一组HTML元素的颠倒顺序
问题描述:
我有一组看起来像这样的div:
I have a set of divs that looks like this:
<div id="con">
<div> 1 </div>
<div> 2 </div>
<div> 3 </div>
<div> 4 </div>
<div> 5 </div>
</div>
但我希望它们翻转以使其看起来像这样:
But I want them to flip so that it looks like this:
<div> 5 </div>
<div> 4 </div>
<div> 3 </div>
<div> 2 </div>
<div> 1 </div>
这样,当新的< div>
添加到列表末尾。
So that when a new <div>
is added it goes to the end of the list.
我该怎么做(或者有更好的方法呢?)
How can I do this (or is there a better way of doing this)?
答
包装为一个不错的jQuery函数,可用于任何选择集:
Wrapped up as a nice jQuery function available on any set of selections:
$.fn.reverseChildren = function() {
return this.each(function(){
var $this = $(this);
$this.children().each(function(){ $this.prepend(this) });
});
};
$('#con').reverseChildren();

编辑:已修复为支持任意jQuery选择
fixed to support arbitrary jQuery selections
