Another way would be:



Within your js code, rather than referencing it on HTML element itself ... but the solution provided by other poster also works.

cross-browser event handling

I can't haggle on which approach is better because I am newbie myself, But If you have some time, you should do a look up on Event Model of W3C and google on "Non Obtrusive javascripting"

Being a newbie, I'd highly recommend looking into a library such as jQuery that make cross-browser things like events and Ajax a breeze.

P.S. Please do not post in all uppercase. I have fixed it for you.

To whom is this addressed?

You'll not find me arguing again Unobtrusive JavaScript; in fact, I wrote a book on it (with respect to jQuery).

I posted that tag to demonstrate how it cranks me up sometimes when we do things like <body onload="my entire script comes here, so have fun debugging this"></body> or something like that ... All I wanted to show this guy was, there are ways of doing this in a cross browser way and not stick onEvent stuff with js function calls ... I didn't intend to throw it out at you, I apologize if that caused you any concerns. No disrespect

I <3 JQuery! its such a sweet framework (I was a stickler for Dojo for a while, until I got hooked to JQuery, I am still learning it however ... ). What book are we talking about? I wanna get reference under my belt for JQuery, havent found anything handy except for documentation yet.

No one said you did anything wrong; I merely pointed out that the posted code was not cross-browser as that's important for any readers to know.
