在JavaScript中顯示數組數據

Question

我有一個看起來像這樣的JavaScript代碼

 var startdate = "06/10/2014";
            //var newdate = new Date();
            var num = 12
            var months = [];
            for (var a = 0; a < num; a++) {
                var dt = new Date(startdate);
                dt.setMonth(dt.getMonth() - a);
                months[a] = dt;
            }
            return months;

             arylist = arylist + '{';

             arylist = arylist + '"name" :"' + months + '",';

             arylist = arylist + '"st_time_am_pm" :"' + st_time_am_pm + '",';
            arylist = arylist + '"ed_time_am_pm" :"' + ed_time_am_pm + '",';

            arylist = arylist + '}]';

for循環會根據插入的日期恢復12個月前的相同數據。 我想將所有結果顯示在'"name" :"' + months + '",在這里，它將顯示在清單中。 但這只是通過了這一部分。我不知道問題出在哪里。 任何幫助表示贊賞。 謝謝

嘗試這個：

var startdate = "06/10/2014";
        //var newdate = new Date();
        var num = 12
        var months = [];
        var dt = new Date(startdate);
        for (var a = 0; a < num; a++) {
            dt.setMonth(dt.getMonth() - a);
            months[a] = dt;
        }

         arylist = arylist + '{';

         arylist = arylist + '"name" :"' + months + '",';

         arylist = arylist + '"st_time_am_pm" :"' + st_time_am_pm + '",';
        arylist = arylist + '"ed_time_am_pm" :"' + ed_time_am_pm + '",';

        arylist = arylist + '}]';

        return months;
