js中对象的自定义排序

 1 //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
 2         var compareAsc = function (prop) {
 3             return function (obj1, obj2) {
 4                 var val1 = obj1[prop];
 5                 var val2 = obj2[prop];
 6                 if (!isNaN(Number(val1)) && !isNaN(Number(val2))) {
 7                     val1 = Number(val1);
 8                     val2 = Number(val2);
 9                 }
10                 if (val1 < val2) {
11                     return -1;
12                 } else if (val1 > val2) {
13                     return 1;
14                 } else {
15                     return 0;
16                 }            
17             } 
18         }
19         var compareDesc = function (prop) {
20             return function (obj1, obj2) {
21                 var val1 = obj1[prop];
22                 var val2 = obj2[prop];
23                 if (!isNaN(Number(val1)) && !isNaN(Number(val2))) {
24                     val1 = Number(val1);
25                     val2 = Number(val2);
26                 }
27                 if (val1 > val2) {
28                     return -1;
29                 } else if (val1 < val2) {
30                     return 1;
31                 } else {
32                     return 0;
33                 }            
34             } 
35         }

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：

 1 $scope.up=true;
 2         $scope.down = false;
 3         $scope.upDown = function(i) {
 4             $scope.up=!$scope.up;
 5             $scope.down=!$scope.down
 6             if($scope.up == true && $scope.down == false){
 7                 intData.sort(compareAsc("price"));
 8             }else if($scope.up == false && $scope.down == true){
 9                 intData.sort(compareDesc("price"));
10             }
11         };

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>
