i'm developing facebook app but i want when user reach at the end of the page the content auto load from database. The only problem is that how i can check that user's reach at the end of the page with in iframe.
I have used auto load content in websites but i only want to know how we can acheive this within iframe because there is no scroll bar in facbook app.
As a Canvas app runs within an iframe it does not have access to window.innerHeight and window.innerWidth. This method exists to provide access to the client (browser) dimensions as well as the current scroll position and offset coordinates.
