對於加載時間比較長的ASP.Net頁面,我們可以在客戶端浏覽器中顯示進度條來顯示頁面正在裝載。下面就是具體的實現過程:
新建項目,名字為WebPortal,在項目類型中選擇Visual C#項目或者Visual Basic項目都可;
在模板類型中選擇ASP.Net Web應用程序;
位置裡輸入:http://localhost/WebPortal;
添加新項:名字為ShowProgress的Web窗體。
在您的Web窗體ShowProgress.ASPx上添加任何其他的Web服務器控件。
在ShowProgress.ASPx上單擊右鍵,點“查看代碼”,在最上面輸入:
Visual C# .Net代碼
using System.Threading;
Visual Basic .Net代碼
Imports System.Threading
在Page_Load事件裡輸入: Visual C# .Net代碼
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 = '正在裝載頁面';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();
