Javascript based Validation
This will be very easy for someone I'm sure...
How would I tell the form not to submit if a certain fields is equal to 1? I need to do this with Javascript which I'm sure is very simple.
<?php
<head>
<script language=\"javascript\">
function isValidResolution() {
if document.theForm.Resolution == 1;
{
alert('You must select a valid resolution');
return false;
}
}
</script>
</head>
?>Am I on the right track with that idea?

<script language="javascript">function isValidResolution()

if (document.theForm.Resolution == "1");
{
alert('You must select a valid resolution');
}
}
</script>
I think...
Shakespeare: onclick || !(onclick)

Hi artsapimp,
As Jack implies, you need to surround your condition with parentheses. Also, if Resolution is a text field, you are better off putting the value you are comparing in quotes.
In addition, your form tag must be either using the onSubmit property:
In either case, you need to return false as you had originally.

I know I did something wrong, but I can't find it.
Here's the top of my code...
<?php<!-- #Include File = \"cnn.inc\" -->
<%
'Define SQL statements
strResultSQL = \"SELECT * FROM Result ORDER by Result\"
strDowngradedSQL = \"SELECT * FROM Downgraded ORDER by Downgraded\"
strPerceptionSQL = \"SELECT * FROM Perception\"
strChurnedSQL = \"SELECT * FROM Churned ORDER by Churned\"
?>
<script language=\"javascript\">
function isValidResolution()
{
If (document.theForm.Result.value == \"8\");
{
alert('You must select a result');
return false;
}
}
</script>
Outbound Tracking
Number:
Mailbox Setup?
Yes
No
Result of Call:
<?phprst.Open strResultSQL, cnn
Do Until rst.EOF
?>
<?php= rst(\"Result\")
?>
<?phprst.MoveNext
Loop
rst.Close
?>
?>
Thanks for any help.

I'm getting an error "object expected" and then it submits the forms. I tried a few things but it's still not working. What is wrong with this?
<?php
<script language=\"javascript\">
function isValidResolution()
{
If (document.theForm.Result.value == \"8\");
{
alert('You must select a result');
return false;
}
}
</script>
<link rel=\"stylesheet\" type=\"text/css\" href=\"/webday/style.css\">
<script language=\"javascript\" src=\"../../validate.js\">
</script>
</head>
<body bgcolor=\"#000000\">
<center>
<form action=\"Submit1.asp\" method=\"Post\" name=\"theForm\" onSubmit=\"return isValidResolution()\">
?>
Thanks again for any help.

Hi artsapimp,
1)
If (document.theForm.Result.value == "8");
should be:
if .....
(javascript is case-sensitive)
"Result" is a selection list? If so,
if (document.theForm.Result.options[document.theForm.Result.selectedIndex].value == '8');

It is a select box but I still got an error. I changed it to just lower case i and it worked as the first example.
Thanks for your help.

Hi artsapimp,
You're welcome, though I'm not sure what you mean and glad it's up and running

I kept it in this format...
if (document.theForm.Result.value == "8");
with the lowercase i and in "if" and it worked.
I thought you were saying in a drop-down box I would need to change the format to the 2nd example above but that didn't work for me.
