ASP.NET 进度条(附源代码)

1. 进度条模板文件 ProgressBar.htm

1 <html>
2 <head>
3 <title></title>
4 <script language="javascript">
5 //设置进度条进度
6 function SetPorgressBar(msg, pos)
7 {
8     ProgressBar.style.width= pos + "%";
9     WriteText("Msg1",msg + " 已完成" + pos + "%");
10 }
11
12 //设置进度条完成信息
13 function SetCompleted(msg)
14 {
15     if(msg=="")
16         WriteText("Msg1","完成。");
17     else
18         WriteText("Msg1",msg);
19 }
20
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     }
