Knockout NavAway Binding Handler

An unobtrusive KnockoutJS Binding Handler for prompting a user with an "You have unsaved work" prompt upon navigating away from a page that may have unsaved viewmodel changes.

TODO

This project is a work in progress at the moment. Here are a few pending tasks:

• Host the example page.
• Write up the usage documentation.
• Expose a ko.navaway object:
  • Allow consumers to update what the initial state is (i.e. ajax save and now you need what's on the page to be the initial state). ko.navaway.updateToCurrent()
  • Allow consumers to query if there are any changes on the page. ko.navaway.pageDirty()
  • Allow consumers to programmatically reset the page to its original state. ko.navaway.reset()
• More test cases.
• More jasmine tests.
