javascript - 尝试迭代 json 字符串

Question

我正在尝试迭代这个 json 编码数组，它是一个字符串:

"{"":{"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 调用返回该字符串，我试图只获取诸如“应用程序使用情况”和“离线计量”之类的键，如下所示:

$.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;
            }
        });

但我无法获得进入问题类别的 key 。

我使用它来设置 highchart 气泡图中的类别，稍后我将使用该字符串中的更多数据。

我需要先让它工作。

问题在于您使用 array.push 的方式。您应该使用 array.push(item) 而不是 array.push = item。
