Disabling a button

[mraghu]

I am looking for a common javascript code that will disable a button in all the BROWSER versions? Browsers supported are IE, NS and AOL. Thanks.

document.getElementById("cmd_click").disabled=true

I don't think getElementById is going to work in lower versions of NS like 4.08, 4.77 etc., I wish to avoid writing verison specific code. Any other ideas?

From the original thread (http://forums.webdeveloper.com/showthread.php?s=&threadid=11138), posted by gil davis:
In fact, the image button does not appear in the form's elements array. So, even my example will not work in NS 4.x. You'll have to change the <input type="image"> to a simple image link with an onclick that submits the form for you, if you want it to work in NS 4.x.

If I don't use <input type="image"> and instead I use <input type="button">, then, how do I disable the button in all broswer versions(IE, NS,AOL) using a common Javascript code?
