A question about the form

[Ning Du]

Hi,
In one of my JSP page I have two SELECT fields in a form,the requirment is that the options of the second SELECT field changes along with the selected option of the first SELECT field. How can I do that? JavaScript?

[sunitha reghu]

yes you can do that using a javascript. If the no of records are few then using JS is not a problem. But if the number of records are big say abt 800
then using using wddx u can do that.

Adu,
Sunitha is saying that if you have a select box with huge number of entries then using JavaScript is not a good solution. In most cases it should be OK.
You can populate javascript arrays and do all the processing on client side or use server side processing thus reloading the page when an option is selected in the first select box.

IHTH
