关于滚动条

 $(window).scroll(function () {



        var wScrollTop = $(window).scrollTop();

        var offsetHeight = 10;

        var docHeight = $(document).height();

        var wHeight = $(window).height();



        //        console.log("wHeight:" + wHeight);

        //        console.log("offsetHeight:" + offsetHeight);

        //        console.log("docHeight:" + docHeight);

        //        console.log("tarHeight:" + tarHeight);



        if (wScrollTop >= docHeight - wHeight) {

            $.mobile.showPageLoadingMsg();



            gobalPage++;

            $.ajax({

                type: "POST",

                url: "http://localhost:58300/handle.aspx",

                data: "fnName=getContentData&author=haoxinqing&page=" + gobalPage,

                dataType: "jsonp",

                jsonpCallback: "hxqContent",

                success: function (msg) {



                    console.log(msg);

                    $.mobile.hidePageLoadingMsg();



                    //$.mobile.changePage($("#main"), "slide");

                    $("#contentList").append(msg.content);

                    $('#contentList').listview('refresh');

                }

            });



        }



        if (wHeight == 0) {

            //javatranster.getlastData();

            //console.log(666);

        }



    });

滚到底部加载，应该一看就明白了，里面几个变量的意思。
