JSONから取得した変数を割り当てます

Question

私は盲目ですか？なぜ私はこれを変数「進捗状況」に入れることができないのですか？ これは文字列として保存されず、 'obj.songProgress [i] .songProgress'がコンソールに出力されますが、それ自体の進捗状況は表示されません。変数はさらに上に割り当てられています。ここで

$(document).on("click",".profTemp", function() 
      {  

       if(!$(this).hasClass('selected')) 
       { 

       var selectedUser; 
       var previous = null; 
       var current = null; 
       var assigned = false; 
       var currentSong; 
       var previousSong; 
       var previousUser = null; 

       selectedUser = $(this).children('span').text(); 
       selectedUser = selectedUser.trim(); 

       $('.profTemp').removeClass('selected'); 
       clearInterval(pollUser); 

       $(this).toggleClass('selected'); 

       pollUser = setInterval(function() 
       { 
        console.log(selectedUser); 
        $.ajax({ 
        url: '/getJSON', 
        dataType: 'json', 
        success: function(response) { 
         obj = JSON.parse(response); 
         var changeTo; 
         var deviceID; 
         var playing; 
         var progress; 


         for(var i = 0; i < obj.clients.length; i++) 
         { 
          if(selectedUser == obj.clients[i].userName) 
          { 
          console.log(selectedUser + " inside if"); 
          current = JSON.stringify(obj.clients[i]); 
          changeTo = obj.clients[i].uri; 
          device = obj.clients[i].deviceID 
          playing = obj.clients[i].isPlaying; 
          currentSong = obj.clients[i].songName;          
          } 
         } 

         for(var i = 0; i < obj.songProgress.length; i++) 
          { 
          if(selectedUser == obj.songProgress[i].userName) 
          { 
           progress = obj.songProgress[i].songProgress; 
           console.log(obj.songProgress[i].songProgress + progress); 
          }        
          } 

はJSONです：

Answer 1

はconsole.log（obj.songProgress [i]が.songProgress +進捗状況）。 上記の状態はデータを合計し、合計データを提供しています。

if(selectedUser == obj.songProgress[i].userName) 
    { 
    progress = obj.songProgress[i].songProgress; 
    console.log(obj.songProgress[i].songProgress, progress); 
    }
