vue 数组转对象与对象转数组（对象与数组的相互转换）

数组转对象

转换前为数组：

转换为对象的效果图：

return{     editScreenVenue:[              {label:'姓名', prop: 'name', size:'12',color: "#000",sort:0},              {label:'单位（公司）', prop: 'company',size:'12',color: "#000",sort:1},              {label:'手机号', prop: 'phone',size:'12',color: "#000",sort:2},              {label:'职务', prop: 'job',size:'12',color: "#000",sort:3},            ],//数组数据}

 methods: {// 数组转对象方法      arrayToObject (arr) {    let map = {};    arr.forEach (item => {      map[item.prop] = {label: item.label, color: item.color, size: item.size};    });    return map;  },//需要使用数组转对象的方法  getData(){  let newObj= this.arrayToObject(this.editScreenVenue);       console.log(newObj,'newObj');}  }

数组对象的相互转换

  mounted() {     let str = '{"name":{"label":"姓名","color":"#e2534d","size":"12"},"company":{"label":"单位（公司）","color":"#8165a0","size":"12"},"phone":{"label":"手机号","color":"#f9974c","size":"12"},"job":{"label":"职务","color":"#ddd8c3","size":"12"}}';let json = JSON.parse(str);let editScreenVenue = Object.entries(json).map(([prop, {label, color, size}]) => ({  label,  prop,  size,  color,}));console.log(editScreenVenue,'json转数组');  },

  mounted() {    let editScreenVenue = [  {label:'姓名', prop: 'name', size:'12',color: "#000",sort:0},  {label:'单位（公司）', prop: 'company',size:'12',color: "#000",sort:1},  {label:'手机号', prop: 'phone',size:'12',color: "#000",sort:2},  {label:'职务', prop: 'job',size:'12',color: "#000",sort:3},];let result = editScreenVenue.reduce((accumulator, current) => {  accumulator[current.prop] = {    size: current.size,    color: current.color,    lable: current.label,  };  return accumulator;}, {});console.log(result,'数组转对象');  },
