Fatal error using Companion.JS with IE6 and "localhost" server / DebugBar forums

Emil G. · 2009-09-25 08:54:12

Hi all

I've just installed v0.5 within my old IE6. It works perfect ...

BUT

for developping purposes, I use a local Apache server in my computer. When I load a page from my "localhost" web, It produces a fatal error on IE (IE6 stops and produces a dump file) when console.log is called, whereas same page is working fine (Companion.JS works fine) when loaded from an "external" server ... If I desactivate Companion.JS, no more problem on localhost.

Anyone has an idea to fix this strange problem ?

Configuration :
Windows XP
IE v.6.0.2900
MS Debugger v. 1.0.7295
Companion.JS v0.5

In advanced options/ browser, both "script debug" options are activared.

Strange.

Can you provide a basic HTML page that is crashing IE?

Does it happens only when using console.log ? What arguments do you have on your console.log call ? Can you try with a simple text on console.log ?

Thanks.

I've tried console.log on a simple text ... and it works.

So my trouble comes from a difference between my "local environment" and "server environment".

After a deeper investigation, I found it ... and resolved it. I forgot to desactivate "console.log" declaration as a custom function (used before installing Companion.JS). Once desactivated, everything is normal.

I can therefore say that Companion.JS works perfectly on local environment.

Anyway, in my opinion the fatal error should not be normal. Only a JS error should have happened if trying to declare a function that already exists. I can give you my JS source code if you wish to investigate this point.

Thanks Fabrice.

Yes, I am interested by this bug. If you can provide an url or sample code so I can reproduce the problem that would be nice.

Thanks.

just add this line to your JS code :

console.log=function(){};

and IE will probably crash
