matlab access variables created by Javascript

I am using active control to embed a webpage with matlab(this webpage is locally saved).

% Open Actxcontrol.
handles.ie = actxcontrol('Shell.Explorer.2',[10 10 321 392 ]);

% Open default map.
path = '...';
file = '...';
Navigate(handles.ie,[path, file]);

but really no idea is there a way to access the varialbes in the javascript of the webpage?

Thanks in advance.
