标签： javascript json

是否可以修改以下内容，以便在foreach上反转，以便最新的数据日期首先而不是最旧的最新日期？

不是普通forEach。可能性：

  • 假设它按升序排列。循环索引从length - 1到0。无损。
  • 假设它按升序排列。应用reverse，然后forEach。破坏性的。
  • 假设它未分类。对数组进行排序，然后应用forEach。破坏性的。
  • 假设它未分类。创建一个索引数组，按照数组中相应的值对索引进行排序，对索引应用forEach并访问数组成员。无损。
  • 假设它未分类。使用slice克隆数组，然后应用sort和forEach。无损。

你可以改变

json.TrackingRecord.MovementInformation.Movement.forEach(function(item) {

到

json.TrackingRecord.MovementInformation.Movement.reverse().forEach(function(item) {
                                                 ^^^^^^^^^

请记住，reverse实际上修改了数组，它不仅返回一个反转元素的数组。但是，这可能是你想要的，因为它应该按照这个顺序打印。

答案 2 :(得分：1)

在数组上向后迭代的非破坏性方法（除了for for循环）是 reduceRight ：

json.TrackingRecord.MovementInformation.Movement.reduceRight(function(acc, item) {
  // do stuff
}, null);
