自创在angularJS 1.5中使用示例？

Question

所有HTML和js一起用于自定义过滤器。在这里，当我们点击它过滤的主题名称

时，我将以点击过滤器为例

val ref = FirebaseDatabase.getInstance().reference
        val applesQuery = ref.child("L7jrJ6DtQWrmZsC4zvT")
        applesQuery.addListenerForSingleValueEvent(
                object : ValueEventListener {
                    override fun onDataChange(dataSnapshot: DataSnapshot) {
                        dataSnapshot.ref.removeValue()
                    }
                    override fun onCancelled(databaseError: DatabaseError) {
                        Log.e("frgrgr", "onCancelled", databaseError.toException())
                    }
                })

HTML代码

angular.module('testApp', []).controller('namesCtrl', function($scope) {
    $scope.names = [{
            name: 'Hindi'
        },
        {
            name: 'Math'
        },
        {
            name: 'English'
        },
        {
            name: 'Science'
        },
        {
            name: 'Computer'
        },
        {
            name: 'History'
        },

    ];
    $scope.orderByMe = function(x) {
        $scope.myOrderBy = x;
    }
});
