Re: Multiple Keys

It's possible to check the value of window.location.host in Javascript,
and document.write() the code that uses the corresponding key back into
your HTML.

There's a trick to it, because <script> and </script> are magic words in
Javascript. You can't use them inside a quoted string. So you have to
write '<'+'script>' and '<'+'script>' like this:

<script type="text/javascript">

var key1 = '<' + 'script src="http://maps.google.com/maps?'
+ 'file=api&v=1&key=xxxxxxxxxx" type="text/javascript">'
+ '<' +'/script>';

var key2 = '<' + 'script src="http://maps.google.com/maps?'
+ 'file=api&v=1&key=yyyyyyyyyy" type="text/javascript">'
+ '<' +'/script>';

if (window.location.host == 'www.mydomain01.com') {
document.write(key1);
}
else {
document.write(key2);
}
</script>
