问题
I'm trying to debug a bug that's only showing on IOS 6 Safari, from what I know. Chrome and Opera don't exhibit this bug.
I have reproduced the bug on my iPad 2 and the iOS Simulator, but only in the production environment. However, when I go into the safari Web Inspector (either iPad or simulator), the bug no longer occurs.
Any idea how to figure out what type of error I'm dealing with? I believe it's a JS error, but don't know where.
-- UPDATE --
To give a better idea of the workflow:
I load the page the exhibits the error. I plug in the iPad to my Mac, open a Safari window, then open a Develop > iPad > myTab. Then I hit reload on the page, and it doesn't exhibit the error.
-- UPDATEx2 --
I was able to get an error by opening it up in Opera Mini, then opening a tab and going to "server:console", which showed the error. Not exactly helpful when dealing with Safari-exclusive bugs, give it seemed to work.
And btw, the bug was an undefined JS variable.
