thanks.

I don't think IE supports onlick on the select tag. You may want to look at setting the onclick for the options tags inside the select.

Hi Ryan,

Can I let onclick refer to a function defined in the controller?

In HTML it's:

   onclick='Ajax.Request(...)'

In Ruby that's :onclick => 'Ajax.Request(...)', natch.

To get the ... part, write remote_function or link_to_remote into a web page and view its source. That will show you how to pack the Request arguments.

Sorry I am new to rails and don't understand your comments. I have a select box and I want whenever its value changed, other text field value will change accordingly. Could you please give me an example for this?

thanks.
