Proper case a string

convert An integer to a string

This code allows you to set the "opcity" style attribute on a element without affecting it's content.

Just call the function for a specific element or to all elements of a given classname after the document loads.

Examples and advanced usage here...

This code snippet will validate an IP Address (IP v4).
return true if the ip address is valid. Else false.

convert a string to intege

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.

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.

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.
