I have a parent element with mouse up and mouse down events attached on it, and a child element with a click event attached.
Is there any way to prevent the click event from happening in the child, after the mouseup event has been triggered in the parent?
An example, on the JSfiddle here, the goal is to make the inner square not turn to green if I click on it.
Ideally I would like to do it without modifying the $('#inner').on('click', function(){}). I already know that I can set a boolean on mouseup and check it on click but i'm trying to find a way to do it without modifying the click event.
Using jquery(or any other library) is option and I don't really have any restrictions other than not modifying the click method.
EDIT
Thanks #adeneo for the suggestion, that looks promising but it made me realize I missed a big part of the problem. Inside mouseup there will be a conditional check to see if the click should be prevented or not. If I remove the event can I somehow add it back after the click has been avoided? In a setTimeout for example. I'm not sure how(or if it's possible) to get the reference to the removed click function and then re-add the handler.
Hopefully this new fiddle here helps me to explain it a little bit better!
$('#inner').on('mouseup', function(e) {
$(this).unbind("click");
$(this).css({'background': 'black'});
});
Did you try like this?
Try e.stopImmediatePropagation(); in your inner code.
Just replace your code with the below code and check. To stop the click event of the inner div you can use preventDefault() or stopPropagation(). Please check below
$('#inner').on('click', function(e) {
$(this).stopPropagation();
// or
// $(this).preventDefault();
alert('inner click');
});
$('#outer').on('mousedown', function(e) {
$(this).css({'background': 'green'});
});
$('#outer').on('mouseup', function(e) {
$(this).css({'background': 'yellow'});
});
I'm pretty sure that this is the answer you're looking for :
$($(this)).children().click(function (event) { // Preveu la propagació del click als fills
// event.stopPropagation();
});

I'm trying to prevent the defined onclick events of the children of an element being run by returning false from the mousedown event on the container like so:
submit_container.mousedown(function(event){
return false;
});
If I write my code like this, it doesn't work. However, if I add an alert first, the click events are in fact stopped:
submit_container.mousedown(function(event){
alert('Alert');
return false;
});
The same issue was alluded to here, but sadly none of the answers address this.
EDIT: JSfiddle example. I want the behaviour of the second link, but without having to trigger an alert
The mousedown is working for the container class . Your problem is that a href has a click event attached to it not mouse down. So you should be using onclick on the container or the href as event Propagation will occur and bubble up to the parent . You can still stop this from happening .
Example.
submit_container.click(function(event){
event.stopPropagation();
event.preventDefault();
return false;
});
Hope this helps
Are you using jQuery? Try with a "preventDefault" method:
submit_container.mousedown(function(event){
event.preventDefault();
return false;
});
I have kind of strange problem.
I'm trying to add a couple of events to som DOM elements (all existing, some initially hidden:
$self.on("focus", function () {
$self.next().css("display", "inline-block");
});
$self.on("blur", function () {
$(this).next().hide();
});
$self.parent().find(".icon-ok").on("click", function() {
console.log("icon.ok")
});
You can see the relevant part of the DOM here (self is the span user-name):
Later on, the element eventually because visible and I can click on it. However, the event handler is never called. If I remove the blur event, than the click event works. However, I need both.
What's going on here?
How can I fix it?
Looks like the blur cancels out the click (due to event order) but using mousedown instead of blur may help you get both.
UPDATE: Added code based on comment
$self.parent().find(".icon-ok").on("mousedown", function() {
console.log("icon.ok")
});
Your problem might be the classic delegation problem, where in the element is not available in the DOM when the event is bound.
Delegate the event and see if that solves your problem.
$self.on("click", ".icon-ok", function() {
console.log("icon.ok")
});
User $self if that element is visible or any closest ancestor that you can find which is always present in the DOM.
I dynamically add this
$(ele).on("mouseover")
when user has mouse over the element, but it seems that mouseover event triggers only when I reenter element.
Here is example in jsFiddle (Click on <div> to add event listener)
How can I achieve this without manually triggering .mouseover() ?
Best solution I came up with was (Thanks to Brandon's suggestion):
Store x,y pos in document (drops performance on webpage a bit):
$(document).mousemove(function (e) {
// Set global values
window.mouseXPos = e.pageX;
window.mouseYPos = e.pageY;
});
And then when animation is finished:
$(document.elementFromPoint(window.mouseXPos, window.mouseYPos)).trigger("mouseenter");
You can't. mouseover only triggers when the mouse crosses the boundary of the element. Once the mouse is within the element, it won't trigger. Your question suggests you might need to take a step back and re-examine your problem. If you are taking action when the mouse is already within the element then why do you need a mouseover event?
You can manually trigger a mouseover with the trigger jQuery function after attaching you eventhandler this way
$(".test").on("click",function(){
$(this).on("mouseover",function(){
alert("");
});
$(this).trigger('mouseover');
})
I have a 'li' that pops down when I click on a 'link' via jquery's 'click'.
Does anyone know of a clean way to do something along the lines of 'offclick'? As in, when I click off of the element, it would hide the pop down?
Thanks!

You would want to assign a click listener to the window and also assign the click listener to your link. Inside the link click listener, you'll want to stop the event propagation so it doesn't travel up the DOM tree and fire your window's click listener.
Something like this should do the trick:
$(window).click(function(){
$('li#my_li').slideUp();
});
$('a#my_link').click(function(event){
try
{
event.stopPropagation();
}
catch(err)
{
// IE does it this way
window.event.cancelBubble=true;
}
$('li#my_li').slideDown();
});
I guess you could look at blur, which is called when the element looses focus:
ref: http://api.jquery.com/blur/
You can use blur or focusout depending on your needs
I was trying to setup this "when you click outside of the element, close it" type of thing using some code I found on Stackoverflow:
$(document).click(function() {
$('.list-to-hide').hide();
});
$('.show-list-button').click(function(event) {
event.stopPropagation();
});
Could someone explain the later part with stopPropagation? I don't understand why it's needed.
Thanks!

Imagine this:
<div>
DIV
<span>
Span
</span>
<div>
and:
$('div').click(function() { alert('div clicked'); });
$('span').click(function() { alert('span clicked'); });
Check out what happens when you click each one
When you click the span, it happens to also trigger the div because your also clicking the div.
Now if we wanted to alert the span only we need to stop the div click from triggering when we click on the span so we do this:
$('div').click(function() { alert('div clicked'); });
$('span').click(function(e) { alert('span clicked'); e.stopPropagation(); });
See what happens now
Your example code is missing a vital part:
$(document).click(function() {
$('.list-to-hide').hide();
});
$('.show-list-button').click(function(event) {
event.stopPropagation();
$('.list-to-hide').show();
});
Without the event.stopPropagation(), it would show the list, and then hide it because the .show-list-button is inside the $(document) so both click handlers would fire. event.stopPropagation() basically says only apply this click event to THIS CHILD NODE and don't tell the parent containers anything because I don't want them to react.
Think about it this way - you rent a taxi for $100. The driver gives his company $80. event.stopPropagation() is like telling him to keep all $100 because the company doesn't need to know anything about the ride.
event.stopPropagation(); prevents the event from bubbling up the DOM. Without this line, clicking on .show-list-button the click handler for document will fire also. With it, the document click will not fire.
Have you read this ?
http://api.jquery.com/event.stopPropagation/
It prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
Example
Kill the bubbling on the click event.
$("p").click(function(event){
event.stopPropagation();
// do something
});
