create functions that will be added and removed form event listeners
flagged () {
this.isScrolled = true;
}
and this to stop all events on an event
preventClick (event) {
event.preventDefault();
event.stopImmediatePropagation();
}
Then add the flag when the mousedown and mousemove events are triggered one after the other.
element.addEventListener('mousedown', () => {
element.addEventListener('mousemove', flagged);
});
Remember to remove this on a mouse up so we don't get a huge stack of events repeated on this element.
element.addEventListener('mouseup', () => {
element.removeEventListener('mousemove', flagged);
});
Finally inside the mouseup event on our element we can use the flag logic to add and remove the click.
element.addEventListener('mouseup', (e) => {
if (this.isScrolled) {
e.target.addEventListener('click', preventClick);
} else {
e.target.removeEventListener('click', preventClick);
}
this.isScrolled = false;
element.removeEventListener('mousemove', flagged);
});
In the above example above I am targeting the real target that is clicked, so if this were a slider I would be targeting the image and not the main gallery element. to target the main element just change the add/remove event listeners like this.
element.addEventListener('mouseup', (e) => {
if (this.isScrolled) {
element.addEventListener('click', preventClick);
} else {
element.removeEventListener('click', preventClick);
}
this.isScrolled = false;
element.removeEventListener('mousemove', flagged);
});
Conclusion
By setting anonymous functions to const we don't have to bind them. Also this way they kind of have a "handle" allowing s to remove the specific function from the event instead of the entire set of functions on the event.
I made a solution with data and setTimeout. Maybe better than helper classes.
<div id="dragbox"></div>
and
$(function(){
$('#dragbox').bind('click', function(){
if($(this).data('dragging')) return;
$(this).toggleClass('orange');
});
$('#dragbox').draggable({
start: function(event, ui){
$(this).data('dragging', true);
},
stop: function(event, ui){
setTimeout(function(){
$(event.target).data('dragging', false);
}, 1);
}
});
});
Check the fiddle.
This should work:
$(function(){
$('div').draggable({
start: function(event, ui) {
$(this).addClass('noclick');
}
});
$('div').click(function(event) {
if ($(this).hasClass('noclick')) {
$(this).removeClass('noclick');
}
else {
$(this).toggleClass('orange');
}
});
});
DEMO
You can do it without jQuery UI draggable. Just using common 'click' and 'dragstart' events:
$('div').on('dragstart', function (e) {
e.preventDefault();
$(this).data('dragging', true);
}).on('click', function (e) {
if ($(this).data('dragging')) {
e.preventDefault();
$(this).data('dragging', false);
}
});
You can just check for jQuery UI's ui-draggable-dragging class on the draggable. If it's there, don't continue the click event, else, do. jQuery UI handles the setting and removal of this class, so you don't have to. :)
Code:
$(function(){
$('div').bind('click', function(){
if( $(this).hasClass('ui-draggable-dragging') ) { return false; }
$(this).toggleClass('orange');
});
$('div').draggable();
});
With React
This code is for React users, checked the draggedRef when mouse up.
I didn`t use click event. The click event checked by the mouse up event.
const draggedRef = useRef(false);
...
<button
type="button"
onMouseDown={() => (draggedRef.current = false)}
onMouseMove={() => (draggedRef.current = true)}
onMouseUp={() => {
if (draggedRef.current) return;
setLayerOpened(!layerOpened);
}}
>
BTN
</button>
I had the same problem (tho with p5.js) and I solved it by having a global lastDraggedAt variable, which was updated when the drag event ran. In the click event, I just checked if the last drag was less than 0.1 seconds ago.
function mouseDragged() {
// other code
lastDraggedAt = Date.now();
}
function mouseClicked() {
if (Date.now() - lastDraggedAt < 100)
return; // its just firing due to a drag so ignore
// other code
}
How can I stop this function from happening twice when a user clicks too fast?
