Changing the Action attribute of Form

I need to pass control of a form to either a page that accesses our database, and displays the data, OR to a page that contains static content. The ACTION attribute will then depend on the contents of 1 of the input fields in the form, which is a SELECT type of input. Here is an example of what the form looks like: <form id="test" action="some_page.php" method="get" name="test"> <select name="test_item" size="1"> <option value="1">Item 1</option> <option value="2">Item 2</option> </select> <input type="submit" name="submit" value="submit" /> </form> If "Item 1" is selected, I want to go to a certain page (some_page.php), and if "Item 2" is selected I want to go to a different page. Is there a way to handle this using PHP or JavaScript? Any help would be greatly appreciated! Thanks!
