用于分页的angular js控制器错误

Question

I am coding in angular js for client side pagination.

Starting in other question here about pagination, I've transformed the code to this but doesn't work.

What is wrong?

myapp.controller('MainCtrl', function($scope, Events) {
  $scope.mydata = [];

  Events.query(function(data) {
    $scope.mydata = data;
  });


  $scope.get = function (offset, limit) {
    return $scope.mydata.slice( offset, offset+limit );
  };

  $scope.count = function () {
    return $scope.mydata.length;
  };

  $scope.numPerPage = 5;
  $scope.noOfPages = Math.ceil($scope.count / $scope.numPerPage);
  $scope.currentPage = 1;

  $scope.setPage = function () {
    $scope.data = $scope.get( ($scope.currentPage - 1) * $scope.numPerPage,   $scope.numPerPage );
  };

  $scope.$watch( 'currentPage', $scope.setPage );
});

$scope.get and $scope.count don't work. Events.query is getting all JSON data from service in array format.

I can test this code in chrome angular js extension.

Any idea?

在HTML中使用{{mydata.length}}而不是$scope.count函数。
