button执行时，提示“请稍后...”页面问题

kehua668 2010-09-08 04:03:02

点击button发送邮件时，页面加载比较慢，固参照例子做了一个提示层，但没能实现，不知问题出在哪？
以下代码：

 <div   id= "esave "  style= "position:absolute;   top:18px;   left:40px;   z-index:10;   visibility:hidden; background-color: #FFCC66;"> 

           <font> 正在操作，请稍候... </font> </div>

    </div> 

...

<asp:Button ID="bt_mail" runat="server" onclick="bt_mail_Click" Text="提交"

                CssClass="btnsubmit" onclientclick="mysub() "  />

function  mysub() 

{ 

esave.style.visibility= "visible "; 



}

function ShowDtsLoading(){ 

	var div = document.createElement("div"); 

	div.id = "oDiv"; 

	div.style.width = document.body.clientWidth; 

	

	div.style.height = document.body.scrollHeight; 

	div.className = "css2"; 

	div.innerHTML = "" +" " +"" +"  " +"<table height='100%' ><tr><td align ='center'  valign ='middle' ><img src='../../images/loading.gif'>"+" <font color='red'>数据正在处理中…… </font></td></tr></table>"; 

	

	document.body.appendChild(div); 

	document.body.style.overflowX="hidden"; 

	document.body.style.overflowY="hidden";

}

在后台添加this.btnDts.Attributes.Add("onclick","ShowDtsLoading();");

<asp:Button ID="Button1" runat="server" Text="Button" Width="143px" OnClick="Button1_Click" />
或使用div显示loading效果
<script language="javascript" type="text/javascript">
document.write(" <div id='loadDiv' style='padding-top: 250px; padding-left: 350px;font-size:x-large;height:400px'> <span id='loading'> <img src=\"../Images/loader2.gif\"/>正在加载数据，请稍候··· </span> </div>");
window.onload = function()
{
document.getElementById("hiddenDiv").style.display="";
document.getElementById("loadDiv").parentNode.removeChild(document.getElementById("loadDiv"));

}
</script>

这时候已经产生回发了吧，当然没用了
将<asp:Button ID="bt_mail" runat="server" onclick="bt_mail_Click" Text="提交"
CssClass="btnsubmit" onclientclick="mysub() " /> 放到AJAX中吧
