关于方法jquery.contains(container, contained)

[jack_liu4Ye]

<div id="111">
ddd
<div id="222">
ddd
<div id="333">
ddd
</div>
</div>
</div>

<script>
   alert(jQuery.contains($("#333"),$("#222")));
//或者alert(jQuery.contains($("#222"),$("#333")));
</script>

此方法，不管怎么写返回的都是true，很奇怪，求真相！！

<div id="111">

<div id="222">
ddd
<div id="333">
ddd
</div>
</div>
</div>

<script>
alert(jQuery.contains($("#333").get(0),$("#222").get(0)));
alert(jQuery.contains($("#222").get(0),$("#333").get(0)));

jQuery.contains( container, contained )
containerThe DOM element that may contain the other element.

containedThe DOM node that may be contained by the other element.

Example:

jQuery.contains(document.documentElement, document.body); // true
jQuery.contains(document.body, document.documentElement); // false

一个DOM节点是否包含另一个DOM节点
你传递的是jquery对象，不是dom元素
 alert(jQuery.contains($("#333")[0],$("#222")[0]));
