BLANK FIELD VALIDATION

This JavaScript ensures that the user enters a value into your form fields before allowing them to submit the form:

 

<HTML><HEAD>
<TITLE>ASP Web Pro</TITLE>

<SCRIPT LANGUAGE="JavaScript"'>
function validate() {
if (document.Subscribe.Name.value.length < 1) {
alert("Please enter a Customer Name.");
return false;
}
if (document.Subscribe.Email.value.length < 1) {
alert("Please enter an Email Address.");
return false;
}
return true;
}
</SCRIPT>

</HEAD>

<BODY>

<FORM name="Subscribe" Action="resultspage.asp" onSubmit="return validate();">
<input type="text" name="Name">
<input type="text" name="Email">
<input type=submit value="Submit">
</FORM>

</BODY>
</HTML>
