对于加载时间比较长的ASP.NET页面,我们可以在客户端浏览器中显示进度条来显示页面正在装载。下面就是具体的实现过程: 1.新建项目,名字为WebPortal,在项目类型中选择Visual C#项目或者Visual Basic项目都可; 2.在模板类型中选择ASP.NET Web应用程序; 3.位置里输入:http://localhost/WebPortal; 4.添加新项:名字为ShowProgress的Web窗体。 5.在您的Web窗体ShowProgress.aspx上添加任何其他的Web服务器控件。 6.在ShowProgress.aspx上单击右键,点“查看代码”,在最上面输入: Visual C# .NET代码 using System.Threading; Visual Basic .NET代码 Imports System.Threading 7.在Page_Load事件里输入: Visual C# .NET代码 Response.Write("<div id='mydiv' >"); Response.Write("_"); Response.Write("</div>"); Response.Write("<script>mydiv.innerText = '';</script>"); Response.Write("<script language=javascript>;"); Response.Write("var dots = 0;var dotmax = 10;function ShowWait()"); Response.Write("{var output; output = '正在装载页面';dots++;if(dots>=dotmax)dots=1;"); Response.Write("for(var x = 0;x < dots;x++){output += '·';}mydiv.innerText = output;}"); Response.Write("function StartShowWait(){mydiv.style.visibility = 'visible'; "); Response.Write("window.setInterval('ShowWait()',1000);}"); Response.Write("function HideWait(){mydiv.style.visibility = 'hidden';"); Response.Write("window.clearInterval();}"); Response.Write("StartShowWait();</script>"); Response.Flush(); Thread.Sleep(10000); Visual Basic .NET代码 Response.Write("<div id='mydiv' >") Response.Write("_") Response.Write("</div>") Response.Write("<script>mydiv.innerText = '';</script>") Response.Write("<script language=javascript>;") Response.Write("var dots = 0;var dotmax = 10;function ShowWait()") Response.Write("{var output; output = '正在装载页面';dots++;if(dots>=dotmax)dots=1;") Response.Write("for(var x = 0;x < dots;x++){output += '·';}mydiv.innerText = output;}") Response.Write("function StartShowWait(){mydiv.style.visibility = 'visible'; ") Response.Write("window.setInterval('ShowWait()',1000);}") Response.Write("function HideWait(){mydiv.style.visibility='hidden';") Response.Write("window.clearInterval();}") Response.Write("StartShowWait();</script>") Response.Flush() Thread.Sleep(10000) 8.在ShowProgress.aspx窗体的html的中输入: <script> HideWait(); </script> 9.点在浏览器中查看即可。 |
