<p>当传递参数时，这个方法是 <code>.bind('focusout', handler)</code> 的快捷方式，当不传递参数的时候，是<code>.trigger('focusout')</code> 的快捷方式。</p>
|
|
<p>This method is a shortcut for <code>.on('focusout', handler)</code> when passed arguments, and <code>.trigger('focusout')</code> when no arguments are passed.</p>
|
|
<p><code>focusout</code> 事件会在元素（或者其内部的任何元素）失去焦点时触发。这跟 <a href="/blur">blur</a> 事件的显著区别在于，它可以在父元素上检测子元素失去焦点的情况(换而言之，它支持事件冒泡)。</p>
|
|
<p>这个事件通常会跟 <a href="/focusin">focusin</a> 事件一起使用。</p>
