iPhone and iPad end of scrolling

问题:

I'm making some jQuery cross-browser gallery with infinite scroll i works great but on iPhone (i suppose also on iPad) instead equal values i have some disproportion values don't match

($(window).scrollTop() == ($(document).height() - $(window).height()) 

i just want to reach the end of scrolling on that , after that i could invoke AJAX script, also have to keep in mind that values changing after two fingers wipe zoom.

You need to account for the 60px URL text field on iPhone. Try this:

($(window).scrollTop() + 60 == ($(document).height() - $(window).height())

var wintop = $(window).scrollTop(), docheight = $(document).height(), winheight = $(window).height();
        var  scrolltrigger = 0.90;

        if  ((wintop/(docheight-winheight)) > scrolltrigger) {

            //Your AJAX CALL HERE
        }
    });
