How to rearrange elements using jQuery?

How to rearrange elements using jQuery ?

Orginal Code :

<p id="paragraph1">1</p>
<p id="paragraph2">2</p>
<p id="paragraph3">3</p>
<p id="paragraph4">4</p>
<p id="paragraph5">5</p>

After Rearrange (put p3 in p2's place)

<p id="paragraph1">1</p>
<p id="paragraph3">3</p>
<p id="paragraph2">2</p>
<p id="paragraph4"&开发者_JAVA百科gt;4</p>
<p id="paragraph5">5</p>

You can use .insertBefore():

$("#paragraph3").insertBefore("#paragraph2");

Slightly more elaborate example (clicking on a paragraph moves it up):

$("p").click(function() {
   $(this).insertBefore($(this).prev()); 
});

You can test both examples here.
