Graceful handling of anchors with jQuery

Over at they have an interesting post on handling anchors gracefully with jQuery.

Below is an excerpt from the post:

I've come to use this quite often which eventually leads to a considerable amount of if statements.

Which is ugly. And since I don't like ugliness, I've coded myself a small anchor handler for jQuery. Looking at the code I think I could quite easily make it compatible with the Prototype framework too, but I'll keep that for another post :D

  url = window.location.href, handlers = [];

    anchorHandler: {
      add: function(regexp, callback) {

        if (typeof(regexp) == 'object') {
, function(arg){

            args = {r: arg[0], cb: arg[1]};});}

        else  args = {r: regexp, cb: callback};

        return jQuery.anchorHandler;

  })(document).ready(function(){, function(handler){

      match = url.match(handler.r) && url.match(handler.r)[0] || false;

      if (match) {
      	handler.cb.apply(this, [match, (url.match(/#.*/)[0] || false)]);


And I can add triggers like this:

  .add(/\/\#ch\-cheatsheet/,    h.comment.showCheatsheet)

  .add(/\/\#comment\-compose/,  h.comment.showCompose)
  .add(/\/\#comment\-\d+/,      h.comment.focus);

The first argument is a regular expression or a string that is passed to the function match, the second argument is the callback function.

The method also accept arrays as argument like this:

  [/\/\#ch\-cheatsheet/,   h.comment.showCheatsheet],

  [/\/\#comment\-compose/, h.comment.showCompose],
  [/\/\#comment\-\d+/,     h.comment.focus]]);

The callback function receive 2 arguments. The matched bit of the anchor with the anchor itself.

This technique is very useful for downgrading your applications on browsers where JavaScript is disabled.
