disabled in Javascript function

does anyone know how can I write this using Netscape 4.7 :

function Allowfields()
{

document.Form1.field1.disabled=false;
document.Form1.field2.disabled=true;
}

This works perfectly under IE5 and not in Netscape...

Thanks

Well, I dunno about the 'disabled' property, but here is the Netscape JS reference for text objects:

One ad-hoc way top disable a text field is to do the following:

<BLOCKQUOTE><font size="1" face="Verdana,Arial,Helvetica">code:</font><HR><pre><input type=text onFocus="this.blur()">[/code]

This seems to work fine in NS4.72 (win).

So, rather than blur the focus everytime as above, make it so that it calls a function to test whether that field should be enabled.
