推荐答案

如果您想通过后面的代码访问它，然后

If you want to access it through the code-behind, then

<asp:HiddenField ID="fra1" runat="server" Value="Foo"/>

可以像访问其他任何ASP控件一样进行访问.您甚至可以更改回发的值.

如果使用JavaScript，最好的选择是使用document.getElementById(''elementId'').这是基本的JS方法之一，因此在网络上有很多参考.

can be accessed exactly like any other ASP control. You can even change the value on postbacks.

If you are using JavaScript, your best bet would be to use document.getElementById(''elementId''). This is one of the basic JS methods, so there are lots of references on the web.
