Angular Pagination

An AngularJS module for pagination on static or dynamic data. No directives here, just a service and some optional filters.

Mostly based on various snippets which @svileng found on JSFiddle, afterwards modified to support a wider variety of data sets. Also several useful helpers to cut down on controller and view math.

Quick start

Include angular-pagination.js after angular.min.js.

Add the pagination module as a dependency when creating your app, e.g.

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

Inject the Pagination service to the controller containing the data which you want to paginate, and set it on the $scope:

app.controller('MyCtrl', ['$scope', 'Pagination',
function($scope, Pagination){
  $scope.pg = new Pagination({start: 0, limit: 10, total: 10})
}])

If no object is passed to the constructor it assumes the following defaults

• start 0
• limit 10
• total 0

To set updated values on the same instance use the set method. This is especially useful on dynamic backend data sets that require callbacks. For static front-end data sets the filters can be used.

$scope.pg.set({start: 0, limit: 10, total: 10})

After setting the data either through calling new(obj) or set(obj) the service will automatically setup several helpers that can be used for rendering which are described below.

Rendering with Helpers

For dynamic server backed data sets it is good to use helpers over filters here is how.

• First Page my_start_var = pg.first(); myListFunction()
• Previous Page my_start_var = pg.previous(); myListFunction()
• Next Page my_start_var = pg.next(); myListFunction()
• Last Page my_start_var = pg.last(); myListFunction()
• Specific page my_start_var = pg.forPage(3); myListFunction()

This example assume you have a controller like this

app.controller('MyCtrl', ['$scope', 'Pagination',
function($scope, Pagination){
  $scope.my_start_var = 0
  $scope.pg = new Pagination({start: 0, limit: 10, total: 10})
  $scope.myListFunction = function(){
    someFactory.list({start: my_start_var},function(res){
      $scope.pg.set({start: my_start_var, total: res.count_total})
    })
  }
}])

Here is an example view using jade with bootstrap buttons it uses the buttons() method which returns an array of buttons relative to the current page position

div
    div.pull-right
      div.btn-group
        button.btn.btn-default(ng-disabled="pg.isFirst()", ng-click="start = pg.first(); list()")
          span.glyphicon.glyphicon-fast-backward
        button.btn.btn-default(ng-disabled="pg.isFirst()", ng-click="start = pg.previous(); list()")
          span.glyphicon.glyphicon-step-backward
        button.btn.btn-default(
          ng-repeat="n in pg.buttons()",
          ng-class="{'btn-primary': (n == pg.page)}",
          ng-click="$parent.start = pg.forPage(n); list()"
        ) {{ n }}
        button.btn.btn-default(ng-disabled="pg.isLast()", ng-click="start = pg.next(); list()")
          span.glyphicon.glyphicon-step-forward
        button.btn.btn-default(ng-disabled="pg.isLast()", ng-click="start = pg.last(); list()")
          span.glyphicon.glyphicon-fast-forward
    | {{ pg.range.start }} - {{ pg.range.end }} of {{ pg.range.total }} entries

Which should yield something like this:

Dynamic Limit

Sometimes it is useful to change the limit per page dynamically say with a drop down. That is where forLimitChange() becomes useful as it will return the correct start value after a limit change which will allow everything to line up correctly and the user to be on a correct page. This will also make sure the database is set to return the correct starting record as well.

Here is an example:

div
  select(ng-model="limit", ng-change="start = pg.forLimitChange(limit); list()")
    option(ng-repeat="row in [10,20,50,100,500]", ng-value="row") {{ row }}
  |  Per page

In the above example we pass in the currently set limit to get the "would be" start value. If the database has already been changed then the currently lined up value can be obtained by doing

$scope.start = pg.forLimitChange()

Rendering with Filters

There is a custom filter called paginationStart to help you rendering items per page.

<div ng-repeat="post in posts | paginationStart: pg.start | limitTo: pg.limit">
	<!-- stuff -->
</div>

Again, replace post in posts with your data.

For pagination links you can either use Next/Previous buttons or page numbers by using another built-in filter called paginationRange.

<button ng-click="pg.set({start: pg.previous()})">Previous</button>
<button ng-click="pg.set({start: pg.next()}).">Next</button>

and for rendering page numbers:

<span ng-repeat="n in [] | paginationRange: pg.pages">
	<button ng-click="pg.set({start: pg.forPage(n)})">{{n}}</button>
<span>

Optionally you can add some logic to hide/disable the buttons using the pg.isFirst() and pg.isLast() functions; here's an example:

<button ng-disabled="pg.isFirst()" ng-click="pg.set({start: pg.first()})">First</button>
<button ng-disabled="pg.isFirst()" ng-click="pg.set({start: pg.previous()})">Previous</button>
<button ng-disabled="pg.isLast()" ng-click="pg.set({start: pg.next()}).">Next</button>
<button ng-disabled="pg.isLast()" ng-click="pg.set({start: pg.last()}).">Last</button>
