JAVASCRIPT读取本地ASP.NET页面问题
只想读取一个Test.aspx页面,把.aspx页面的源代码(包括服务器端的任何控件)
Test.aspx源代码如下:
/****************************************************************
<%@ Page language= "c# " Codebehind= "Test.aspx.cs " AutoEventWireup= "false " Inherits= "UserPopedom.Web.NavigationMenu.Test " %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN " >
<HTML>
<HEAD>
<title> Test </title>
<meta name= "GENERATOR " Content= "Microsoft Visual Studio .NET 7.1 ">
<meta name= "CODE_LANGUAGE " Content= "C# ">
<meta name= "vs_defaultClientScript " content= "JavaScript ">
<meta name= "vs_targetSchema " content= "http://schemas.microsoft.com/intellisense/ie5 ">
</HEAD>
<body MS_POSITIONING= "GridLayout ">
<form id= "Form1 " method= "post " runat= "server ">
<asp:DataGrid id= "DataGrid1 " style= "Z-INDEX: 101; LEFT: 216px; POSITION: absolute; TOP: 112px "
runat= "server "> </asp:DataGrid>
</form>
</body>
</HTML>
*****************************************************************/
在HTML中JAVASCRIPT可以读出来
显示的内容跟上面的代码一样的；
问题是同样的代码放在.aspx中去处理
就会显示其生成后的源代码：
显示的内容如下:
/*****************************************************************
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN " >
<HTML>
<HEAD>
<title> Test </title>
<meta name= "GENERATOR " Content= "Microsoft Visual Studio .NET 7.1 ">
<meta name= "CODE_LANGUAGE " Content= "C# ">
<meta name= "vs_defaultClientScript " content= "JavaScript ">
<meta name= "vs_targetSchema " content= "http://schemas.microsoft.com/intellisense/ie5 ">
</HEAD>
<body MS_POSITIONING= "GridLayout ">
<form name= "Form1 " method= "post " action= "Test.aspx " id= "Form1 ">
<input type= "hidden " name= "__VIEWSTATE " value= "dDwtNTcyNzE4MDk2O3Q8O2w8aTwxPjs+O2w8dDw7bDxpPDE+Oz47bDx0PEAwPDs7Ozs7Ozs7Ozs+Ozs+Oz4+Oz4+Oz4vNOdKYRmg/fxi8tmIBO7mVPf9RA== " />
</form>
</body>
</HTML>

如何在.aspx中获取Test.aspx的源代码呢?????????????
或者知道为什么的告诉一下：
谢谢
[解决办法]
JAVASCRIPT客户端读取肯定就是aspx在客户端生成的html代码啊。

我的观点:
我想应该获取的是生成后的源码
因为你的Test.aspx是在URL中的，这样好像只能获取生成后的源码
至于你的Html获取到的源码，那只是一个文件，
获取URL中的源码和获取文件的内容是两个概念，
