In a script I'm writing with JQuery I'm trying to add a click handler to a div, but ignoring clicks on the children a tags inside it.
You can see a JSFiddle of how I'm currently trying (and failing) to make it happen here: http://jsfiddle.net/q15s25Lx/1/
$(document).ready(function() {
$(document).on('click', '.post:not(a)', function(e) {
alert($(this).text());
});
});
<div class="post">This is some text in a div. Click me please.</div>
In my real page, the a tags all have their own click handlers, so I need to be able to listen for those concurrently.
So, ideally I'd like to use something like the :not() selector to ignore clicks on this particular handler.
Is something like this possible?
You'll need to add another handler that acts on the anchor and stops the event from propagating:
$(document).on('click', '.post a', function (e) {
e.stopPropagation();
e.preventDefault();
});
Without this, when you click the a the event bubbles up to the parent .post, and the handler fires on that anyway.
You need to stop event propagation to child elements using .stopPropagation():
$(document).on('click', '.post a', function(e) {
e.stopPropagation();
});
Working Demo
Just return false; in the end of event handler.
$(document).on('click', '.post', function (e) {
alert($(this).text());//will show entire text
});
$(document).on('click', '.post a', function (e) {
alert($(this).text());//will show 'text'
return false;
});

return false will server as both e.preventDefault() &
e.stopPropagation()
Try to stop the event from bubbling up the DOM tree using stopPropogation()
$(document).ready(function() {
$(document).on('click', '.post a', function(e) {
e.stopPropagation();
alert($(this).text());
});
});
Fiddle Demo
All of the other posts did not explain why your code failed. Your selector is saying : Find an element that has the class post and is not an anchor. It is NOT saying if a child was clicked and was an achor do not process.
Now there are two ways to solve it. One is to prevent the click from bubbling up from the anchors. You would add another listener on the anchors.
$(document).on('click', '.post a', function (evt) {
evt.stopPropagation(); //event will not travel up to the parent
});
$(document).on('click', '.post', function (evt) {
console.log("Click click");
});
Or the other option is not to add a second event, but check what was clicked.
$(document).on('click', '.post', function (evt) {
var target = $(evt.target); //get what was clicked on
if (target.is("a")) { //check to see if it is an anchor
return; // I am an anchor so I am exiting early
}
console.log("Click click");
});
Or jsut let jquery handle it all for you. return false
$(document).on('click', '.post:not(a)', function() {
alert($(this).text());
return false;
});

I created the below html with JavaScript and I want to be able to listen to the click on both the channel_li and client_li.
Generated HTML
<li cid="4" class="channel_li" style="display: list-item;">Random<ul class="client_ul">
<li class="client_li" clid="14" style="">Hanekawa</li></ul>
</li>
The second code snippet is the JavaScript I'm using to generate the elements and assign a click event. The problem I have is that when I click the channel_li nothing happens, and when I click on the client_li it triggers the channel_li listener. Is there anyway of fixing this?
JS
// Some generation code here.
// $li here is the created channel_li element.
$($li).on("click", "li", function() {
console.log("channel click");
});
// More generation code.
// $foo here is the client_li element.
$($foo).on('li', 'click', function () {
console.log("client click.")
});
You will need stopPropagation(): http://api.jquery.com/event.stoppropagation/, because nested elements are in question.
$(document).on("click", "li.channel_li", function() {
alert("channel click");
});
$(document).on("click", "li.client_li", function(e) {
e.stopPropagation();
alert("client click");
});
fiddle: http://jsfiddle.net/W68sa/1/
Your selector is wrong, becoue $li is not a variable or valid selector:
// $li here is the created channel_li element.
$($li).on("click", "li", function() {
console.log("channel click");
});
for
// $li here is the created channel_li element.
$(document).on("click", "li", function() {
console.log("channel click");
});
How you need trigger diferens events use the clase for:
// $li here is the created channel_li element.
$(document).on("click", ".client_li", function() {
console.log("Client click");
});
// $li here is the created channel_li element.
$(document).on("click", ".channel_li", function() {
e.stopPropagation();
console.log("Channel click");
});

