How to do paging in AngularJS?

Asked 2012-05-30T12:14:38.670

I have a dataset of about 1000 items in-memory and am attempting to create a pager for this dataset, but I'm not sure on how to do this.

I'm using a custom filter function to filter the results, and that works fine, but somehow I need to get the number of pages out.

Any clues?

Angular UI Bootstrap - Pagination Directive

Check out UI Bootstrap's pagination directive. I ended up using it rather than what is posted here as it has enough features for my current use and has a thorough test spec to accompany it.

View

<!-- table here -->

<pagination 
  ng-model="currentPage"
  total-items="todos.length"
  max-size="maxSize"  
  boundary-links="true">
</pagination>

<!-- items/page select here if you like -->

Controller

todos.controller("TodoController", function($scope) {
   $scope.filteredTodos = []
  ,$scope.currentPage = 1
  ,$scope.numPerPage = 10
  ,$scope.maxSize = 5;

  $scope.makeTodos = function() {
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
      $scope.todos.push({ text:"todo "+i, done:false});
    }
  };
  $scope.makeTodos(); 

  $scope.$watch("currentPage + numPerPage", function() {
    var begin = (($scope.currentPage - 1) * $scope.numPerPage)
    , end = begin + $scope.numPerPage;

    $scope.filteredTodos = $scope.todos.slice(begin, end);
  });
});

I have made a working plunker for reference.


Legacy Version:

View

<!-- table here -->

<div data-pagination="" data-num-pages="numPages()" 
  data-current-page="currentPage" data-max-size="maxSize"  
  data-boundary-links="true"></div>

<!-- items/page select here if you like -->

Controller

todos.controller("TodoController", function($scope) {
   $scope.filteredTodos = []
  ,$scope.currentPage

I've extracted the relevant bits here. This is a 'no frills' tabular pager, so sorting or filtering is not included. Feel free to change/add as needed:

     //your data source may be different. the following line is 
     //just for demonstration purposes only
    var modelData = [{
      text: 'Test1'
    }, {
      text: 'Test2'
    }, {
      text: 'Test3'
    }];

    (function(util) {

      util.PAGE_SIZE = 10;

      util.range = function(start, end) {
        var rng = [];

        if (!end) {
          end = start;
          start = 0;
        }

        for (var i = start; i < end; i++)
          rng.push(i);

        return rng;
      };

      util.Pager = function(data) {
        var self = this,
          _size = util.PAGE_SIZE;;

        self.current = 0;

        self.content = function(index) {
          var start = index * self.size,
            end = (index * self.size + self.size) > data.length ? data.length : (index * self.size + self.size);

          return data.slice(start, end);
        };

        self.next = function() {
          if (!self.canPage('Next')) return;
          self.current++;
        };

        self.prev = function() {
          if (!self.canPage('Prev')) return;
          self.current--;
        };

        self.canPage = function(dir) {
          if (dir === 'Next') return self.current < self.count - 1;
          if (dir === 'Prev') return self.current > 0;
          return false;
        };

        self.list = function() {
          var start, end;
          start = self.current < 5 ? 0 : self.current - 5;
          end = self.count - self.current < 5 ? self.count : self.current + 5;
          return Util.range(start, end);
        };

        Object.defineProperty(self, 'size', {
