根据滚动条动态加载内容显示的jQuery代码

滚动条滚动到页面底部附近时动态加载内容显示

var loading = false;
$(window).scroll(function(){
    if((($(window).scrollTop()+$(window).height())+250)>=$(document).height()){
        if(loading == false){
            loading = true;
            $('#loadingbar').css("display","block");
            $.get("load.php?start="+$('#loaded_max').val(), function(loaded){
                $('body').append(loaded);
                $('#loaded_max').val(parseInt($('#loaded_max').val())+50);
                $('#loadingbar').css("display","none");
                loading = false;
            });
        }
    }
});
 
// Update code, simple add or integrate this.
$(document).ready(function() {
    $('#loaded_max').val(50);
});
