Pagination on a list using ng-repeat

angularjs, javascript, pagination

Solution

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>

Problem

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} }); }); ```
