Hi Jeffrey,
to access a JavaScript variable from the Iframe use the DOM window from
the Iframe. To get the window use this:
var domWindow = this.iframe.getWindow();
Now you can access your variable like this:
domWindow.variableName
But please attend that in some Browsers like IE the "load" event
arrived, but the JavaScript is not completely initialized. I couldn't
fix the issue with Fabian, so check the existence from the variable
first. If the variable doesn't exist, try the access with a timer later.
Have a look in the inspector (Application.js method: "__checkWorking")
there is done the access with a timer.
Cheers,
Chris
