Hi John,
This is probably understood, but just in case, if you choose Chuck's
method #3 below, you might need some way to differentiate between the
user checking the checkbox and the user pressing the submit button,
since both will submit the form. One way that comes to mind to do
this would be a hidden field that is cleared in your body's onLoad
method and set in the checkbox's onClick before the submit.
Hmmm, thinking more about this, does form.submit() send the submit
button's value (like "enter" being pressed in a text field)? If not,
you might could tie one action to the form and another to the
button. Something to try.... ;-)
Regards,
Mark

John,
There are three ways you can do this:
1. JavaScript that you write that modifies the page on the fly
2. JavaScript that someone else wrote - the Ajax framework in
Project Wonder. That framework is an amazing piece of work and
really makes using Ajax with WO very simple - if you understand
WO. If you are just learning, it might be more head pain than you
want.
3. Use a tiny bit of JavaScript to get the form to submit and re-
draw with the pop disabled. This is fairly easy, but means a round
trip to the server that the user can see.
For #3:
1. Mark the form as multipleSubmit=true;
2. Add a specific action method for your Submit button and bind it
to the action of that button
3. Add this binding to the checkbox:
onClick="this.form.submit():"
I am assuming that you already have the code and template to handle
the box being in checked and unchecked states.

Hi, I'm a new member, first post. I know this is an easy
question, but I
can't find the answer elsewhere.
I have a form with a submit button, a checkbox, and a popup list.
I want the
popup list to become disabled if the checkbox is checked.
Everything works
fine, but when the user checks the checkbox, I can't get get the
form to
redraw with the popuplist disabled. I can set the popuplist to
disabled, but
it is not refreshed, so it can still be selected. Thanks for any
help,
John
