String To Uppercase

[ollmorris]

How do you make a string into uppercase? I have tried PHP's STRTOUPPER but it doesn't work.

Thanks

var string = "This is some text";
document.write(string.toUpperCase());

For what it's worth, in JavaScript there's no need to create a single use variable;

<script type="text/javascript">
<!--
document.write('This is some text.'.toUpperCase());
// -->
</script>
