大量数据查询进度等待

主要代码，请根据实际情况修改。

        Response.Write("<div id='mydiv' >");
        Response.Write("_");
        Response.Write("</div>");
        Response.Write("<script>mydiv.innerText = '';</script>");
        Response.Write("<script language=javascript>;");
        Response.Write("var dots = 0;var dotmax = 10;function ShowWait()");
        Response.Write("{var output; output = '正在查询，请稍后';dots++;if(dots>=dotmax)dots=1;");
        Response.Write("for(var x = 0;x < dots;x++){output += '·';}mydiv.innerText =  output;}");
        Response.Write("function StartShowWait(){mydiv.style.visibility = 'visible'; ");
        Response.Write("window.setInterval('ShowWait()',1000);}");
        Response.Write("function HideWait(){mydiv.style.visibility='hidden';");
        Response.Write("window.clearInterval();}");
        Response.Write("StartShowWait();</script>");
        Response.Flush();
        Thread.Sleep(10000);

另外需要加入添加线程的命名空间using System.Threading;
