How to sort divs according to their id using jQuery?

I'd use the tinysort plugin:

In your case it would be something like:

$("#container > div").tsort("",{attr:"id"});

There are plugins and the like to do sorting of elements. If you plan on actually re-ordering the DOM elements, you should probably use one of them.

If you just want a sorted list of the divs, you can use Javascript - since arrays can be sorted using a custom comparison function. You can convert the selected set of <div>s into an array using toArray() and then sort them using this mechanism.

$('#container > div').toArray().sort( function(a,b) { a.id - b.id } );

You could also use the detach() and appendTo() method to remove and the re-insert the elements in sorted order. However, this may not be the most efficient way to re-order the DOM elements.
