To debug javascript code we use alert() whereever needed and it irritates you while alerts values inside a loop and other places where more alerts are being shown and you have to press the ok button to pass / proceed on.
here is a simple way to get rid of the alerts dialogs and get the values outputed into another debug window.

Format fractional digits in a numbe

Generates select boxes, text boxes, check boxes and radio buttons. Via a handful of functions.

Generates a tree view within a dropdown select box.

Given a PHP array (even a deep nested array), returns a string representation of that array as JavaScript array. Useful when using PHP to output JavaScript.

A quick and simple function to dump a variable (array, object, string, int, etc) out into -formatted output for a web browser.

If the variable is an array or an object, you can have it returned into the another variable for later processing (i.e., through templates or e-mail). Due to lack of free time, if the variable is not an array or an object, it will ignore the $return value and print directly to output.

Future revisions will add the above mentioned functionality.

This function is useful in helping to deter spam bots by obfuscating things such as e-mail addresses and URLs that are displayed on a web page. While it's not 100% fool proof, it does offer some protection.

Example:
$email = html_entitize('foo@baz.org');
/*
Outputs foo@baz.com
*/

A simple AJAX class. The code for the class is provided as well as example HTML and PHP code for usage.

A small example demonstrating inheritance in Javascript, complete with calling base class constructors and methods. For the more detailed description, visit http://www.adampresley.com.

For this we can use prototype's getTransport method.
