前台js
   function lookList(groupid,groupname)
   {
           alert(groupname)
     这里会报错,就这个groupname未定义,这个值从后台传过来.
   var GroupID = groupid.toString();
   location.href ='AddressList.aspx?groupid='+GroupID+'&groupname='+groupname;
 
   }

Answer 1

很明显，返回值只有一个 public string GetGroupList() 
  function lookList(groupid,groupname) //这块确实两个返回值，groupid 有值,groupname 无值
   { 
           alert(groupname) 
     这里会报错,就这个groupname未定义,这个值从后台传过来. 
   var GroupID = groupid.toString(); 
   location.href ='AddressList.aspx?groupid='+GroupID+'&groupname='+groupname; 
  
   }

我前台是DIV.innerHTML = 返回的HTML串了

Answer 3

判断下datatable该字段是否有空值看看，

Answer 4

前台js  
   function GoToEditGroup(groupid,groupname)  
   {  
           alert(groupname)  
     这里会报错,就这个groupname未定义,这个值从后台传过来.  
   var GroupID = groupid.toString();  
   location.href ='AddressList.aspx?groupid='+GroupID+'&groupname='+groupname;  
   
   } 
我前台是DIV.innerHTML = 返回的HTML串了不好意思看错了，你看看html 的源文件如何，一个也可以检查3楼说的，datatable字段是否有值

Answer 5

dataTable 不为空啊,我前台界面上还显示出来了

Answer 6

function GoToEditGroup(groupid,groupname)  
   {  
           alert(groupname.value)  
     这里会报错,就这个groupname未定义,这个值从后台传过来.  
   var GroupID = groupid.toString();  
   location.href ='AddressList.aspx?groupid='+GroupID+'&groupname='+groupname;  
   
   } 

Answer 7

groupname.value 这个值怎是undefined啊
