1. (function($) {
2.       // duck-punching to make attr() return a map
3.       var _old = $.fn.attr;
4.       $.fn.attr = function() {
5.       var a, aLength, attributes, map;
6.       if (this[0] && arguments.length === 0) {
7.             map = {};
8.             attributes = this[0].attributes;
9.             aLength = attributes.length;
10.             for (a = 0; a < aLength; a++) {
11.                   map[attributes[a].name.toLowerCase()] = attributes[a].value;
12.             }
13.             return map;
14.       } else {
15.             return _old.apply(this, arguments);
16.       }
17. }
18. }(jQuery));

Note the "toLowerCase()". I threw this in because I was lazy, and it suits my purposes but might not suit yours.

Now you can use .attr() without any arguments to get all arguments, in a similar way to using .data() to get all data.
