jQuery sort elements by position in page

Question

I want to sort elements by position in the page. Meaning if I have an object:

$obj = $('#div1, #div2, #div3');

But my markup is like:

<div id="div3"></div>
<div id="div1"></div>
<div id="div2"></div>

How would I sort $obj to be $('#div3, #div1, #div2');

Thanks!

ok if they start with a same prefix you can do something like this

$obj = $('[id^=div]');
