I have a function that runs onunload.
Is there a way that when someone clicks a different button on the page, and it runs a different function, is there a way to cancel and make sure the onunload won't run?

use a input with type = button
and not a submit button

set the onclick attribute of this button to run the different function

Try adding
window.onunload=null;

Open in new window

somewhere in your function to cancel the onunload call.

leakim971,

I think rivkamak is looking for a way to cancel the onunload call.  There seems to already be a function called when a button is clicked.

In your example (onclik should be onclick, I think), in  a_different_function() adding the line I posted above would cancel the onunload function.

My onlick submits the page. But I don't want the onunload to happen when you click the submit button.
If the form submits but I put value="no unload", then the unload wont' happen?

Try something like this
<script type="text/javascript">
function cancelUnload() {
    window.onunload = null;
    return true;
}
</script>

...

<input type="submit" value="Submit" onClick="return cancelUnload();" />

Open in new window


The value property of your submit button will not affect anything.

If you already have a function that gets called with the onclick, then add the line
window.onunload=null;

Open in new window

to that function, as I suggested above.

If this doesn't help you, then post the code you're using.
