Is there a JavaScript API for Office Web Apps (specifically - Word Web App) that I can use in order to get notifications from the Word doc?My scenario is this:I have an ASP.NET application, in which I want to display a word document using the Word Web App (on premises). I would like to embed the document in the web page using iFrame (haven't tried it yet, hope it'll work...).I would like to get notification when the user saved the document, so that when this happens, I can remove the iFrame and display something else.Is that possible?
