Js 数组对象排序

1.定义函数

 /**
     * 数组对象排序函数
     * @param {any} name 排序字段
     * @param {any} order 升、降(这里事true、false记得处理下)
     */
    var by = function (name,order) {
        return function (o, p) {
            var a, b;
            if (typeof o === "object" && typeof p === "object" && o && p) {
                a = o[name];
                b = p[name];
                if (a === b) {
                    return 0;
                }
                if (typeof a === typeof b) {
                    if (order) {
                        return a < b ? -1 : 1;
                    }
                    return a > b ? -1 : 1;
                }
                if (order) {
                    return typeof a < typeof b ? -1 : 1;
                }
                return typeof a > typeof b ? -1 : 1;

            }
            else {
                throw ("error");
            }
        }
    }

2.使用方式

//数组
var employees=[]
employees[0]={name:"George", age:32, retiredate:"March 12, 2014"}
employees[1]={name:"Edward", age:17, retiredate:"June 2, 2023"}
employees[2]={name:"Christine", age:58, retiredate:"December 20, 2036"}
employees[3]={name:"Sarah", age:62, retiredate:"April 30, 2020"}
//调用
employees.sort(by("age"),true);
