  //        note: The examples are correct, this is a new way
  //        note: This function deviates from PHP in returning a copy of the array instead
  //        note: of acting by reference and returning true; this was necessary because
  //        note: IE does not allow deleting and re-adding of properties without caching
  //        note: of property position; you can set the ini of "phpjs.strictForIn" to true to
  //        note: get the PHP behavior, but use this only if you are in an environment
  //        note: such as Firefox extensions where for-in iteration order is fixed and true
  //        note: property deletion is supported. Note that we intend to implement the PHP
  //        note: behavior by default if IE ever does allow it; only gives shallow copy since
  //        note: is by reference in PHP anyways
  //        note: Since JS objects" keys are always strings, and (the
  //        note: default) SORT_REGULAR flag distinguishes by key type,
  //        note: if the content is a numeric string, we treat the
  //        note: "original type" as numeric.
  //  depends on: i18n_loc_get_default
  //  depends on: strnatcmp
  //   example 1: data = {d: "lemon", a: "orange", b: "banana", c: "apple"};
  //   example 1: data = ksort(data);
  //   example 1: $result = data
  //   returns 1: {a: "orange", b: "banana", c: "apple", d: "lemon"}
  //   example 2: ini_set("phpjs.strictForIn", true);
  //   example 2: data = {2: "van", 3: "Zonneveld", 1: "Kevin"};
  //   example 2: ksort(data);
  //   example 2: $result = data
  //   returns 2: {1: "Kevin", 2: "van", 3: "Zonneveld"}

  var tmp_arr = {},
    keys = [],
    sorter, i, k, that = vm,
    strictForIn = false,
    populateArr = {};

  switch (sort_flags) {
    case "SORT_STRING":
      // compare items as strings
      sorter = function (a, b) {
        return that.strnatcmp(a, b);
      };
      break;

上面寫好字典排序方法ksort，然后進行調用

let aa = ksort(
  this,
  {
    "app_id": "10000",
    "time_stamp":"1493449657",
    "nonce_str":"20e3408a79",
    "key1":"騰訊AI開放平臺",
    "key2":"示例僅供參考",
    "sign":""
  }
)

最后，字典排序后的順序為：
