《前端面试题》- 编程题 - 对一个数组（多个对象）进行两级排序

问题

对一个数组（多个对象）进行两级排序，例如[{name: 'zhong', age: 18}, {name: 'xiaoli', age: 15}, {name: 'hong', age: 50}],先对name进行排序，再对age进行排序。

答案

function sortArrObject(arr) {
    return arr.sort(function(x, y) {
        if (x.name > y.name) {
            return 1;
        } else if (x.age > y.age) {
            return 1;
        }
    });
}

var arr = [{name: 'zhong', age: 18}, {name: 'zhong', age: 15}, {name: 'xiaoli', age: 15}, {name: 'hong', age: 50}];
console.log(sortArrObject(arr));

//[ { name: 'hong', age: 50 },
//{ name: 'xiaoli', age: 15 },
//  { name: 'zhong', age: 15 },
 // { name: 'zhong', age: 18 } ]
