前台代码：
<asp:Button ID="Button1" runat="server" Text="打印" onclick="Button1_Click" OnClientClick="this.value='数据提交中……';this.disabled=true;" UseSubmitBehavior="False" /></div>
后台代码：
public partial class WebForm1 : System.Web.UI.Page
{
protected override void OnLoad(EventArgs e)
{
StringBuilder pageBase_script = new StringBuilder("<script Language=\"Javascript\">");
pageBase_script.Append(@"var times=0;
function pageBase_tick() //用于显示执行的时长
{
times++;
var str = '';
var temp = times%5;
for(var i=0;i<temp;i++)
str+='．';
document.getElementById('pageBase_Clocktimes').innerHTML ='正在提交,请稍候'+ str;
} "
);
pageBase_script.Append("<").Append("/").Append("script>");
StringBuilder pageBase_div = new StringBuilder(" <div id=\"pageBase_runing\" runat=\"server\" style=\"z-index: 12000; left: 0px; width: 100%; position: absolute; top: 0px; height: 100%\">");
