Add reverse() function to jQuery core

Why isn't there a reverse() function in the jQuery core, to reverse the order of objects in a jQuery collection? This is a very simple thing to implement, yet I feel it should be in the core so that people can quickly get the functionality instead of having to hunt it down on the web and define their own function. Something like this should do:

jQuery.fn.reverse = Array.prototype.reverse;

Forgot to mention; typical use case for this function:


alert('contents of child: ' + jQuery(this).text());

I think this might indeed be useful, lets see what the others have to say

I second rwaldron's comments. This looks like it should belong in core and has been requested outside the tracker a number of times over the past few years.

I see that Brandon touched upon this too last year

+1 on this. It's barely any code to implement, and I've had to provide it to a lot of people who have asked over time.

The ticket seems to have 0 votes at the moment ... :)

Most jQuery operations return nodes in document order, so we'd need to document what happens if other operations are performed after a reverse.

After some discussion dmethvin, ajpiano and me came to the conclusion that adding a reverse function to the core wouldn't be of great use. Especially if you consider chaining and that most other methods would immediately restore the dom-order of the elements.

If you just need the current elements in the set in reverse order just do

//get a plain array of elements then call reverse on that

If you insist having this as a method on the jQuery object you can monkey patch it using something along these lines

$.fn.reverse = Array.prototype.reverse
