#Mini DOM Ready

This code was inspired by Dustin Diaz and the smallest DOM ready code ever and is intended to be copied and pasted into the HEAD of your document.

This should work in IE6+, FF 3.6+, and everything else. If you would like to support FF < 3.6, then you will also need to include the following shim for document.readyState taken from here:

(function(h,a,c,k){if(h[a]==null&&h[c]){h[a]="loading";h[c](k,c=function(){h[a]="complete";h.removeEventListener(k,c,!1)},!1)}})(document,"readyState","addEventListener","DOMContentLoaded");

Dustin's technique uses polling to determine the state of the document, while this implementation uses native DOM events when possible, falling back to polling. I fealt it was worth sacrificing a few bytes for the sake of leveraging native DOM events whenever possible. I am fairly pleased with the result (.25 Kb minified). By default we create a global domReady method which should work exactly like the jQuery syntax:

//      $(function() { … });
// jQuery(function() { … });
domReady(function() { … });

You can even define your own method name in case you don't like the name "domReady". For example, you could change domReady to blah, then you could write the following code:

blah(function() { 
	alert("I'm not very good at naming functions.");
});

###Why is this useful?

Because you should be loading jQuery (and other scripts) at the very bottom of the page, immediately before the closing </body> tag. However, when using a CMS you might need to render some inline code which should execute on DOM ready… but jQuery hasn't loaded yet! So instead of writing the following:

$(function() {
	$('.slider').Swipe();
});

… you would instead write:

domReady(function() {
	$('.slider').Swipe();
});

##Tidbit You could rename "domReady" to a dollar sign $ or jQuery, which would allow for a seamless way to use jQuery syntax before it's even loaded. You could just keep your inline code the exact same. However, I advise against this as it will make your code confusing - others may think you have actually loaded jQuery.
