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!!!

$.ajax({
url:
onsuccess:function(data){ $("#divxxxx").html(data);}
})
差不多是这样的一个方法
导入的时候div或什么标签的先显示loading
完成的时候就会实现innerhtml的效果
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>");
}
/// <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("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();
}
html里写:window.onload = remove_loading();
怎么可以设置时间列。
在ajax 的 beforeSend中写个div就可以了
type: "POST",
url: "DefectDisposition.axd",
data: "flag=GetDefectDistributeByPhase&version=" + Config.RdmVersion + "&domain=" + escape('软件') + "&serial=" + new Date().getTime(),
dataType: "json",
async: false,
beforeSend: function() {//发送消息前
QualityPublicMethod.Clear();
}, error: function(txt) {
Config.IsQualityNeedRequestDataIng = false;
},
success: function(txt) {
