Disabling a button on a form

[AnnIsabelle]

Hi,
I'm making a form with a button on it. The button has an onClick-event that calls a function. After the first time the user has clicked the button,I want to disable it. This way the user can only click once. I need this because the function I call checks the answer given by the user and, if correct, increases a score. Now the user can click an indefinite number of times and augment the score.

Thanks,
AnnIsabelle

I have seen it done using a toggle variable. After it is clicked once it changed the onclick event to onblur whick keeps them from clicking it again.

You can get the actual code from JavaScript pros over at that forum.
