Javascript: Variable scope question

Mon May 17 11:37:44 PDT 2004

Are you explicitly accessing the dom i.e using window. or document. ?

Also are you using methods defined in a later javascript version while the 
browser only paritially supports EMCAScript or javascript 1.whatever 

netscape has some great js resources

http://developer.netscape.com/docs/manuals/js/core/jsref14/index.htm

<body>
<form name="form1" action="none">
   Big long form
   <input type=checkbox name=checkbox1>
</form>
<script language="javascript">
document.form1.checkbox1.checked = true;
</script>
</body>
</html>
