Response.Write("<script language=JavaScript>");
Response.Write("var dots = 0;var dotmax = 10;function ShowWait()");
Response.Write("{var output; output = '正在装载页面';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);
