How to detect scroll position of page using jQuery
You can extract the scroll position using jQuery's .scrollTop() method
$(window).scroll(function (event) { var scroll = $(window).scrollTop(); // Do something});
You are looking for the window.scrollTop() function.
$(window).scroll(function() { var height = $(window).scrollTop(); if(height > some_number) { // do something }});

function getData() { $.getJSON('Get/GetData?no=1', function (responseText) { //Load some data from the server })};$(window).scroll(function() { if($(window).scrollTop() + $(window).height() == $(document).height()) { alert("bottom!"); // getData(); }});
