通过点击内部禁用 HREF

Question

How can I disable the a href if an element with an onclick function is fired within the <a> element?

I tried event.preventDefault(); , but it doesn't seem to do anything.
How can I solve this?

 $(function() { $(".inside > .fa").click(function(event) { event.preventDefault(); alert("TEST"); }); });

 <link href="//maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <a href='/'> <div class='button'> <div class='inside'> <i class="fa fa-globe"></i> </div> </div> </a>

Answer 1

The click still bubbles upwards. Use event.stopPropagation(); instead. You are using event.preventDefault() on an element that has no default click behaviour, so it does nothing.

 $(function() { $(".inside > .fa").click(function(e) { e.stopPropagation(); console.log(e.target); }); });

 a { display: block; /* required otherwise you cannot have block level elements like div inside a */ }

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <a href='https://google.com' target="_top"> <div class='button'> <div class='inside'> <i class="fa fa-globe"></i> </div> </div> </a>

Answer 2

尝试return false而不是event.preventDefault()来停止事件冒泡

Answer 3

Register your event listener on the <a> tag. And the make the changes below. This takes advantage of Event Delegation (a good thing).

you'll need both of these:

event.preventDefault();

Add

event.stopPropagation();

And then finally, you'll need to test to make sure the element clicked was not the <a> ; So your code will look like this:
