例:
1 arrold = [ 2 3 {name: "name1", age: "1"}, 4 {name: "name2", age: "2"}, 5 {name: "name3", age: "3"}, 6 {name: "name4", age: "4"}, 7 {name: "name5", age: "5"}, 8 {name: "name6", age: "6"} 9 ] 10 11 arrnew = ["name1","name2","name3","name4","name5","name6"]
方法一:
let arr = []; arrold.forEach(e => { arrnew.push(e.name) })
方法二:
let arrnew = arrold.map((obj,index) => { return obj.name; }).join(",").split(',')
方法二改进:
let arrnew = arrold.map((item,index) => { return Object.assign({},{'name':item.name}) })
关于Object.assign(target,sources)方法:拷贝源对象且可枚举的属性到目标对象,如果目标对象中的属性具有相同的键,则属性将被源中的属性覆盖。例:
const object1 = { a: 1, b: 2, c: 3 }; // object2: a=1, b=2, c=3, d=5 const object2 = Object.assign({c: 4, d: 5}, object1);
