When developing Windows 8 apps with C# / XAML you can embed a third-party web page into an application using the WebView control.
What’s the equivalent for WinJS? IFrame? HtmlControl?
My requirement is that I’m building a content reader application and I need to be able to render third-party web pages in-app without blowing up the WinJS security sand-box or without scraping out the relevant content from each third-party web page.
You can use the IFrame to open a third-party web page within your application using the html control
<iframe>.You also have to set the URIs you want to include/exclude in your application in your package.appxmanifest in the Content URIs tab.
