祈求帮助呀。。。大侠帮忙啊！！！
我在网上找了很多方法和代码，为什么没有一个可用的。都不能理想。
我要的效果就是：asp.net里面有大量的数据，再空白页面的时候显示“数据导入中”或“请等待”，最好是等待图片，当页面导入完成，等待标志消失。相信大家都见过。
希望大家帮忙，给一个页面改动小的方法，因为网站已经成形。最好是js的，如果ajax的修改不大的也行。
希望大侠给一个可行的例子。最好您测试通过的，因为我找个很久，没有找到能用（可能是我不会用，嘿嘿）！
谢谢，谢谢！！！

我可以给你一个提交按钮编程等待的例子。就想csdn留言是的【提交回复】效果一样，你看看有用不
public void page_load(Object obj, EventArgs e)
{
btn.Attributes.Add("onclick","state=true;");
StringBuilder sb=new StringBuilder();
sb.Append("if (!state) return;");
sb.Append("var button=document.getElementById('btn');");
sb.Append("button.value=' Please Wait... ';");
sb.Append("document.body.style.cursor='wait';");
sb.Append("button.disabled=true;");
string strScript="<script>";
strScript=strScript +"var state=false;";
//将函数绑定到页面的onbeforeunload事件:
strScript=strScript +"window.attachEvent('onbeforeunload',function(){" +sb.ToString()+ "});";
strScript=strScript +"</"+"script>";
Page.RegisterStartupScript("onbeforeunload",strScript);
}
protected void Submit_Click(object sender, EventArgs e)
{
//模拟长时间的按钮处理
System.Threading.Thread.Sleep(2000);
Response.Write("<script>alert('保存成功！');" + "</" + "script>");
}

page_load中写init();
- C# code
/// <summary>页面加载中效果</summary> /// <returns></returns> public static void init() { HttpContext.Current.Response.Write(" <script language=JavaScript type=text/javascript>"); HttpContext.Current.Response.Write("var t_id = setInterval(animate,20);"); HttpContext.Current.Response.Write("var pos=0;var dir=2;var len=0;"); HttpContext.Current.Response.Write("function animate(){"); HttpContext.Current.Response.Write("var elem = document.getElementById('progress');"); HttpContext.Current.Response.Write("if(elem != null) {"); HttpContext.Current.Response.Write("if (pos==0) len += dir;"); HttpContext.Current.Response.Write("if (len>32 || pos>79) pos += dir;"); HttpContext.Current.Response.Write("if (pos>79) len -= dir;"); HttpContext.Current.Response.Write(" if (pos>79 && len==0) pos=0;"); HttpContext.Current.Response.Write("elem.style.left = pos;"); HttpContext.Current.Response.Write("elem.style.width = len;"); HttpContext.Current.Response.Write("}}"); HttpContext.Current.Response.Write("function remove_loading() {"); HttpContext.Current.Response.Write(" this.clearInterval(t_id);"); HttpContext.Current.Response.Write("var targelem = document.getElementById('loader_container');"); HttpContext.Current.Response.Write("targelem.style.display='none';"); HttpContext.Current.Response.Write("targelem.style.visibility='hidden';"); HttpContext.Current.Response.Write("}"); HttpContext.Current.Response.Write("</script>"); HttpContext.Current.Response.Write("<style>"); HttpContext.Current.Response.Write("#loader_container {text-align:center; position:absolute; top:1%; width:100%; left: 0;}"); HttpContext.Current.Response.Write("#loader {font-family:Tahoma, Helvetica, sans; font-size:11.5px; color:#000000; background-color:#FFFFFF; padding:10px 0 16px 0; margin:0 auto; display:block; width:130px; border:1px solid #5a667b; text-align:left; z-index:2;}"); HttpContext.Current.Response.Write("#progress {height:5px; font-size:1px; width:1px; position:relative; top:1px; left:0px; background-color:#8894a8;}"); HttpContext.Current.Response.Write("#loader_bg {background-color:#e4e7eb; position:relative; top:8px; left:8px; height:7px; width:113px; font-size:1px;}"); HttpContext.Current.Response.Write("</style>"); HttpContext.Current.Response.Write("<div id=loader_container>"); HttpContext.Current.Response.Write("<div id=loader>"); HttpContext.Current.Response.Write("<div align=center>页面正在加载中 ...</div>"); HttpContext.Current.Response.Write("<div id=loader_bg><div id=progress> </div></div>"); HttpContext.Current.Response.Write("</div></div>"); HttpContext.Current.Response.Flush(); }
