根据数组中对象的属性值排序倒叙

数组中对象的属性值排序倒叙demo

function compare(e) {
  return function (a, b) {
    var value1 = a[e];
    var value2 = b[e];
    return parseInt(value1) - parseInt(value2);
  }
}
var arr=[{a:2},{a:3},{a:1}];

var arr2 = arr.sort(compare('time')).reverse();

console.log(arr2)  //[{a:3},{a:2},{a:1}]
