This script performs reliable, cross-browser input autofocus that often can be used simply by dropping it in, with no modifications to the form or HTML body. It refuses to switch focus if it detects that the user has interacted with the form (avoiding a major source of annoyance with autofocus scripts) and correctly handles Firefox tabs opened "in the background", which most autofocus scripts fail on. Official home is on the Lost Souls MUD Grimoire.

A simple, flexible formula for generating diminishing returns out of input numbers. Full explanation and home, with sample calculators and versions of the code in other languages, on the Lost Souls MUD Grimoire.

A wrapper on top of createElement for getting around IE problems with manipulating the name attribute. Unlike most solutions for this, it tests for which method to use once when the page loads rather than every time an element is created. By Chaos of Lost Souls MUD (a text-based fantasy RPG).

This script will allow for conditional loading of javascript libraries. The example here only has one condition to check for IE or Firefox then loads the appropriate .js file.

This is part of an .aspx template for an educational portal product.

Usage for loading the script:

I found this to be a neat little trick for hiding(somewhat) source javacscript code from peering eyes...

This function will unload all linked javascript files so that when you view source - you see no javascript files! (Especially helpful when using FF and using web-developer tools - no linked js files are displayed) The files remain resident in memory - allowing for the functions to work.

Just call the function in the tag

This code is used in an Educational Portal product but can be tweaked to fit your need.

This code adds a small icon next to the title of a 'portlet' that resides on the page. By clicking the portlet title, the portlet usually maximizes within the constraint of the portal template - but the extra icon allows for the portlet to be opened in it's own window.

This simulates an MDI interface.

This snippet allows an aspx page (c#) to accept URL parameters to allow styles or script to be dynamically appended to the rendered page.

I wrote this simple snippet to allow one of our vendors to accept a style override so that their application would morph into something more closely resembling our own portal application. Please see screenshots for clarification.

There seems to be so many hide/show scripts out there, so here's the functions I wrote and use on a regular basis - there are 7 functions, hide, show and toggle by id or class - and the getElementByClass function that does not exist as a built in Javascript function...

This is in response to the flurry of visibility scripts that just don't have all the pieces needed to make them totally useful.

This snippet also you to limit the input in a form field to a specified number of characters. It displays a counter so users can see how many characters they have left, and once they reach the limit the field just trims the length to your limit.

The following is a snippet from what I used when I implemented a tagboard to my site. Further revisions could/should read the LIMIT from the maxlength attribute