I want to add custom context menu with jQuery for the whole body of the page, except the textfields. How can I do that?
I have tried that code:
$('body:not(input)').bind('contextmenu', function(){
/*code*/
});
Check the srcElement before plugin executions. If it's not an input element, do trigger the contextmenu plugin:
$(document).on("contextmenu", function(e) {
if (!$(e.srcElement).is(":input")) { // if it's not an input element...
$(this).triggerTheContextMenuPlugin();
}
});
Use an event listener on the document and check if it was initiated by an input element.
$(document).on("contextmenu", function (e) {
if (e.target.tagName.toUpperCase() === "INPUT") {
console.log("context menu triggered");
}
});
Demo here
Inspired by Salman's solution.
You can stop the event propagation in all input elements, with the e.stopPropagation() function. In doing so, you keep the default behavior of the inputs elements:
$(function() {
$(document).on("contextmenu", function(e) {
alert("Context menu triggered, preventing default");
e.preventDefault();
});
$("input").on("contextmenu", function(e) {
e.stopPropagation();
});
});
JSFiddle Demo
I have a table with some div's inside it.
I want an event to happen when I click on a td element, but I also want an event to happen when I click on a div element.
As you can see in this fiddle http://jsfiddle.net/rkGkp/1/ my problem is, when I click on the div element, both the div and td event is triggered, but I only want the div's event to be triggered.
I use these event listeners
$(function() {
$("#div").on("click", function() {
alert("a div is clicked");
});
});
$(function() {
$(".td").on("click", function() {
alert("a td is clicked");
});
});
What can I do to avoid the element behind my div to trigger an event?
Have a look here: FIDDLE
I used stopPropagation()
CODE
$("#div").on("click", function(event) {
event.stopPropagation();
alert("a div is clicked");
});
This is the easiest way to achieve what you need. Simply check if the click target is on the div:
$(function() {
$("#div").on("click", function() {
alert("a div is clicked");
});
});
$(function() {
$(".td").on("click", function(e) {
if(!$(e.target).is("#div")){
alert("a td is clicked");
}
});
});
looking at this event (being bind on 2 divs overlapping each other, look at the jsfiddle)
.on('contextmenu', function() { ... });
Why do both divs being triggered?
How can I detect this and or stop the underlaying div from triggering?

Thanks for any information!
On nested element, you need to stop event bubbling:
$('#div2').on('contextmenu', function(e) {
e.stopPropagation();
$('#log').append('<p>div2 triggered contextmenu!</p>');
});
DEMO
DEMO
$('#div1,#div2').on('contextmenu', function (e) {
e.stopPropagation();
$('#log').append('<p>' + e.target.id + ' triggered contextmenu!</p>');
});
event.target
event.stopPropagation/
You need to prevent event from propogating, try this code:
$('#div1').on('contextmenu', function(e) {
if(!e.isDefaultPrevented()){
$('#log').append('<p>div1 triggered contextmenu!</p>');
e.preventDefault();
}
});
$('#div2').on('contextmenu', function(e) {
if(!e.isDefaultPrevented()){
$('#log').append('<p>div2 triggered contextmenu!</p>');
e.preventDefault();
}
});
I'm trying to setup an event where it fires after my element is opened. So I have a tooltip and I have a click event which shows the tooltip. Then when that happens I setup a document click event that gets fired so if the user clicks anywhere on the stage it removes all tooltips. But what's happening is it gets called before the tooltip even gets a chance to show. So it's firing the document event over and over again.
$('.container img').popover({placement:'top', trigger:'manual', animation:true})
.click(function(evt){
evt.preventDefault();
el = $(this);
if(el.hasClass('active')){
el.popover('hide');
}else{
clearDocumentEvent();
el.popover('show');
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(){
hideAllTooltips();
});
}
el.toggleClass('active');
})
var hideAllTooltips = function(){
$('.container img').popover('hide');
$('.container img').removeClass('active');
}
var clearDocumentEvent = function(){
$(document).off('click.tooltip touchstart.tooltip');
};
The problem stems from event bubbling. You can verify this by doing the following test:
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(){
//hideAllTooltips();
console.log($(this)); // will return .container, body, html
});
Try using event.stopPropogation():
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(e){
e.stopPropagation();
hideAllTooltips();
});

Side note:
I recommend removing .tooltip from the on function like
$(document).on('click touchstart', ':not(.container img)', function(){
e.stopPropagation();
hideAllTooltips();
});
