'Windows' is undefined in iframe

Question

I have an iframe that runs in web-context and inside it there is a list view. When i use touch to invoke a list view item, an exception is thrown: 

Unhandled exception at line 15768, column 13 in ms-appx-web://microsoft.winjs.1.0/js/ui.js
0x800a1391 - JavaScript runtime error: 'Windows' is undefined

line 15768, column 13 in ms-appx-web://microsoft.winjs.1.0/js/ui.js:

Do anyone have any experience on how to solve this?

Answer 1

Web-context is just that. Your iFrame is just a little web browser that's hosted in your app. 

You don't want any random website to be able to access Windows APIs (and thereby access a user's PC and personal data). Anything you want done in an iframe needs to be written the same way you would write a regular web-app.

Answer 2

Aha, that explains it, thanks.
