Question

I’m trying to add pages to my list. I followed the AngularJS tutorial, the one about smartphones and I’m trying to display only certain number of objects. Here is my html file:

  <div class='container-fluid'>
    <div class='row-fluid'>
        <div class='span2'>
            Search: <input ng-model='searchBar'>
            Sort by: 
            <select ng-model='orderProp'>
                <option value='name'>Alphabetical</option>
                <option value='age'>Newest</option>
            </select>
            You selected the phones to be ordered by: {{orderProp}}
        </div>

        <div class='span10'>
          <select ng-model='limit'>
            <option value='5'>Show 5 per page</option>
            <option value='10'>Show 10 per page</option>
            <option value='15'>Show 15 per page</option>
            <option value='20'>Show 20 per page</option>
          </select>
          <ul class='phones'>
            <li class='thumbnail' ng-repeat='phone in phones | filter:searchBar | orderBy:orderProp | limitTo:limit'>
                <a href='#/phones/{{phone.id}}' class='thumb'><img ng-src='{{phone.imageUrl}}'></a>
                <a href='#/phones/{{phone.id}}'>{{phone.name}}</a>
                <p>{{phone.snippet}}</p>
            </li>
          </ul>
        </div>
    </div>
  </div>

I’ve added a select tag with some values in order to limit the number of items that will be displayed. What I want now is to add the pagination to display the next 5, 10, etc.

I have a controller that works with this:

function PhoneListCtrl($scope, Phone){
    $scope.phones = Phone.query();
    $scope.orderProp = 'age';
    $scope.limit = 5;
}

And also I have a module in order to retrieve the data from the json files.

angular.module('phonecatServices', ['ngResource']).
    factory('Phone', function($resource){
        return $resource('phones/:phoneId.json', {}, {
            query: {method: 'GET', params:{phoneId:'phones'}, isArray:true}
        });
    });

If you have not too much data, you can definitely do pagination by just storing all the data in the browser and filtering what’s visible at a certain time.

Here’s a simple pagination example from the list of fiddles on the angular.js Github wiki, which should be helpful:

var app=angular.module('myApp', []);

function MyCtrl($scope) {
    $scope.currentPage = 0;
    $scope.pageSize = 10;
    $scope.data = [];
    $scope.numberOfPages=function(){
        return Math.ceil($scope.data.length/$scope.pageSize);                
    }
    for (var i=0; i<45; i++) {
        $scope.data.push("Item "+i);
    }
}

//We already have a limitTo filter built-in to angular,
//let's make a startFrom filter
app.filter('startFrom', function() {
    return function(input, start) {
        start = +start; //parse to int
        return input.slice(start);
    }
});

<div ng-controller="MyCtrl">
    <ul>
        <li ng-repeat="item in data | startFrom:currentPage*pageSize | limitTo:pageSize">
            {{item}}
        </li>
    </ul>
    <button ng-disabled="currentPage == 0" ng-click="currentPage=currentPage-1">
        Previous
    </button>
    {{currentPage+1}}/{{numberOfPages()}}
    <button ng-disabled="currentPage >= data.length/pageSize - 1" ng-click="currentPage=currentPage+1">
        Next
    </button>
</div>
