No you cannot get html controls not decorated with runat="server" in code-behind. 不，您无法在代码隐藏中获取未用runat="server"装饰的html控件。
The FindControl method also works for only those controls that are marked runat="server" . FindControl方法也仅适用于标记为runat="server"控件。

I think you can do it by using jquery ajax and webmethod like below 我认为您可以通过使用如下的jquery ajax和webmethod来做到这一点
write in aspx page below code on button click 单击按钮下面的代码在aspx页面中写
<script language="javascript" type="text/javascript">
$(document).ready(function()
{
$("#btnGetHTML").click(function()
{
$.ajax({
url: "YourPAge.aspx/GetHTML",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (data)
{
//You will get html code here
alert("success: " + data.d);
},
failure: function (data)
{
alert("Failure : " + data.d);
},
error: function (data)
{
alert("Error3 : " + data.d);
}
});
}
}
</script>
aspx.cs code aspx.cs代码
[WebMethod]
public static string GetHTML()
{
string html="<html><body></body></html>"
return html;
}

I've always believed it was there more for the understanding that you can mix ASP.NET tags and HTML Tags, and HTML Tags have the option of either being runat="server" or not. 我一直认为，您可以将ASP.NET标记和HTML标记混合使用，而HTML标记则可以选择是否运行runat =“ server”。 It doesn't hurt anything to leave the tag in, and it causes a compiler error to take it out. 将标记保留在其中不会造成任何伤害，并且会导致编译器错误将其取出。 The more things you imply about web language, the less easy it is for a budding programmer to come in and learn it. 您对Web语言所隐含的内容越多，对于一个崭露头角的程序员来说，学习它的难度就越小。 That's as good a reason as any to be verbose about tag attributes. 就像任何关于标签属性的详细说明一样，这也是一个很好的理由。
the importance of is more for consistency and extensibility.
If the developer has to mark some tags (viz. ) for the ASP.NET Engine to ignore, then there's also the potential issue of namespace collisions among tags and future enhancements.
