Subject [jira] [Commented] (CB-6991) Weinre doesn't fails to load in browsers without a development console
Date Fri, 20 Jun 2014 14:49:24 GMT


Joshua Walsh commented on CB-6991:

In my testing this issue occurred on all mobile platforms.

Make a simple webpage. No external scripts, no dependencies or includes. In the body, make
a div with an id of 'test' and immediately below that make a script block:

document.getElementById('test').innerText = typeof(window.console);

Execute this on a desktop browser. You should see 'object' on the page. Execute on a mobile
device and you should see 'undefined' instead.

I was able to reproduce this issue on all of operating systems above. I used the Firefox app
on Android, and it's irrelevant which browser I used on iOS and WP as they are all forced
to use the same engine anyway.

As for buying a cheap device, you can use Windows Phone 8.0 SDK to make a WP8 emulator for
free. Install the SDK, launch Visual Studio, make a new Windows Phone 8.0 App project and
click on the launch emulator option. The browser is properly emulated to use the exact same
engine as present on a real Windows Phone.

Additionally, this issue applies to version 2.0.0-pre-HH0SN197 of Weinre, but I don't know
which version of Cordova that maps to.
> This issue has been a massive pain to debug, as the issue is not present on desktop computers
and there are no debugging tools on mobile devices, hence why I need Weinre in the first place!
In fact, the issue is even more specific than that: The issue affects all browsers WITHOUT
debugging tools.
> The error is: "Unable to set property __original of undefined or null reference." The
issue occurs on line 172 of Console.amd.js. In order to fix it, I added the following lines
of code above line 168:
> if(!window.console)
> {
> 	window.console = {};
> }
> I'm sure there's a more elegant way of solving this, but it does the trick.
> Good luck!
