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 $resource('phones/:phoneId.json', {}, {
query: {method: 'GET', params:{phoneId:'phones'}, isArray:true}
});
});
Answer
If you have not too much data, you can definitely do pagination by just storing all the data in the browser and filtering what's visible at a certain time.
Here's a simple pagination example from the list of fiddles on the angular.js [Github wiki](https://github.com/angular/angular.js/wiki/Resources%3A-JSFiddle- Examples), which should be helpful:
var app=angular.module('myApp', []);
function MyCtrl($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>
