Subj : Convert non-READONLY property to READONLY property. To : netscape.public.mozilla.jseng From : J.P. Date : Mon Jul 12 2004 03:59 pm In my application, the type and value of a property has to been determined at runtime, which means that I can't set READONLY in JS_DefinePropety(). But after the type and value has been set on that property, I want it to be READONLY. Is there any way I can achieve that? Thanks. .
