document.write form validation of Enter Key

[xencade]

I need a script that is solely written as a .js file. It needs to use document.write statements. Could someone could provide me with a simple example that does the following:

Any form name, as a button type.
If the cursor is a active in the input field, the enter key needs to be checked and execute a function within the same .js file.

I can get the button to work, but hitting enter makes the page just refresh...

can you show the relevant code?

This js file is simply being referenced by a html file as a script src tag. The form at the bottom of this js file will load. The enter zip section is the section I need an enter key validated in addition to pressing the GO button.

var weatherstate;
weatherstate='show';


function GO()
{
//Check if zipcode entered is a number
if (isNaN(document.zipsearch.findzip.value))
{
alert('Please Use Numerical Values Only');
document.zipsearch.findzip.focus();
return;
}
{
var zipcodepars = document.zipsearch.findzip.value;
// document.write(zipcodepars)
//location.href="
