I am adding a data validation to my code. I want to make sure the event title is not blank, and the zip code entered is valid. The javascript does not work. Can you tell me why?
<form name="form1" action="organize.php" onSubmit="return validateform1();" method="post" enctype="multipart/form-data">
<div class="form-element">
<label for="event_title">Event Title</label>
<input type="text" name="event_title" id="dob" />
</div>
<div class="form-element">
<label for="zip">Zip Code</label>
<input type="text" name="zip" id="dob" />
</div>
<script language="javascript">
function validateform1(){
var zipcode = /^\+?([0-9]{2})\)?[-. ]?([0-9]{4})[-. ]?([0-9]{4})$/;
if(document.form1.event_title.value==""){
alert("Enter a title");
return false;
}
else if((!document.form1.zip.value.match(zipcode)){
alert("wrong zip format");
return false;
}
</script>
</form>
