Documentation:Finding angular scope from javascript

Working with EXT_Components and integrating towards other services you may end up in situations where you get callbacks in client side javascript - and you will want to catch data from such a callback.

To get hold of your objects from such a callback (that are outside of the normal angular realm where you have some scope information at hand) you can go like this:

var vmroot=angular.element('#viewmodelWrapper').controller().$scope.ViewModelRoot;

You now have the current local representation of your ViewModel in the vmroot variable and you can set properties like this:

vmroot.MyViewModelColumn=somevalueFromACallBack;

MDrivenTurnkey sees the property you change and handles signaling of server and binding of UI.

With some defensive error checking:

      function GetVMRoot(){
	var ctrl=angular.element('#viewmodelWrapper').controller();
        if (ctrl !== undefined){
           return ctrl.$scope.ViewModelRoot;
        }					
        return undefined;      
      }
