Question

Even tho. scrollling is “no”, and overflow is hidden, browsers dont show scrolls etc yet I can scroll by middle mouse button. I want user to be unable to scroll no matter what.
Also, the frameset has: rows=”50,*” and the stuff inside frame isnt higher than 50 height px yet again, it is scrollable for few pixels.

In the iframe add this code:

$(document).on('mousewheel keydown', function (event) {

    //if the mousewheel event is being fired or if a keydown event with one of the blacklisted keycodes
    if (event.type == 'mousewheel' || event.which in { 40 : 0, 38 : 0, 104 : 0, 98 : 0, 32 : 0 }) {

        //then prevent the scroll from occuring
        return false;
    }
});​​​

I tried disabling scrolling by returning false for the scroll event but it cannot be disabled in this way (at least in Chrome 18, although I suspect most, if not all, browsers are the same).
