function blocking waiting for user interaction

[ext237]

hello.

I'm trying to halt a function's execution while waiting for user
interaction.

For example, I have a function called getUserValue() that pops up a hidden
div containing several buttons. Each button sets a value. I want use a
function to pop the box, wait for the users' button press, and then continue
the function based on what the user presses.

Behold, simi-code:

function getUserValue() {
... lots of code ...
var returnValue = doPopBox();
... lots more code based on users selection in doPopBox();
}

I've written quite a bit of supporting code, but the getUserValue()
continues to execute after the box is popped up, even before the user
presses a button.

I used setTimeout() to check to see if the button has been pressed -- but
when the timer starts, the interface is locked and a button cannot be
pressed. I also tried using a recursive function, (check value=null, if it
is, recheck), but Firefox and IE apparently don't like what may seem like an
unending recursive loop.

Is anyone doing this already in code? Any suggestions?

Thanks!

Sorry, not possible.
Instead, display what you need to, then when user interaction happens, act
on it.

Instead, just try to prevent the user from doing anything until they act on
the popup. Do this either using the browser's built-in modal dialog (if
supported) or a simulated modal dialog like:

Yikes. Wanted to do a global find/replace on confirm boxes for our app.
Thanks for the reply.
