form.action

[Rainman]

In my <form> tag, I leave off the action='...' specification because I
supply this later inside an onclick event handler, depending on which
button was pushed.

Inside the handler, I have...

form.action = 'index.php?cl=1234';

I added:

alert(form.action);

and verified that 'index.php?cl=1234' appears in the window, but the
page that appeared showed a URL of 'index.php?' without the 'cl=1234'
part. Why can't I give query-string parameters in the form.action
property? How can I pass either GET or POST variables to my target page
when those variable are created in the Javascript function?

Hi Mark

If you know what GET/POST vars may be used in advance you can add some
<input type="hidden" name=""> fields to the html and set their values
later.

If you dont know in advance you could add input elements as needed
using dom methods.

Afraid I don't know why it doesn't work as it is

Bad idea. The `action' attribute is required. And what about users
without client-side script support?

Use two (or more) submit buttons with different names and/or values,
then evaluate the submit button name/value on the receiving side.
No client-side script is needed on the sending side.
