DebugBar forums / console.log feature not working when refreshing page

fabrice · 2007-11-12 14:42:14

Hi,

Companion.JS v0.2 introduced the firebug "console.log" feature.
This feature is not working well when the page is refreshed.

I am working on it to correct the problem on the future release.

Great work on CompanionJS. Developing for IE is way easier with your tools.

I have 0.2 installed but console.log isn't working at all, not just when the page is refreshed. My console.log("blabla") line is highlighted in yellow under Source in CompanionJS, so it seems IE is treating it as a JavaScript error. All the JavaScript in the same function after that line is skipped.

Merci encore.

Georges

Hi Georges,

Some other users reported this problem. I couldn't have a chance to reproduce it on my development environment.

If you are interested in debugging and correct this problem with me feel free to answer here or contact me at contact@debugbar.com .

Thanks.

I'm having the same issue.

It started recently, and I can't think of any reason why - I haven't updated anything or installed anything new, haven't changed any settings in IE. I don't use IE as my browser, I use it only for testing and debugging IE-specific quirks.

From the console, I discovered something fishy:

Code:

In [10]=
    console.toString()
Out[10]=
    "function console(msg)   var obj = getElement('console');  if (obj)     var text = getInner(obj);    text = msg + '<br>' + text;    setInner(obj, text);  "

Not sure what goes wrong, but it looks like "console" in the global scope has somehow been overwritten by a function, it's not an object at all??

Are you using a javascript framework like jquery, dojo, prototype ? Or firebug lite ? Or installed another IE plugin that already handles console.log feature ?

mindplay.dk · 2008-10-02 19:40:55

I am using jQuery on ExtJS - no plugins. Should that be a problem?

mindplay.dk · 2008-10-02 19:51:42

I searched through all loaded JavaScript files, the word "console" does not figure anywhere. Ext has something called createConsole(), but it's not touching anything that variable.

To confirm that, I also tried putting a window.alert(console.toString()) as the first line in the <head> on my page - it's already been overwritten at this point, so whatever is causing this, it's something within the browser itself.

I do have the Microsoft IE Developer Toolbar installed, but it doesn't have a console, so I don't know how that would affect it?

mindplay.dk · 2008-10-02 19:55:10

Also tried disabling all other plugins, including Java and the Microsoft IE Developer Toolbar - the situation is the same.

fabrice · 2008-10-02 20:16:26

And when you disable Companion.JS, (there are 2 plugins with the names : "Companion.JS" and "Companion.JS BHO") ? Do you still have a "console" object defined ?
If so, there is something on your config or your page.
Are you using IE8 or UE 7 ? which OS ?

Do you have a public url where I can see the loaded page ?

Argh! Turns out the developer who was working on this before me thought it was clever to create a function in the global scope named console() ... I searched everywhere for this, until finally I just did a "find in files" from the root directory, and sure enough, somewhere in there, somebody overwrote the console object.

I suggest anyone else experiencing this problem try the same - find in files...

I also would like to suggest that, in Companion.JS, after a page load (and DOM complete), do a check for the console object, and issue a warning in the popup or console. You could probably even list the filename and linenumber where the overwriting function/object was defined? Might save others some headaches :-)

... and you from having to answer this question again ;-)

Good idea, I will do it in a future version.
