Windows 8 JavaScript运行时错误：NotFoundError-Metro

我使用WinJS.Navigation.navigate加载新页面。我使用这个代码行，它从Metro库抛出一个奇怪的异常。当我把它评论出来时，它运行得很好。为什么?

代码：

例外情况：

'WWAHost.exe' (Script): Loaded 'Script Code (MSAppHost/1.0)'. 
Exception was thrown at line 5200, column 4 in ms-appx://tiponspackage/js/jquery.js
0x800a139e - JavaScript runtime error: SyntaxError
Exception was thrown but not handled in user code at line 84, column 29 in ms-appx://tiponspackage/js/navigator.js
0x800a139e - JavaScript runtime error: NotFoundError
The program '[5864] WWAHost.exe' has exited with code -1 (0xffffffff).

您是否在about.html中加载了任何JS？是的，about.html包括about.JS需要查看代码-错误似乎来自jquery，因此我怀疑about.JS中的某些内容导致了错误。您是否在about.html中加载了任何JS？是的，about.html includes about.js需要查看代码-错误似乎来自jquery，因此我怀疑about.js中的某些内容导致了错误
