未捕获的ReferenceError：未定义会话 [英] Uncaught ReferenceError: Session is not defined

问题描述

我使用这个下拉菜单

 out.println（< select name = \drplistalbum \onmousedown = \this.value =''; \onchange = \jsFunction（this.value）; \>）; 
 

和我的javascript是

 <   script    类型  ='  text / javascript' < span class =code-keyword>>  
 function jsFunction（value）
 {
 // alert（value）; 
 Session [drpname] = value; 
} 
 <   / script  >  

但我收到错误



未捕获的ReferenceError：未定义会话

解决方案

会话是服务器概念，而不是客户端：会话仅在C＃或VB代码中运行代码背后。会话数据在Javascript中不可用。



我建议如果你在Javascript中需要这种功能，你应该考虑使用cookie。

 <   script     type   =  text / javascript >  
函数SetUserName（）
 {
 var userName =Shekhar Shete ; 
'<％会话[  UserName ] =  '+ userName +'; ％> '; 
 alert（'<％ =会话[  UserName] ％> '）; 
} 
 <   / script  >  

i made a dropdown using this

out.println("<select name=\"drplistalbum\" onmousedown=\"this.value='';\" onchange=\"jsFunction(this.value);\">");

and my javascript is

<script type='text/javascript'>
                 function jsFunction(value)
                 {
       //                      alert(value);
                      Session["drpname"] = value;
                 }
                     </script>

but i get an error

Uncaught ReferenceError: Session is not defined

解决方案

Session is a Server concept, not a Client: the Session is only available within the C# or VB code that runs in the code behind. The Session data is not available in Javascript.

I'd suggest that if you need this kind of function in Javascript, you should look at using cookies instead.

 <script type="text/javascript">
function SetUserName()
{
    var userName = "Shekhar Shete";
    '<%Session["UserName"] = "' + userName + '"; %>';
     alert('<%=Session["UserName"] %>');
}
</script>
