我需要在c＃中获取代码背后的javascript值。我知道我可以使用隐藏字段，但页面上没有用于回发的服务器控件。请告诉我如何在代码中获取代码。
I need to get javascript values on code behind in c#.I know i can use hidden field but there is no server control on page for postback.Please tell me how can get vales in code behind.
这是我的代码：
<html> <head> <title>Facebook Get Logged in User Details UserName,Email,Profile Image</title> <script src="jquery-1.6.2.min.js" type="text/javascript"></script> <script type="text/javascript" src="code.jquery/jquery-latest.js"></script> </head> <body> <script> // Load the SDK Asynchronously (function (d) { var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) { return; } js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook/en_US/all.js"; ref.parentNode.insertBefore(js, ref); } (document)); // Init the SDK upon load window.fbAsyncInit = function () { FB.init({ appId: 'APPID', // App ID channelUrl: '//' + window.location.hostname + '/channel', // Path to your Channel File status: true, // check login status cookie: true, // enable cookies to allow the server to access the session xfbml: true // parse XFBML }); // listen for and handle auth.statusChange events FB.Event.subscribe('auth.statusChange', function (response) { if (response.authResponse) { // user has auth'd your app and is logged into Facebook var uid = "graph.facebook/" + response.authResponse.userID + "/picture"; FB.api('/me', function (me) { document.getElementById('auth-displayname').innerHTML = me.name; document.getElementById('myJSString').value = me.name; alert(document.getElementById('myJSString').value); document.getElementById('Email').innerHTML = me.email; document.getElementById('profileImg').src = uid; // document.getElementById('ctl00_CPHDefault_tcTPS_TPProd_ctl01_tcProduction_TPNewTitlesStatus_ChangedRowsIndicesHiddenField').value = uid; // alert('yyy'); }) document.getElementById('auth-loggedout').style.display = 'none'; document.getElementById('auth-loggedin').style.display = 'block'; } else { // user has not auth'd your app, or is not logged into Facebook document.getElementById('auth-loggedout').style.display = 'block'; document.getElementById('auth-loggedin').style.display = 'none'; } }); $("#auth-logoutlink").click(function () { FB.logout(function () { window.location.reload(); }); }); } </script> <h1> Facebook Login Authentication Example</h1> <div id="auth-status"> <div id="auth-loggedout"> <div id="Result" class="fb-login-button" autologoutlink="true" scope="email,user_checkins">Login</div> </div> <div id="auth-loggedin" style="display: none"> Name: <b><span id="auth-displayname"></span></b>(<a href="#" id="auth-logoutlink">logout</a>)<br /> Email: <b><span id="Email"></span></b><br /> Profile Image: <img id="profileImg" /> <form runat="server"> <asp:HiddenField runat="server" id="myJSString" /> </form> </div> </div> </body> </html>你可以看到没有服务器控件，所以我怎么能在后面的代码中获取NAME，UID变量。
You can see there is no server control so how i can get NAME,UID variables in code behind.
谢谢
推荐答案我会研究使用ASP.NET AJAX页面方法，因为它们允许生活在 .aspx 页面中的脚本可调用的独立Web服务，如下所示：
I would investigate the use of ASP.NET AJAX Page Methods, because they allow for script callable stand-alone web services that live in an .aspx page, like this:
代码隐藏文件中的页面方法（出于讨论的目的将其命名为default.aspx）：
Page Method in your code-behind file (call it default.aspx for discussion's sake):
[WebMethod] public static string SaveData(string name, string uid) { // Logic here to do what you want with name and uid values (i.e. save to database, call another service, etc.) }jQuery调用default.aspx的SaveData方法：
jQuery call to default.aspx's SaveData method:
$.ajax({ type: "POST", url: "default.aspx/SaveData", data: "{'name':'John', 'uid':'ABC123'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { // Do something interesting here. } });注意：ASP.NET AJAX页面方法自动将其响应编码为 JSON 所以你不会在代码隐藏或任何序列化逻辑中看到任何 JSON 序列化。
Notes: ASP.NET AJAX Page Methods automatically encode their response to JSON so you will not see any JSON serialization in the code-behind or any serialization logic at all.
