Ok, so I was getting frustrated with the inability to hide data in javascript, as well as a number of other concerns with existing class structures (the requirement to use this.constructor in lieu of self, for example).

As a result, I've thrown together a nice little class constructor that accepts a class definition, as well as a class extender that allows you to build a new class from an existing one, with full access to all that private stuff.

This is a version of my previous entrant, Promise, that will work with prototype, but does not require it. It's slightly more advanced, using .apply here and there.

It's basically a function to allow any other function to poll. Polling is generally regarded as bad practice in object oriented code, but can make very simple the matter of, for example, running a bit of code only after a single-run event (like onload) occurs (whether that be in the future or past), another unrelated bit of code needs to be hack-tracked, or any other generic condition.

Note that when the function runs, it doesn't necessarily run within the scope that's called it. Its context is set to itself, rather than its normal context, and it's asynchronous, so you'll not get a return value. If you use Prototype, you can bind the function and it'll behave as it should in terms of context, but I'm unaware of a way to cause an asynch function to block execution - and you'd really rather that not happen anyway, trust me.

Prototype's Form.Methods library has a nice piece of code called 'serialize', which, if passed with the optional 'hash' parameter set to true, will convert an HTML form into a Javascript Object.

I was dismayed, however, to find that there was no way to reverse it; just as simply load a form using a Javascrip object.

So, here's one. enjoy.

Ok, so here's the deal. I've started to dally with Flash a bit, and I'm feeling all naked without my nifty Prototype functionality.

Most important to me are the bind() and curry() functions (though, others will rear their heads as my AS code gets more complex), Object.extend, and $A. They are para-ported here.

Simple. It's parse_url, from PHP, implemented in Javascript. Seen a lot of similar ones around the web, but they were all bulky code and none of them took advantage of the RegEx parser in JS.

Applied as a member of the String prototype, so just call as myURL.parseURL(); Will return a named object with naming identical to that of PHP's function.

Additional: if first argument is present, will break the querystring up into name/value pairs, unescaped, and return that instead of the raw querystriing.

A simple function (with support) that can provide the backbone to any templating system.
