Lets say I have divB inside divA. I have a click event on divA.
But how to check if divB inside divA is also clicked?
jsFiddle - http://jsfiddle.net/zwxK6/
The Script -
$('#divA').on('click', function() {
//What to do here? how to check if divB inside divA is clicked also?
});
Try this:
$('#divA').on('click', function() {
alert('divA is clicked');
});
$('#divB').on('click', function(e) {
e.stopPropagation();
alert('divB is clicked');
});
DEMO HERE
Use event object to get the source of event, pass event object to function you are binding for click, event.target will give you source of event.
Live Demo
$('#divA').on('click', function(event) {
alert(event.target.id);
//Use event.target.id to check if divB inside divA is clicked also
});
This will click the divA and then divB get clicked too.
You can find like this: http://jsfiddle.net/zwxK6/4/
function fireIt(id) {
alert(id + " is clicked too.");
}
$(function() {
$('#divA').on('click', function(e) {
$(e.target.id).children('div').click(
fireIt($(e.target).children('div').attr('id'))
);
});
});

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;
});
working fiddle: http://jsfiddle.net/q15s25Lx/2/
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 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?
DEMO: jsfiddle
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();
});
DEMO:
http://jsfiddle.net/dirtyd77/uPHk6/8/
Side note:
I recommend removing .tooltip from the on function like
$(document).on('click touchstart', ':not(.container img)', function(){
e.stopPropagation();
hideAllTooltips();
});
i have problem with click event. click to another element with event(click), doesn't count like click elsewhere. I want active one element or none.
demo: http://jsfiddle.net/WP4RH/
code:
$('span').click(function(){
var $this = $(this);
if($this.hasClass('active')){
$this.removeClass('active')}
else $this.addClass('active');
$('div').click(function(){
if (!$this.has(this).length) {
$this.removeClass('active');
}
});
return false;
});
Add this at the beginning of your span event handler:
$('.active').removeClass('active');
Demo
This is assuming that you want multiple clicks on the same span to retain active. If you don't want that, then let me know and I can modify the code.
For starters, You should move the div handler outside and then removeClass based on div element.
$('span').click(function(e) {
e.stopPropagation();
$(this).parent().find('span').removeClass('active');
$(this).toggleClass('active');
});
$('div').click(function() {
$(this).find('span').removeClass('active');
});
DEMO: http://jsfiddle.net/WP4RH/1/
Don't bind a click handler inside a click handler, just check if the target is the div or the span inside the click handler instead. Also, when adding the active class to this, just remove it on any sibling span :
$('span').on('click', function(){
$(this).toggleClass('active').siblings('span').removeClass('active');
});
$('div').on('click', function(e){
if (e.target == this) $('span').removeClass('active');
});
FIDDLE
If you want to keep the toggle-off functionality when the span itself has been clicked, then you can use the following. Also, note that you're binding an event handler each time a span is clicked.
http://jsfiddle.net/WP4RH/7/
$("span").click(function() {
$(this).siblings("span").removeClass("active"); // remove from other spans
$(this).toggleClass("active"); // toggle this span
return false;
});
$("div").click(function() {
$(this).find("span").removeClass("active"); // remove from all spans
});