$(document).ready(function() {
$(".jTscroller a").click(function(event) {
event.preventDefault();
var target = $(this).attr("href");
$("#photo").fadeTo("fast", 0, function() {
$("#photo").attr("src",target);
$("#photo").load(function() {
$("#photo").fadeTo("fast", 1);
});
});
});
});
The issue I'm having is that if a user clicks too fast the element won't fade back in, it just stays hidden.
The issue wasn't what I thought it was. When I was clicking on the same thumbnail it would try to load in the same image and stick loading forever. The .stop() answer does fix double animation so I'm accepting that answer, but my solution was to check if the last clicked item was the currently displayed item. New script:
$(document).ready(function() {
$(".jTscroller a").click(function(event) {
event.preventDefault();
var last = $("#photo").attr("src");
var target = $(this).attr("href");
if (last != target) {
$("#photo").stop().fadeTo("fast", 0, function() {
$("#photo").attr("src",target);
$("#photo").load(function() {
$("#photo").fadeTo("fast", 1);
});
});
};
});
});
Well you use the correct word in your descripton. Use stop()
$("#photo").stop().fadeTo("fast", 0, function() {
You may use a setTimeout function to make a delay between click grabs. I mean, a second click will be processed only after sometime, after the first click. It sets an interval between clicks.
$(document).ready(function() {
var loaded = true;
$(".jTscroller a").click(function(event) {
if(!loaded) return;
loaded = false;
event.preventDefault();
var target = $(this).attr("href");
$("#photo").fadeTo("fast", 0, function() {
$("#photo").attr("src",target);
$("#photo").load(function() {
$("#photo").fadeTo("fast", 1);
loaded = true;
});
});
});
});
Keep track of its state
I believe what you are looking for is .stop()
http://api.jquery.com/stop/
$("#photo").stop(false, false).fadeTo()
I would prevent it like this:
var photo = $("#photo");
if (0 == photo.queue("fx").length) {
foto.fadeTo();
}
I differs from stop as it will only fire when all animations on this element are done. Also storing the element in a variable will save you some time, because the selector has to grab the element only once.
Use on() and off() :
$(document).ready(function() {
$(".jTscroller a").on('click', changeImage);
function changeImage(e) {
e.preventDefault();
$(e.target).off('click');
$("#photo").fadeOut("fast", function() {
this.src = e.target.href;
this.onload = function() {
$(this).fadeIn("fast");
$(e.target).on('click', changeImage);
});
});
}
});

When I click on customer support a div is shown
What I want is when someone clicks out of the div, the div should hide, I tried a couple of things, but they don't seem to work..
$(document.body).one("click", function() {$(".cust-support-outer").hide();
});
Also:
$("body").click(function(e){
if(e.target.className !== "csupport-drop")
{
$(".cust-support-outer").hide();
}
});
Would appreciate any help...

I did this change in your js and worked
try this, use this js code
$(function(){
$(".csupport-drop").click(function(){
$(".csupport-drop").addClass("active-drop-tab");
$(".cust-support-outer").show();
return false
});
$(document).bind("click", function(e) {
if(!$(e.target).hasClass("get-daily-alerts-outer")){
$(".get-daily-alerts-outer").hide()
}
});
$(".close").click(function(){$(".get-daily-alerts-outer").hide();
return false
});
$(".get-deal-alerts").click(function(){$(".get-daily-alerts-outer").show();
return false
});
});
I just changed how you bind the "click" event to the document and pass the Event object to the function so you can check over what element the click event was fire.
Try:
var mouse_is_inside = false;
$(document).ready(function()
{
$('.cust-support-outer').hover(function(){
mouse_is_inside=true;
}, function(){
mouse_is_inside=false;
});
$("body").mouseup(function(){
if(! mouse_is_inside) $('.cust-support-outer').hide();
});
});
Bind this to body
$("body").click(function() {
if ($(this).attr("class") == "cust-support-outer") {
// inside
} else {
// not inside
}
});
