私は文字列である。このJSONエンコードされた配列を反復処理しようとしている

Question

：

"{"":{"count":{"total":112,"open":0, 
"solved":0, 
"deleted":106, 
"closed":6}, 
"average_time_open_in_minutes":206, 
"tickets_fortnight_week_count":11, 
"tickets_last_week_count":15,"trend":1}, 
"Net2grid":{"count":"total":8,"open":0,"solved":0,"deleted":8},"average_time_open_in_minutes":0,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Closed_by_merge":{"count":{"total":2,"open":0,"solved":0,"closed":2},"average_time_open_in_minutes":502,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Analytics":{"count":{"total":1,"open":0,"solved":0,"deleted":1},"average_time_open_in_minutes":26,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Meter":{"count":{"total":5,"open":5,"solved":0},"average_time_open_in_minutes":0,"tickets_fortnight_week_count":0,"tickets_last_week_count":2,"trend":1},"Installation":{"count":{"total":8,"open":5,"solved":3},"average_time_open_in_minutes":404,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Other...":{"count":{"total":3,"open":2,"solved":1},"average_time_open_in_minutes":39,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Meter Offline":{"count":{"total":8,"open":7,"solved":1},"average_time_open_in_minutes":8,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"App Usage":{"count":{"total":6,"open":5,"solved":0,"deleted":1},"average_time_open_in_minutes":8,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0}}" 

AJAX呼び出しは、その文字列を返し、私はキーのみを同様に取得しようとしています：そのように戻るには、「アプリの使用状況」と「メーターオフライン」：

$.get('/ajax/ticket-and-notes-data.php', function (data) { 

      var problems = getProblems(data); 

      function getProblems(problems) { 
       var problemCategories = []; 
       $.each(JSON.parse(problems), function (key, value) { 
        if (key != "") { 
         problemCategories.push = key; 
        } 
       }); 
       return problemCategories; 
      } 
     }); 

しかし、私はキーがproblemCategoriesに行くために取得することはできません。

これを使用してハイチャートのバブルチャートのカテゴリを設定し、後でその文字列のデータをさらに使用します。

私はこれを最初に動作させる必要があります。

問題はあなたがarray.pushを使用している方法です。 array.push = itemの代わりにarray.push(item)を使用してください。
