Guide's Function Library
A collection of functions that you can use as a basis for building your own scripts so that you don't have to start from scratch.
Dynamic Forms
This Form object makes dynamically generating forms using JavaScript fairly simple. Each form field is created by calling the appropriate method and passing a few parameters. Labels are also created and linked to the associated form field.

Posting Values using JavaScript
While a regular link has to pass any variables to the next page via the querystring, the addition of some simple JavaScript will allow us to post the values instead.

Cross Browser DOM Script
There are three different Document Object Models used by the various different web browsers. This code will determine which of the three that a given browser supports and provides a function that you can call to allow your code to work with all three DOMs.

Object Functions
A collection of javascript functions that return information about objects on the web page. If you need to know where an object is, how big it is or whether it is visible then these functions will tell you.

Maths Array
The mathArray class allows you to perform lots of numerical calculations on all of the entries in an array. It should make writing code that involves several numeric arrays and lots of interaction between them much easier.

Split Text Line
This function will assist you when you want to break up a piece of text into multiple lines so that it fits within a specified line length. The function inserts extra line breaks between words so as to give the maximum length line that is not longer than your specified maximum and without splitting any words (unless the words are more than one line long).

Browser Detection
Many people using browsers other than Internet Explorer set their browser to report itself as IE because of all of the scripts that people use that don't recognise the other browsers as existing let alone being able to run everything IE can and more. This script works out what browser your visitor is really using regardless of what they have set it to report as.
