ASP.net页面局部刷新

[慢慢非]

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;
var marqueeDelay = 4000;
var marqueeHeight = 15;
function initMarquee() {
var str = marqueeContent[0];
document.write('<div id=marqueeBox style="overflow:hidden;height:' + marqueeHeight + 'px" onmouseover="clearInterval(marqueeInterval[0])" onmouseout="marqueeInterval[0]=setInterval(\'startMarquee()\',marqueeDelay)"><div>' + str + '</div></div>');
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');
nextLine.innerHTML = str;
marqueeBox.appendChild(nextLine);
}
else {
marqueeBox.childNodes[0].innerHTML = str;
marqueeBox.appendChild(marqueeBox.childNodes[0]);
marqueeBox.scrollTop = 0;
}
clearInterval(marqueeInterval[1]);
marqueeInterval[1] = setInterval("scrollMarquee()", 10);
}
function scrollMarquee() {
marqueeBox.scrollTop++;
if (marqueeBox.scrollTop % marqueeHeight == marqueeHeight) {
clearInterval(marqueeInterval[1]);
}
}
initMarquee();
</script></span></li>

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

[全栈极简]

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

[代码之城]

asp.net 可以判断是否到了最后，如果是就再加载数据

[正怒月神]

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);

        }
    });

$("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
