Safari:焦点事件对按钮元素不起作用 [英] Safari: focus event doesn't work on button element

问题描述

focus 事件在所有浏览器上都可以正常工作，但在 Safari 上点击它后.

它在 div[tabindex] 元素上工作正常，但不适用于 button 或 input:button 元素.

当我使用 $('.btn').focus().

为什么点击时焦点事件没有触发?

这是我的代码:

$(".btn").focus(function (e) {$(".result").append("<p>Event:"+e.type+", target:"+e.target+"</p>");})

.result{min-height:200px;border:1px solid #000;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script><button class="btn">button 1</button><input type="button" class="btn" value="button 2"/><div class="btn" tabindex="0">div元素</div><h1>结果:<div class="result">

解决方案

$(".btn").mouseup(function(e){e.preventDefault();});

The focus event works fine on all browsers but Safari when it has been clicked.

And it works fine on div[tabindex] element, but don't work on button or input:button element.

It also can get the focus event when I use $('.btn').focus().

Why does the focus event haven't triggered on click ?

Here is my code:

$(".btn").focus(function (e) {
	$(".result").append("<p>Event:"+e.type+", target:"+e.target+"</p>");
})

.result{min-height:200px;border:1px solid #000;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button class="btn">button 1</button>
<input type="button" class="btn" value="button 2"/>
<div class="btn" tabindex="0">div element</div>
<h1>
Result:
</h1>
<div class="result">

</div>
