javascript - jQuery .on() and .delegate() doesn't work on iPad

Question

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

If you try this snippet on desktop, everything works.
Whenever you try it on iPad, it won't do anything.

$('body').on('click', '#click', function() {
    alert("This alert won't work on iPad");
});

div { 
  font-size: 24px; 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="click">Click here</div>

It's a Safari mobile bug/feature : click events won't bubble all the way up to body.

Adding onclick="" is a known workaround, but IMHO it's easier to attach your listener on a first child of <body>.
