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:
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;
在模板类型中选择ASP.NET Web应用程序;
位置里输入:http://localhost/WebPortal;
添加新项:名字为ShowProgress的Web窗体。
在您的Web窗体ShowProgress.aspx上添加任何其他的Web服务器控件。
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
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=<a href=“http://www.chinaitpower.com/Dev/Programme/Java/index.html“ target=“_blank“>java</a>script>;“);
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=<a href=“http://www.chinaitpower.com/Dev/Programme/Java/index.html“ target=“_blank“>java</a>script>;“)
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)
在ShowProgress.aspx窗体的html的中输入:
<script>
HideWait();
</script>
点在浏览器中查看即可。
