Question

有一个没有任何错误的ASP页面，但是在页面加载后页面呈现为空白页面。但是，如果我复制生成的代码，并将其放入另一个ASP页面并加载该页面，它就会很好地渲染。这几乎就像我需要在代码末尾的东西说现在你已经完成运行代码显示生成的html。

Answer 1

您无法以有效的方式创建服务器控件。 <asp:TreeNode>控件不是实际的html元素，所以即使它被推送到客户端，也不会实际显示任何内容。

Answer 2

Response.Write适用于调试，但对实际生产不利。您永远不知道何时获得所需的输出。我曾经设法让我的头部在页面的 end 而不是顶部呈现。

将HTML代码移出Response.Write部分，并在需要实际HTML的地方使用纯HTML。所以，而不是：

Response.Write("<!DOCTYPE html>" + System.Environment.NewLine);

Response.Write("<html lang=\"en\" xmlns=\"http://www.w3.org/1999/xhtml\">" + System.Environment.NewLine);

使用它：

%>
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

只在实际需要的地方切换到编码。

Answer 3

我认为你不能写出如下行：

Response.Write("<asp:TreeNode Value=\"" + tempArray[8] + "\" Text=\"" + tempArray[4] + "\" NavigateUrl=\"CapitalText.aspx?CID=" + tempArray[8] + "\" Target=\"frame_main\"></asp:TreeNode>" + System.Environment.NewLine);

Response.Write写入响应流，写入的任何内容都将按原样发送到客户端浏览器。由于asp：TreeNode（或应在服务器上处理的任何其他指令）无效html，因此无法获得预期结果。

处理任何asp：*或runat =“server”（在服务器上）并转换为有效的HTML，此HTML将发送到客户端浏览器。

ASP不渲染生成页面
