To determine if the document's vertical scroll bar is at the "bottom" of its travel, I've seen this calculation:
delta = $(document).height() - $(window).height(); scrollTopIsAtMax = ($(window).scrollTop() == delta); As the document's scroll bar is scrolled down, the value of $ (window.scrollTop()) increases until it equals the value of delta, signifying the scrollbar is at the bottom end of its travel. Using jquery-nightly.js for June 28/08 with the DOCTYPE in strict mode I get the following when the scrollbar is at the bottom of its travel (all windows maximized): IE7 FFox3 Safari3.1.2(win) Opera9.5 $(document).height() 1170 1015 1006 896 $(window).height() 626 583 634 880 delta 544 432 372 16 $(window).scrollTop() 544 432 372 237 scrollTopIsAtMax true true true false jQuery browser info msie7.0 mozilla1.9 safari525.19 opera9.50 As you can see, this algorithm doesn't work for Opera. Is there a more jQueryesq way to determine when the scrollbar is at its end? Thanks, Bill
