Child element click event trigger the parent click event

问题

Say you have some code like this:

<html>
<head>
</head>
<body>
   <div id=\"parentDiv\" onclick=\"alert(\'parentDiv\');\">
       <div id=\"childDiv\" onclick=\"alert(\'childDiv\');\">
       </div>   
    </div>
</body>
</html>

I don\'t want to trigger the parentDiv click event when I click on the childDiv, How can I do this?

Updated

Also, what is the execution sequence of these two event?

回答1:

You need to use event.stopPropagation()

Live Demo

$('#childDiv').click(function(event){
    event.stopPropagation();
    alert(event.target.id);
});

event.stopPropagation()

Description: Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.

Without jQuery : DEMO

 <div id="parentDiv" onclick="alert('parentDiv');">
   <div id="childDiv" onclick="alert('childDiv');event.cancelBubble=true;">
     AAA
   </div>   
</div>

I faced the same problem and solve it by this method. html :

<div id="parentDiv">
   <div id="childDiv">
     AAA
   </div>
    BBBB
</div>

JS:

$(document).ready(function(){
 $("#parentDiv").click(function(e){
   if(e.target.id=="childDiv"){
     childEvent();
   } else {
     parentEvent();
   }
 });
});

function childEvent(){
    alert("child event");
}

function parentEvent(){
    alert("paren event");
}

回答4:

The stopPropagation() method stops the bubbling of an event to parent elements, preventing any parent handlers from being notified of the event.

You can use the method event.isPropagationStopped() to know whether this method was ever called (on that event object).

Syntax:

Here is the simple syntax to use this method:

event.stopPropagation()

Example:

$("div").click(function(event) {
    alert("This is : " + $(this).prop('id'));

    // Comment the following to see the difference
    event.stopPropagation();
});

回答5:

Click event Bubbles, now what is meant by bubbling, a good point to starts is here. you can use event.stopPropagation(), if you don't want that event should propagate further.

Also a good link to refer on MDN
