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.

Format fractional digits in a numbe

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.

so you executed a query that took .5 second to execute and you want to bind that to a windows control. next you decide that you will need to have two controls bound to the same datasource. not a problem, except when you do this:
control1.datasource = datatable
control2.datasource = datatable

you notice that each control mirrors the other and you cannot pick two seperate and distinct values.

one way to solve this is to create two datatables and execute the query twice. unfortunately this now doubles your query time. bad idea.

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.
