js中对象的自定义排序

 //并返回一个可以用来对包含该成员的对象数组进行排序的比较函数
         var compareAsc = function (prop) {
             return function (obj1, obj2) {
                 var val1 = obj1[prop];
                 var val2 = obj2[prop];
                 if (!isNaN(Number(val1)) && !isNaN(Number(val2))) {
                     val1 = Number(val1);
                     val2 = Number(val2);
                 }
                 if (val1 < val2) {
                     return -1;
                 } else if (val1 > val2) {
                     return 1;
                 } else {
                     return 0;
                 }
             }
         }
         var compareDesc = function (prop) {
             return function (obj1, obj2) {
                 var val1 = obj1[prop];
                 var val2 = obj2[prop];
                 if (!isNaN(Number(val1)) && !isNaN(Number(val2))) {
                     val1 = Number(val1);
                     val2 = Number(val2);
                 }
                 if (val1 > val2) {
                     return -1;
                 } else if (val1 < val2) {
                     return 1;
                 } else {
                     return 0;
                 }
             }
         }

原始js中的排序不能满足：

arr.sort(sortNumber);
arr.sort(function (a, b) {
return b.name < a.name;
});

商城列表-积分由高到低由低到高排列：

 $scope.up=true;
         $scope.down = false;
         $scope.upDown = function(i) {
             $scope.up=!$scope.up;
             $scope.down=!$scope.down
             if($scope.up == true && $scope.down == false){
                 intData.sort(compareAsc("price"));
             }else if($scope.up == false && $scope.down == true){
                 intData.sort(compareDesc("price"));
             }
         };

html：

<a class="col col-50" ng-click="upDown()">{{'jifen.sortUp' | i18next}} &nbsp;&nbsp;<i ng-class="{'ion-ios-arrow-thin-up':up,'ion-ios-arrow-thin-down':down }" class="icon "></i></a>
