View Full Version : JS to disable form submit button?

I would like to make sure users do not click the submit button on my form more than once.

Is there some way to do this using Javascript?

:)thankx for your input!

<form onsubmit="document.getElementById('mysub').disabled=true;">

<input type="submit" id="mysub">

More than once, per page visit or more than once a day/week/month/year?
The code above will take care of preventing someone from submitting the form twice per page visit, but it would take a simple page refresh to get around it.

It's a useful trick though - it's amazing how many people double-click buttons and hyperlinks, and this can prevent forms from being submitted twice by mistake - with stuff like credit card purchases that can be quite serious.

once per page visit is fine for a limit.

i tried implementing the code above but my form just wouldnt submit at all...

am still working on it.

It will prevent repeated form submition using the "submit" button, but will not help when user presses "enter". I would use cookies for the task - maybe a bit extra work up front, but sure allows for much more flexibility if needed...

Try this
<form onsubmit="this.elements['mysub'].disabled=true;return true;">

<input type="submit" name="mysub">

</form>Vladdy -- what? onsubmit is fired by any submission except one triggered by the form's submit() method.
