终于找到一个ASPNET实现进度条的例子
建立一个WEB工程添加新项>HTML页面命名为内容如下
<!DOCTYPE html PUBLIC //WC//DTD XHTML Transitional//EN transitionaldtd>
<html xmlns= id=mainWindow>
<head>
<title>无标题页</title>
<script language=javascript>
function SetPorgressBar(pos)
{
//设置进度条居中
var screenHeight = window[mainWindow]offsetHeight;
var screenWidth = window[mainWindow]offsetWidth;
ProgressBarSidestylewidth = Mathround(screenWidth / );
ProgressBarSidestyleleft = Mathround(screenWidth / );
ProgressBarSidestyletop = Mathround(screenHeight / );
ProgressBarSidestyleheight = px;
ProgressBarSidestyledisplay = ;
//设置进度条百分比
ProgressBarstylewidth = pos + %;
ProgressTextinnerHTML = pos + %;
}
//完成后隐藏进度条
function SetCompleted()
{
ProgressBarSidestyledisplay = none;
}
</script>
</head>
<body>
<div id=ProgressBarSide >
<div id=ProgressBar ></div>
<div id=ProgressText ></div>
</div>
</body>
</html>
后台代码Defaultaspxcs
using System;
using SystemData;
using SystemConfiguration;
using SystemWeb;
using SystemWebSecurity;
using SystemWebUI;
using SystemWebUIWebControls;
using SystemWebUIWebControlsWebParts;
using SystemWebUIHtmlControls;
using SystemThreading;
using SystemIO;
public partial class _Default : SystemWebUIPage
{
private void beginProgress()
{
//根据显示进度条界面
string templateFileName = PathCombine(ServerMapPath() );
StreamReader reader = new StreamReader(@templateFileNameSystemTextEncodingGetEncoding(GB));
string html = readerReadToEnd();
readerClose();
ResponseWrite(html);
ResponseFlush();
}
private void setProgress(int percent)
{
string jsBlock = <script>SetPorgressBar( + percentToString() + ); </script>;
ResponseWrite(jsBlock);
ResponseFlush();
}
private void finishProgress()
{
string jsBlock = <script>SetCompleted();</script>;
ResponseWrite(jsBlock);
ResponseFlush();
}
private void Page_Load(object sender SystemEventArgs e)
{
beginProgress();
for (int i = ; i <= ; i++)
{
setProgress(i);
//此处用线程休眠代替实际的操作如加载数据等
SystemThreadingThreadSleep();
}
finishProgress();
}
}
