【问题描述】：

我有一个来自远程 api 的 json 响应。在那个 JSON 中，我有一个 l2_list，它描述了各个孩子的排序顺序。

我想根据“l2_list”顺序对子项进行排序。

我有一个 json 数组，如下所示：

var TreeObj = `{
    "RULE_JSON":
        {

            "2674":{
                "pid":"0",
                "level":"1",
                "mid":"2674",
                "name":"test1",
                "l2_list": [3083],
                "children":
                    {
                        "3083":{"pid":"2674","level":"2","mid":"3083","name":"MAINTENANCE","children":[]}
                    }
            },
            "2619":{
                "pid":"0",
                "level":"1",
                "mid":"2619",
                "name":"EFFICIENCY",
                "l2_list": [2605,2608,2607,2626,2627,3057,3058],
                "children":
                    {
                        "2605":{"pid":"2619","level":"2","mid":"2605","name":"IDLING","children":[]},
                        "2607":{"pid":"2619","level":"2","mid":"2607","name":"COMPLIANT","children":[]},
                        "2626":{"pid":"2619","level":"2","mid":"2626","name":"DISPATCHED","children":[]},
                        "2627":{"pid":"2619","level":"2","mid":"2627","name":"HOURS","children":[]},
                        "2608":{"pid":"2619","level":"2","mid":"2608","name":"COMPLIANT DEPART","children":[]},
                        "3058":{"pid":"2619","level":"2","mid":"3058","name":"CENTER VISITS","children":[]},
                        "3057":{"pid":"2619","level":"2","mid":"3057","name":"OFFICE VISITS","children":[]}
                    }
            }
        }
}`;

排序后，我的结果集应该显示 2619 个孩子，如下所示：

"l2_list": [2605,2608,2607,2626,2627,3057,3058],
    "children":
        {
            "2605":{"pid":"2619","level":"2","mid":"2605","name":"IDLING","children":[]},
            "2608":{"pid":"2619","level":"2","mid":"2608","name":"COMPLIANT DEPART","children":[]},
            "2607":{"pid":"2619","level":"2","mid":"2607","name":"COMPLIANT","children":[]},
            "2626":{"pid":"2619","level":"2","mid":"2626","name":"DISPATCHED","children":[]},
            "2627":{"pid":"2619","level":"2","mid":"2627","name":"HOURS","children":[]},
            "3057":{"pid":"2619","level":"2","mid":"3057","name":"OFFICE VISITS","children":[]},
            "3058":{"pid":"2619","level":"2","mid":"3058","name":"CENTER VISITS","children":[]}
        }

请帮帮我

【问题讨论】：

在 javascript 中，无法保证键出现在对象中的顺序，就像您在最终代码 sn-p 中指定的那样。（进一步阅读：stefanjudis.com/today-i-learned/…）。至少，您需要将 'children' 的值重构为一个数组。可以以不同方式访问 JSON 吗？也许遍历 l2_list 并为每个调用 element.children[list2_listElement] ？
你为什么需要它？如果您已经将 id 排序在一个数组中，为什么使用它来按所需顺序检索孩子还不够呢？遍历 l2_list 数组并将每个值用作子项的索引。
@gaetanoM，它不是重复的，我想按照 l2_list 中的给定顺序对数组进行排序

【解决方案1】：

假设在变量 a 中存储了您的对象

a = `{"l2_list": [2605,2608,2607,2626,2627,3057,3058],
    "children":
        {
            "2605":{"pid":"2619","level":"2","mid":"2605","name":"IDLING","children":[]},
            "2608":{"pid":"2619","level":"2","mid":"2608","name":"COMPLIANT DEPART","children":[]},
            "2607":{"pid":"2619","level":"2","mid":"2607","name":"COMPLIANT","children":[]},
            "2626":{"pid":"2619","level":"2","mid":"2626","name":"DISPATCHED","children":[]},
            "2627":{"pid":"2619","level":"2","mid":"2627","name":"HOURS","children":[]},
            "3057":{"pid":"2619","level":"2","mid":"3057","name":"OFFICE VISITS","children":[]},
            "3058":{"pid":"2619","level":"2","mid":"3058","name":"CENTER VISITS","children":[]}
        }}`

您可以填充按下一个代码排序的数组

sorted = [];
a.l2_list.forEach(number => {
   let str = number.toString();
    let obj = {};
     obj[str] = a.children[str];
   sorted.push(obj)
});
