Form Confirmation - Cancel Doesn't Cancel.

[DaVuLf]

I have a form on my page.

[code]
<form action="insert.php" method="post">
[/code]

I have a submit button on the page.
[code]
<input name="Submit" onclick="confirmation()" type="Submit" />
[/code]

I have a confirmation function.
[code]
<script type="text/javascript">
<!--
function confirmation() {
    var answer = confirm("Is this transaction information correct?")
        if (answer){
            return true;
        }else{
            return false;
        }
}
//-->
</script>
[/code]

Now I'm wondering why when I click submit, and it asks for confirmation, and I click cancel, it still submits the form. Shouldn't it just let me fill in more data? Or correct what was incorrect. The whole point of confirmation seems to suggest that if the data is incorrect, that we have the opportunity to modify it before submission. Unfortunately, it seems to me like that isn't happening in this instance.

Any help would be appreciated.

Thanks,
DaVuLf

i think you need to do this:

[code]
  <input name="Submit" onclick="return confirmation();" type="Submit" />
[/code]

That did the trick.

What is the difference?

[wildteen88]

the added keyword [b]return[/b] before you call the confirmation function with in the onclick attribute on you input tag, Without that your form won't submit.

I noticed what he had added, which changed the way it worked, but I was wondeirng why. In reality, the form itself was still submitting, and the actions were being processed. The issue was that the cancel portion was not working.

Regardless, it is working now, and for that I must thank Lead.

Because the onclick event must return the value 'false' in order to cancel the submission. Without explicitly returning the value from your confirmation function, it just gets lost and the default value is returned from the event, which is "true".

Thanks Arthur, that's exactly what I was looking for.
