this.Page.Response.Write("<div id='mydiv' >"); 

   this.Page.Response.Write("_"); 

   this.Page.Response.Write("</div>"); 

   this.Page.Response.Write("<script>mydiv.innerText = '';</script>"); 

   this.Page.Response.Write("<script language=javascript>;"); 

   this.Page.Response.Write("var dots = 0;var dotmax = 10;function ShowWait()"); 

   this.Page.Response.Write("{var output; output = '正在查询,请稍后';dots++;if(dots>=dotmax)dots=1;"); 

   this.Page.Response.Write("for(var x = 0;x < dots;x++){output += '·';}mydiv.innerText =  output;}"); 

   this.Page.Response.Write("function StartShowWait(){mydiv.style.visibility = 'visible'; "); 

   this.Page.Response.Write("window.setInterval('ShowWait()',1000);}"); 

   this.Page.Response.Write("function HideWait(){mydiv.style.visibility = 'hidden';"); 

   this.Page.Response.Write("window.clearInterval();}");
