WinJS.Application.onerror exception and grab StackTrace

Question

In my WinJS, Windows 8.1 app I have a global exception handler in default.js like this

WinJS.Application.onerror = function(err) {
    //  handle the excep here
    var msg = err.detail.errorMessage;
    var the_path =  err.detail.errorUrl;
    var the_line = err.detail.errorLine;
}

How do I grab the stack trace here so I can report it? - or the call stack I guess.

Thanks

Hi Phil,

Since Windows Store App for HTML5/WinJS is using the same render engine as IE, so simply search this question on the Internet. If the solution works fine with IE, then it should work as same as Windows Store App.

You could use some third party library for helping with collect the stack trace, for instance a post from StackOverFlow suggest to use stacktrace.js for helping with this.
