getElementById is indeed the "standards-compliant" method... but something which came in a bit late!!! Browser IE 5+ and Netscape 6+ support them... but the earlier version browsers does not support getElementById (since these browsers date before the standard was introduced.

Also the standard practice followed for manipulating forms in the HTML document using JavaScript is the form array/object rather than getElementById. (Doesn't mean that you cannot/should not use getElementById) getElementById is introduced keeping in mind the DHTML parts and as a standard way to access the DOM elements which were not exposed as arrays/object for JavaScript. For e.g.. accessing the table cells/rows or DIV/SPAN elements etc to bring in DHTML effects.

Remember that getElementById is the "standards-compliant" method, the others are not, IIRC. They of course work too, but when manipulating DOM objects, getElementById is supposed to be used, according to the current standards.

Is there such a thing as casting in JS? I'm not sure. I don't think there is as far as object references go anyway, but I could be wrong.

I geuss, some thing working or not working in JavaScript is a lot dependent
   on what version of what browser, are you using.

   Well, Any ways, from my previous experience with JavaScript, usually

document.getElementById gives you an object, and casting it to form doesnt
   work all the time..

   it is always better to use document.forms[i].action .


   Thanks and Regards,

Why do you believe this does not work? I just tried in IE and it worked
   fine, as I would expect since I do this sort of thing all the time.

   I would suggest throwing an alert before and after the code setting the
   action, display what the action of the form is.  I did this and it does
   indeed change.
