I would like to let the user choose in a combo-box the category (this is simple) and then the sub-category in another combo-box containing only the subcategories of the selected category. With ASP I am used to download all the subcategories via an SQL at the page load and save the values in arrays. Then depending of the selected category load via Jscript the subcategories values dinamically.
This is a good question. I just stole Paul's Dr. Dobb's Journal and it describes (and provides javascript code!) for EXACTLY what you want. Unfortunately, the article is only in print until Feb :^( but the code is online at: http://www.ddj.com/ftp/2000/2000_01/dselect.zip Now it's not exactly well-commented so the article helps A LOT to understand it. Although I can't seem to reach the web server now, there is apparently a full working version of the script and associated HTML at: http://www.digitalpaper.com/ddj/dynamic.html HTH, --Rob
