Regular Expression – Function Expected

**TryingToLearn** · Oct 15, 2007, 19:03

Hello

I am having an issue getting this regular expression to work in IE 7. This code works perfect in FireFox & Netscape, but it does not work in IE7. The error IE 7 gives me is:

Function Expected

Below is the code. Does anyone know why I am getting this error?

Code:

<html>
<head>

<script language="JavaScript">

function test()
{
   //-- Regular Expression to validate the entered Zip Code
   regZip = new RegExp(/(^\d{5}$)/);
      
   if( regZip( document.getElementById("zipCode").value ) )
   {
      alert("Thank you for entering a valid Zip Code");
   }
   else
   {
      alert("Entered Zip Code is not valid.");
   }
}

</script>
</head>
<body>

<input type="Text" id="zipCode" />
&nbsp;
<input type="Button" value="validate" onClick="test();" />

</body>
</html>

regZip= /(^\d{5}(\-\d{4})?$)/;
if( regZip.test(document.getElementById("zipCode").value ) ) {
alert("Thank you for entering a valid Zip Code");
}
else alert("Entered Zip Code is not valid.");

Not a great idea to call the function 'test'....

Thank you for pointing out that I needed to call the function…

regZip.test( )

As for the name, this is just a proof of concept but I would agree with you, test() would not be a good name for production code.

Thank you again for the help.
