How to show alerts/popups/windows using knockout.js

Question

I think we shouldn't have references to html elements in viewmodel. So I think I can't do $('#id').dialog() or shouldn't do alert('message') or window.open(). Then how should I do it?

Answer 1

Take a look at this answer for a sample of using a custom binding to control a jQuery UI dialog from your view model.

Setting an observable to true opens the dialog, setting it to false closes it.
