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。
