我只需要在成员数组中发送带有（，）的memberId值，该怎么做？像

members [( 0: "99489ea4-6d34-11e8-80cd-001dd8b71cd8", 1: "99489ea4-6d34-11e8-80cd-001dd8b71cd8", 2: "99489ea4-6d34-11e8-80cd-001dd8b71cd8")]

Answer 1

您可以使用Array.map

var memberIds = members.map( m => m.memberId)

这将从您给定的数据结构中选择成员ID，并将其存储在新数组中

然后您可以更改原始结构

{
  ... // other props
  members: memberIds
}

由于不建议进行突变，所以我建议创建一个原始数据的克隆，然后将其突变

如何仅发送一个数组值（不包含两个值）？
