JavaScript Help

[Senkusha]

Hi, does anybody know where I can find a good site for JavaScript?

Basically this is my problem:  I have a series of buttons that when clicked will either add or subtract the current balance from a 'total pool'.

Say I have 1000 credits available.  I click on the "decrease" button and now the available credits should read 999.

Thank you!

I have another problem also that I need help with.

I have found code using ASP and Javascript to populate selections for other <select OPTION>  elements, but I can't translate it for PHP.  Below is an example:

First <select> element will contain:
  North America
  South America
  Asia
  Austrialla (sp??)
  Europe


The second <select> element will have it's options depend on the first:

IF <select1> = North America THEN options will be:
  United States
  Canada
The third <select> will also be based on <select1>:
  English
  French
  Spanish


IF <select1> = Asia THEN option will be:
  China
  Japan
  Russia
The third <select> will also be based on <select1>:
  Japanese
  Chinese
  Russian


Now here is the trick:  All of the options are read from a databse, so I was thinking of reading all the possible values into an array of sorts and then using Javascript to populate the <select> elements.  The problem is that I have no clue how to begin.  Any suggestions?

Thanks!
