一、获取数组对象中某一值封装为数组
const data = [ { date: '2016-05-02', name: '王小虎', address: '上海市普陀区金沙江路 1518 弄' }, { date: '2016-05-04', name: '王小虎', address: '上海市普陀区金沙江路 1517 弄' }, { date: '2016-05-01', name: '王小虎', address: '上海市普陀区金沙江路 1519 弄' }, { date: '2016-05-03', name: '王小虎', address: '上海市普陀区金沙江路 1516 弄' } ] var result = data.map(function (item) { return item.date; }); console.log(result) // ["2016-05-02", "2016-05-04", "2016-05-01", "2016-05-03"]二、处理数据对象中的某个字段
const result = data.map(item => { return {...item, content: JSON.parse(item.content) } })
