问题描述

嗨

这是我的代码

 FB.Event.subscribe（&＃39 ; auth.statusChange&＃39;，function（response）
 {
  if （response.authResponse）
 {
 
  //  用户已认证您的应用并登录Facebook  
  var  uid =& quot; http： //   graph.facebook.com/" + response.authResponse.userID +& quot; / picture& quot ;;  
 FB.api（&＃39; / me& ＃39;，function（me）{
 
 document.getElementById（auth-displayname;）。innerHTML = me.name; 
 document.getElementById（Email）.innerHTML = me.email; 
 document.getElementById（profileImg&）。src = uid; 
 
  //   document.getElementById（&＃39; testserver&＃39;）。click（）;  
  //   document.getElementById（hdnResultValue）.value = me.name;  
 document.getElementById（testserver&）。click（）; 
 document.getElementById（&＃39;& lt;％= hdnName.ClientID％& gt;&＃39;）。 value  = me.name; 
 document.getElementById（&＃39;& lt;％= hdnEmailAddress.ClientID％& gt;&＃39;）。 value  = me.email; 
 document.getElementById（&＃39; hdnfbid&＃39;）。 value  = me.id; 
 
 
 
}）< /   pre  >  
} 
< pre lang =   xml>< asp：HiddenField ID =   hdnName Value =   0 runat =   server /> 
< asp：HiddenField ID =   hdnEmailAddress Value =   0 runat =  服务器 /> 
< asp：HiddenField ID =   hdnfbid Value =   0 runat =  服务器 /> 
<％ - < asp：HiddenField ID =   hdnResultValue值= < span class =code-string>  0 runat =   server />  -  ％>  
< asp：button runat =   server text =  按钮 id =   testserver OnClick =   fbdetails /> 

aspx.cs页面：

我在中传递值 c＃.net如下所示，但价值没有得到......？请给我回答
 
  protected   void  fbdetails（ object  sender，EventArgs e）
 {
 
  string  codeBehindValue = hdnName.Value; 
  string  codeBehindValue1 = hdnEmailAddress.Value; 
  string  codeBehindValue1 = hdnfbid.Value; 
 
 
} 

解决方案

嘿..

使用HTML输入字段将值从javascript传递到c＃代码后面..

看看下面的示例：

 <  输入    type   =  hidden    id   =  hiddenID    runat   =  server    /  >  

  function  C allMe（）
 {
  document  .getElementById（'  hiddenID'）。value =   OK; 
} 

C＃代码落后：

  protected   void  Page_Load（）
 {
  if （hiddenID.Value ==   OK）
 {
 Response.Write（ 从Javascript传递给Code Behind的值）; 
} 
 
} 

试试吧......

Hi
This is my code

FB.Event.subscribe('auth.statusChange', function (response)
         {
             if (response.authResponse)
            {

                // user has auth'd your app and is logged into Facebook
                var uid = "http://graph.facebook.com/" + response.authResponse.userID + "/picture";
                FB.api('/me', function (me) {

                    document.getElementById(auth-displayname;).innerHTML = me.name;
                    document.getElementById(Email).innerHTML = me.email;
                    document.getElementById(profileImg&).src = uid;

                    //                     document.getElementById('testserver').click();
                    //  document.getElementById(hdnResultValue).value = me.name;
                    document.getElementById(testserver&).click();
                    document.getElementById('<%= hdnName.ClientID %>').value = me.name;
                    document.getElementById('<%= hdnEmailAddress.ClientID %>').value = me.email;
                    document.getElementById('hdnfbid').value = me.id;



                })</pre>
}
<pre lang="xml"><asp:HiddenField ID="hdnName" Value="0" runat="server" />
 <asp:HiddenField ID="hdnEmailAddress" Value="0" runat="server" />
 <asp:HiddenField ID="hdnfbid" Value="0" runat="server" />
  <%--<asp:HiddenField ID="hdnResultValue" Value="0" runat="server" />--%>
     <asp:button runat="server" text="Button" id="testserver" OnClick="fbdetails"/>

aspx.cs page:

I am passing values in c#.net given below but values are not getting...? please give me answer

protected void fbdetails(object sender, EventArgs e)
        {
          
            string codeBehindValue = hdnName.Value;
            string codeBehindValue1 = hdnEmailAddress.Value;
            string codeBehindValue1 = hdnfbid.Value;


        }

解决方案

Hey..
use HTML input field to pass values from javascript to c# code behind..
Have a look at the sample below:

<input type="hidden" id="hiddenID" runat="server" />

function CallMe()
{
document.getElementById('hiddenID').value="OK";
}

C# code behind:

protected void Page_Load()
{
if(hiddenID.Value=="OK")
{
Response.Write("Value passed from Javascript to Code Behind");
}

}

Try it...
