合并两个匹配id的数组

本文介绍了合并两个匹配id的数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有两个数组，比如

var members = [{docId: "1234", userId: 222}, {docId: "1235", userId: 333}]; var memberInfo = [{id: 222, name: "test1"}, {id: 333, name: "test2"}];

我需要将它合并到以编程方式匹配用户ID的单个数组

I need to merge this to a single array programatically matching the user ids

最后一个数组应该像

var finalArray = [{docId: "1234", userId: 222, name: "test1"}, {docId: "1235", userId: 333, name: "test2"}]

有没有更简洁的方法来做到这一点，我在我的应用程序中有下划线库，但我找不到一个干净的方法来实现这个

Is there a cleaner way to do this, I have underscore library in my app, but I couldn't find a clean method to achieve this

推荐答案

使用下划线的解决方案：

A solution using underscore:

var finalArray = _.map(members, function(member){ return _.extend(member, _.omit(_.findWhere(memberInfo, {id: member.userId}), 'id')); });

_。map

使用 _。findWhere

_。延伸 会员信息

_.map across the members

find the matching member info using _.findWhere

_.omit the id key from the matching member info

_.extend the member with the member info
