I have a 6 digit number field that I would like to verify is in fact a number. Basically it is passing right over it.
No validation and no stopping of the script.....What am I missing? I do have several other tests that work fine in similar format...just not this one.....

Any assistance would be great....Thanks

here is the code:

CODE


<form method="post" name="f1" action="PartSave.asp" onsubmit="return checkscript()" ><b><font size="6" face="Tahoma">


<script type="text/javascript">

//validation routine

function checkscript() {
//check that partNum is actually a number
if (isNaN(f1.partNum.value)){
alert('Please Re-enter 6 numeric digits only!');
return false;
}

return true;
}

</script>

Part No: <input type=text name=partNum><br>

I think you need to change
CODE
if (isNaN(f1.partNum.value)){
to
CODE
if (isNaN(document.f1.partNum.value)){


I didn't try it out, but I'm pretty sure that should fix it.

Thanks, but I had tried that with no change... I also tried just using partNum.value ....unfortunately same result.

Ah you are correct, that does not change anything. I suppose I'm confused as to how you are calling the function.
CODE
<form method="post" name="f1" action="PartSave.asp" onsubmit="return checkscript()" ><b><font size="6" face="Tahoma">
The function is sound (I tested it with a button onclick event) which leads me to believe that its the problem arises from the way you are calling the function. I'll try to look at it some more today if I get the time.
