Js比较对Object类型进行排序

 <script>
     var data=[{name:"121",age:"18",year:"2018"},{name:"132",age:"16",year:"2019"}]
     /**
      * 创建比较参数函数
      * @param propertyName 属性名
      * @returns {Function} 返回比较函数
      */
     function compareFunction(propertyName){
         return function (src,tar) {
             //获取比较的值
             var v1=src[propertyName];
             var v2=tar[propertyName];
             if(v1>v2){
                 return 1;
             }
             if(v1<v2){
                 return -1;
             }
             return 0;
         };
     }
     //按照age进行比较
     data.sort(compareFunction("age"));
     alert(data[0].name);
     //按照year进行比较
     data.sort(compareFunction("year"));
     alert(data[0].name)
