比较两个数组对象并使用underscore.js- urgent删除重复项 [英] compare two array object and remove duplicate using underscore.js- urgent

问题描述

var a = [{Id：1，姓名：'a'}，{Id：2，姓名：'b'}，{Id：3，姓名： 'c'}，{Id：4，姓名：'d'}，{Id：5，姓名：'j'}];

var b = [{Id：1，姓名：'a'}，{Id：4，姓名：'d'}，{Id：5，姓名：'j'}，{ Id：9，姓名：'i'}];



我需要通过比较a和b删除a中的重复项使用下划线js







i需要像[0]一样检查所有b数组然后如果a [0]在b中然后是[0]删除，我不想要b的值



B仅用于检查重复的

var a = [{"Id": 1, "Name": 'a'}, {"Id": 2, "Name": 'b'}, {"Id": 3, "Name": 'c'},{"Id": 4, "Name": 'd'},,{"Id": 5, "Name": 'j'}];
var b = [{"Id": 1, "Name": 'a'}, {"Id": 4, "Name": 'd'}, {"Id": 5, "Name": 'j'},{"Id": 9, "Name": 'i'}];

I need to remove duplicate in "a" by comparing "a" with "b" using underscore js



i need to check like a[0] to all b array then if a[0] is in b then a[0] to remove, and i dont want value from b

B is only for checking duplicate
