如何在jQuery中移动HTML元素？

Question

My HTML structure is like this:

<div id="parent">
   <div id="1">Some content</div>
   <div id="2">Some content</div>
</div>

I want to move the element id="2" to place before id="1" so its will be like this:

<div id="parent">
   <div id="2">Some content</div>
   <div id="1">Some content</div>
</div>

How do I do something like that in jQuery?

Answer 1

You can use .insertBefore() , like this:

$("#2").insertBefore("#1");

Or, .prependTo() , like this:

$("#2").prependTo("#parent");

...or the reverse using #1 and .insertAfter() and .appendTo() ...or several other ways actually, it just depends what you're actually after, the above 2 methods should be about the shortest possible though, given 2 IDs.

I'm assuming this is just an example, remember to use IDs that don't start with a number in an actual HTML4 page, they're invalid and cause several issues.

Answer 2

简单地说：

$('#1').before($('#2'));

Answer 3

有没有想过使用jQuery UI Sortable ？
