請(qǐng)問(wèn)大家，如何將對(duì)象中的順序按照key數(shù)組中的值進(jìn)行排序（keys的順序是不變的 這里的問(wèn)題就是將obj按照300 200 100 400重新排一下，返回一個(gè)新的obj）如題：var obj = {    100: { name: '100' },    200: { name: '200' },    300: { name: '300' },    400: { name: '400' }};var keys = [ 300, 100, 200, 400];結(jié)果：var obj = {300: { name: '300' },100: { name: '100' },200: { name: '200' },400: { name: '400' }};
