Change form action

I have a search-form with this code:

What I wan't is to change the form-action to the chosen value of the option-menu, but I don't know how to do this. Any idea?

It probably makes more sense to have your select box contain values that you test against server side, performing the appropriate search depending on which option was selected. There's probably a way to change the form action, but relying on javascript to do this clumsily seems to me like a bad option. You have more control server-side.

are you using PHP, ASP, CGI? either way you should be able to set that as a variable that ties to a drop menu . that might work, i think.

To alter the form using JS, use the event handler called onChange in your select box
Your jumpTo() function will contain code which grabs the selected select box option (if u need a hand doing this let me know... it can be tricky).

The bit that actually changes the forms action is simply:
(this will be a line in your jumpTo() function.)

Thank's for responding everybody. I'm using ASP.

Right now I'm using a Dreamweaver MX Javascript, it kind of work's, but it's not perfect (I think).

If someone have a example I will be glad.

Here's one way of doing it. The example here is not very re-usable, though it gives you a general idea of how it works. Also, they use a button to trigger the link, rather than using the onChange handler (which I prefer - but means a user must have JS enabled).
