HowToJavaScriptGlobalVars

Using global vars in JavaScript

You can use Variables that area usable in every subfunction of a JavaScript area by using the "var" operator.

example:
<script language="JavaScript">
	var PopupText="Hello World!";
	function PopMeUp()
	{
		alert ( PopupText );
	}
	PopMeUp();
</script>

If you would load a site containing this script - the script would pop up a message to you, that shows "hello world!"
