Angular js client side pagination like google.

Here we read about simple angular js client side pagination, now it’s time to do advanced client side pagination. Here i am going to explain about Pagination like google using angular js client side logic. First load all data to UI.

View

Here datalist is the data you are getting from service (backend).


<ul>
<li class="paginationclass" ng-repeat="datalist in datalists 
| pagination : currentPage*itemsPerPage | limitTo: itemsPerPage">
 
 <div>
 <span> Name : {{ datalist.name }}</span>
 <span> Age : {{ datalist.age }}</span>
 <span> Designation : {{ datalist.Designation }}</span>
 </div> 
</li>
</ul> 

Pagination div



<div class="pagination-div">
 
 <ul class="pagination">
  
  <li ng-class="DisablePrevPage()">
  
  <a href ng-click="prevPage()"> Prev</a>
  
  </li>
  
  <li ng-repeat="n in range()" 
  
  ng-class="{active: n == currentPage}"
  
  ng-click="setPage(n)">
  
  <a href="#">{{n+1}}</a>
  
  </li>
  
  <li ng-class="DisableNextPage()">
  
  <a href ng-click="nextPage()">Next </a>
  
  </li>
 
 </ul>

</div>


Controller

Here datalist is the data you are getting from service (backend).


 
 $scope.itemsPerPage = 5;
 
 $scope.currentPage = 0;
 
 $scope.datalists = data ;// Service
 
 

 

$scope.range = function() {

 var rangeSize = 4;

 var ps = [];

 var start;

 start = $scope.currentPage;

 if ( start > $scope.pageCount()-rangeSize ) {

  start = $scope.pageCount()-rangeSize+1;

  }

 for (var i=start; i<start+rangeSize; i++) {

 ps.push(i);

}

return ps;

};


$scope.prevPage = function() {

if ($scope.currentPage > 0) {

$scope.currentPage--;

}
};


$scope.DisablePrevPage = function() {

return $scope.currentPage === 0 ? "disabled" : "";

};


$scope.pageCount = function() {

return Math.ceil($scope.datalists.length/$scope.itemsPerPage)-1;

};


$scope.nextPage = function() {

if ($scope.currentPage > $scope.pageCount()) {

$scope.currentPage++;

}
};


$scope.DisableNextPage = function() {

return $scope.currentPage === $scope.pageCount() ? "disabled" : "";

};


$scope.setPage = function(n) {

$scope.currentPage = n;

};

Add all of these in your controller

Filter

You can declare this in filter.js or controller itself or in directive.


angular.module('sampleapp').filter('pagination', function()
{
  return function(input, start) {
    start = parseInt(start, 10);
    return input.slice(start);
  };
});


Working Demo

As TomALex mentioned in the comment "i noticed is if you set "itemsPerPage" to 300, we will see -2,-1,0 in pagination."

For that fix , please refer this updated fiddle

Updated Fiddle

The fix was - Add a check before pushing 'i' in $scope.range function



for (var i=start; i<start+rangeSize; i++) {
     if(i>=0) 
        ps.push(i);
    }

  5. Hi!
    Youy jsfiddle sample is helpful and thanks for sharing! But I want to change your sample - if a user clicked page #2, 3 or 4, I want to keep pagination "1, 2, 3, 4" NOT 2, 3, 4, 5 or 3, 4, 5, 6. Only refresh if the last one is clicked.
