ASP.net页面局部刷新

Question

我想实现一个滚动条随数据库数据变化自己实时刷新，没有点击事件，怎么解决？？求解<span style = "color : red"><asp:Label id="count" runat="server"/></span><br />
      <li><span style = "color : red"><asp:Label id="Label1" runat="server"/></span></li>
  <li> <input id ="warning" runat="server" type="hidden" name="FunName"/> </li>
         <li><span style ="color : red"><script language="javascript" type="text/javascript">
                                                        var marqueeContent = new Array();   //滚动主题
                                                        var warningstr = $("#warning").val();
                                                        var strzero = "0000000000";
                                                        var strRows1Id = warningstr.split(',');
                                                        if (strRows1Id.length == 1 || strRows1Id.length == 0) {                                                            marqueeContent[0] = "预警提示：暂无预警";
                                                        } else { for (i = 0; i < strRows1Id.length - 1; i++) { marqueeContent[i] = "预警提示：煎药单号为" + strzero.substring(0, 10 - strRows1Id[i].length) + strRows1Id[i] + "" + "已过发货预警时间";
    }
   }
                                                       var marqueeInterval = new Array();  //定义一些常用而且要经常用到的变量
                                                        var marqueeId = 0;

                                                            marqueeId++;
                                                            marqueeInterval[0] = setInterval("startMarquee()", marqueeDelay);
                                                        }
                                                        function startMarquee() {
                                                            var str = marqueeContent[marqueeId];
                                                            marqueeId++;
                                                            if (marqueeId >= marqueeContent.length) marqueeId = 0;
                                                            if (marqueeBox.childNodes.length == 1) {
                                                                var nextLine = document.createElement('DIV');

Answer 1

你这代码格式贴得简直不能直视会ajax不？会的话就轮询每隔几秒几分钟（根据自身情况定）去取一次数据库的最新值，不会的话就去学。要是觉得轮询太low，用SignalR

Answer 2

setInterval(refresh,1000);//每一秒执行一个函数function refresh(){
    $.ajax()...
}

Answer 3

asp.net 可以判断是否到了最后，如果是就再加载数据

Answer 4

就是类似于 ，手机上的滑动加载是吧？别忘了引用jquery类库
[JavaScript] 纯文本查看 复制代码
    $(window).scroll(function () {
        var scrollTop = $(this).scrollTop();
        var scrollHeight = $(document).height();
        var windowHeight = $(this).height();
        if (scrollTop + windowHeight == scrollHeight) {      //此处是滚动条到底部时候触发的事件，在这里写要加载的数据，或者是拉动滚动条的操作//var page = Number($("#redgiftNextPage").attr('currentpage')) + 1;
//redgiftList(page);
//$("#redgiftNextPage").attr('currentpage', page + 1);        }
    });

Answer 5

$("body").scroll(function() {
       ajax()
});获取到页面的滚动条滚动事件，然后去ajax请求后台做实时刷新
