对数组中的某对象排序

利用sort方法排序

例子: 对一组数组中的年龄排序.

var arr = [
    {name:'zopp',age:0},
    {name:'gpp',age:18},
    {name:'yjj',age:8}
];
// 降序
function compare(name){
    return function(a,b){
        return a[name] - b[name];
    }
}
// 打乱数组顺序
function disrupt(name){
    return function(a,b){
        return Math.random() > 0.5 ? -1 : 1;
    }
}
console.log(arr.sort(compare('age')))

结果,:

[
    {name:'zopp',age:0},
    {name:'yjj',age:8}
    {name:'gpp',age:18},
];
