[W8.1] Need JavaScript to detect long press on links

I am working on a browser on WinRT 8.1 using a WebView, I have some queries,

1. I am not able to catch some of the long press events on links. I know that I am missing some javascript but I am a beginner in JavaScript and need help for the same.

2. I am not able to open Ads embedded in websites in the same browser when I click on them, they open in IE. How do I open them in my webview?

3. When I load some sites for e.g, CNN.com in my webview, it crashes.
