在ASP.NET代码后面访问文档？

Question

If I do this in javascript

document.attributes["Test"] ='1'; 

How can I access that in ASP.NET server side code?

I looked for Attributes on this.Page , but it wasn't there.

Answer 1

Document attributes aren't posted back to the server.

What I do is add a hidden server control, then update that hidden control in javascript. That will be posted back to the server, and can be accessed.

This would be the server control. (note the clientidmode attribute, this is so that I can easily access this control in javascript)

<asp:HiddenField runat="server" ClientIDMode="Static" ID="hdnTest"/>

Then in javascript

document.getElementById("hdnTest").value = '1';

And to access it in the codebehind

hdnTest.Value
