利用数组api ——> sort来进行排序
var person = [
{name:"Rom",age:12},
{name:"Bob",age:22},
{name:"Ma",age:5},
{name:"Tony",age:25}
]
person.sort((a,b)=>{ return a.age-b.age})//升序
person.sort((a,b)=>{ return b.age-a.age})//降序
var person = [
{name:"Rom",age:12},
{name:"Bob",age:22},
{name:"Ma",age:5},
{name:"Tony",age:25}
]
person.sort((a,b)=>{ return a.age-b.age})//升序
person.sort((a,b)=>{ return b.age-a.age})//降序
