41756 - [RFE] special-case console errors for document.layers, document.all

Status: VERIFIED WONTFIX

(Core :: DOM: Core & HTML, enhancement, P3)

Description

[Jesse Ruderman]

Splitting from bug 41636.

Mozilla should special-case the error messages shown on the javascript console 
for document.all and document.layers to make it clear that mozilla 
intentionally doesn't support document.all and document.layers, and to help 
webpage authors figure out how to fix their pages for mozilla.


Current

rties


Better

http://www.variety.com/scripts/iHorzNav.js line 11: document.layers has no prope
rties.  See http://sites.netscape.net/ekrock/standards.html for help migrating 
from document.layers and document.all to document.getElementById.


Problems with this idea

a = document.all;
a.foo.value = ""; // what error message do you get here?  
                  // bug 9378 [fixed] related

<tough_decision>Nice idea. Alas, out of time for new RFEs. 
Plus, this would be too complicated to implement--you'd have to 
have intelligent script analysis code that would understand 
things like code forks, etc. The right place to implement code 
analysis is in server-side CGI-based services that scan a page 
& generate a report, like WebSiteGarage, rather than in the 
browser itself. WONTFIX.</tough_decision>
