前言

js 数组对象的合并，方便自己后续使用与学习,废话少说，这段代码的功能就是根据某个相同的value值合并两个数组对象

比如:根据相同的hotelId来合并

一 ， 数组对象根据相同属性值合并两个对象

话不多说，直接上代码

const hotelList = [{hotelId:'70931',price:'350',hotelName:'如家',address:'西乡地铁站A口',},{hotelId:'70932',price:'350',hotelName:'如家',address:'西乡地铁站A口', },{hotelId:'70933',price:'350',hotelName:'如家',address:'西乡地铁站A口',},{hotelId:'70934',price:'350',hotelName:'如家',address:'西乡地铁站A口',}];const hotelList1 = [{hotelId:'70931',price:'458',hotelName:'如家'},{hotelId:'70932',price:'360',hotelName:'速8酒店' },{hotelId:'70933',price:'850',hotelName:'7天'},{hotelId:'70934',price:'4250',hotelName:'格林豪泰'},{hotelId:'70935',price:'100',hotelName:'如意宾馆'},{hotelId:'70936',price:'1350',hotelName:'中天美景大酒店'}];// 把数组hotelList1合并hotelListconst newArr = hotelList.map(hotelItem => {const data = hotelList1.find(i => hotelItem.hotelId === i.hotelId)return {...hotelItem,...data,}})// 合并后的结果如下,正好是我想要的结果console.log(newArr);// (4) [{…}, {…}, {…}, {…}]// 0: {hotelId: '70931', price: '458', hotelName: '如家', address: '西乡地铁站A口'}// 1: {hotelId: '70932', price: '360', hotelName: '速8酒店', address: '西乡地铁站A口'}// 2: {hotelId: '70933', price: '850', hotelName: '7天', address: '西乡地铁站A口'}// 3: {hotelId: '70934', price: '4250', hotelName: '格林豪泰', address: '西乡地铁站A口'}// length: 4// [[Prototype]]: Array(0)

二 ，判断两个对象数组内的值是否相等

// 判断两个对象数组内的值是否完全相等let arr1 = [{"id": 1, "name": "张三" },{"id": 33, "name": "测试name"}];let arr2 = [{"id": 1, "name": "张三" }];var data = JSON.stringify(arr1) === JSON.stringify(arr2);console.log(data); //false
