jquery reverse order of children

Reverse the order of children:

(function($){
 $.fn.reverse = function(){  
  return this.each(function(){
   var i,
    $this = $(this),
    children = $this.children(),
    last_index = children.length - 1,
    last_child = $(children[last_index]);
   
   for (i = 0; i < last_index; ++i)
   {
    last_child.after($(children[i]).detach());
   };
  });
 };
})(jQuery);

download jquery

Once or twice a month I'll find myself working on some random little project with a web UI and so of course I need jquery at which point I wonder if I have the latest version.. hence, a little script to get the latest and greatest:

#!/bin/bash

wget $(\
 wget -qO - http://docs.jquery.com/Downloading_jQuery |\
 sed -rn 's#^.*(http://code.jquery.com/jquery-[[:digit:]]+.[[:digit:]]+.[[:digit:]]+.min.js).*$#\1#p' |\
 head -n 1
 )

todo: check local jquery copy to see if there actually is a new version we need to download
