7 {
8 ProgressBar.style.width= pos + "%";
9 WriteText("Msg1",msg + " 已完成" + pos + "%");
10 }

13 function SetCompleted(msg)
14 {
15 if(msg=="")
16 WriteText("Msg1","完成。");
17 else
18 WriteText("Msg1",msg);
19 }

21 // 更新文本显示信息
22 function WriteText(id, str)
23 {
24 var strTag = '<font face="Verdana, Arial, Helvetica" size="2" color="#ea9b02"><B>' + str + '</B></font>';
25 if (document.all) document.all[id].innerHTML = strTag;
26 }
27 </script>
28 </head>
29 <body>
30 <div id="Msg1"><font face="Verdana, Arial, Helvetica" size="2" color="#ea9b02"><b>正在加载</b></font></div>
31 <div id="ProgressBarSide" style="color:Silver;border-width:1px;border-style:Solid;width:300px;">
32 <div id="ProgressBar" style="background-color:#3366FF; height:21px; width:0%;"></div>
33 </div>
34 </body>
35 </html>2. Default.aspx.cs
1 protected void Page_Load(object sender, EventArgs e)
2 {
3 // 根据 ProgressBar.htm 显示进度条界面
4 string templateFileName = Path.Combine(Server.MapPath("."), "ProgressBar.htm");
5 StreamReader reader = new StreamReader(@templateFileName,System.Text.Encoding.GetEncoding("gb2312"));
6 string html = reader.ReadToEnd();
7 reader.Close();
8 Response.Write(html);
9 Response.Flush();
10 System.Threading.Thread.Sleep(200);
11
12 // 根据处理任务处理情况更新进度条
13 string jsBlock;
14 for (int i = 1; i <= 100; i++)
15 {
16 System.Threading.Thread.Sleep(10);
17 jsBlock = "<script>SetPorgressBar('" + "A" + i.ToString() + "','" + i.ToString() + "'); </script>";
18
19 Response.Write(jsBlock);
20 Response.Flush();
21 }
22
23 // 处理完成
24 jsBlock = "<script>SetCompleted('处理完成。'); </script>";
25 Response.Write(jsBlock);
26 Response.Flush();
27 }
