AJAX实例：动态进度条_[AJAX教程]

1.建立进度条html页面

progressbar.htm

2.建立样式common.css.bi-loading-status {}{
/**//*position: absolute;*/
width: 150px;
padding: 1px;
overflow: hidden;
}
.bi-loading-status .text {}{
white-space: nowrap;
overflow: hidden;
width: 100%;
text-overflow: ellipsis;
padding: 1px;
}
.bi-loading-status .progress-bar {}{
border: 1px solid ThreeDShadow;
background: window;
height: 10px;
width: 100%;
padding: 1px;
overflow: hidden;
}
.bi-loading-status .progress-bar div {}{
background: Highlight;
overflow: hidden;
height: 100%;
filter: Alpha(Opacity=0, FinishOpacity=100, Style=1, StartX=0, StartY=0, FinishX=100, FinishY=0);
}
3.建立测试页面
3.1html代码









<%=fixedHeader()%>


3.2cs代码
首先usingusing System.Threading;
using System.IO;
using System.Text;然后添加代码
public class progressbar : System.Web.UI.Page
{
Page_Load#region Page_Load
private void Page_Load(object sender, System.EventArgs e)
{
if(!Page.IsPostBack)
{
string strFileName =Server.MapPath("progressbar.htm" );
StreamReader sr = new StreamReader( strFileName, System.Text.Encoding.Default );
string strHtml = sr.ReadToEnd();
Response.Write( strHtml );
sr.Close();
Response.Flush();
Thread thread = new Thread(new ThreadStart(ThreadProc));
thread.Start();
LoadData();//load数据
thread.Join();
}
}
#endregion

fixedHeader#region fixedHeader
protected string fixedHeader()
{
StringBuilder s=new StringBuilder();
s.Append(@"

s.Append(@"

s.Append(@"

s.Append(@"

s.Append(@"

");
s.Append(@"

for(int m=0;m<100;m++)
{
s.Append(@"

s.Append(@"

s.Append(@"

s.Append(@"

s.Append(@"

}
s.Append(@"

");
return s.ToString();
}
#endregion

ThreadProc#region ThreadProc
private void ThreadProc()
{
string strScript = "";
for ( int i = 0; i <= 100; i++ )
{
System.Threading.Thread.Sleep(10);
Response.Write( string.Format( strScript, i));
Response.Flush();
}
}
#endregion

private void LoadData()
{
for(int m=0;m<90000;m++)

}
}
#endregion
