JQuery：如何在仍触发父onclick事件的同时停止子onclick事件

Question

I wonder how can I stop child onclick event while still triggering the parent onclick event. For example the following structure:

<div id="parent">
   <div id="child1"></div>
   <div id="child2"></div>
   <div id="child3"></div>
</div>

if I click "child1" for example, the onclick event for "child1" will not be triggered, however, the onclick event for "parent" will still be triggered.

Thank you very much!

Answer 1

最简单的方法是取消绑定孩子的事件处理程序。

$('#child1').unbind('click');

Answer 2

You could just pass the click to the parent?

$('.child1').click(function(e){
    e.preventDefault();
    $(this).parent('#parent').trigger('click');
});

When you click .child1, it will prevent the default action, and then trigger the click for the parent of child1 with an id of #parent.

Actually - probably ignore the above - as per the comment below it may cause bubbling. All you really need to do is use e.stopPropagation(); .

I've created a jsfiddle showing how although the child1 has a click function bound to it, it's being ignored, and so the parent click is only getting picked up.

do you mean:

$('#parent').on('click', function(e) { 
   if( e.target !== this ) {
       return;
   }
});
