Describe about Sort an Array Based on User Input.

Sort an Array Based on User Input

Click the table headers to change the sort order::

Name	Country
Jani	Norway
Carl	Sweden
Margareth	England
Hege	Norway
Joe	Denmark
Gustav	Sweden
Birgit	Denmark
Mary	England
Kai	Norway

By adding the ng-click directive on the table headers, we can run a function that changes the sorting order of the array:

Example

<div ng-app="myApp" ng-controller="namesCtrl">

<table border="1" width="100%">
  <tr>
    <th ng-click="orderByMe('name')">Name</th>
    <th ng-click="orderByMe('country')">Country</th>
  </tr>
  <tr ng-repeat="x in names | orderBy:myOrderBy">
    <td>{{x.name}}</td>
    <td>{{x.country}}</td>
  </tr>
</table>

</div>

<script>
angular.module('myApp', []).controller('namesCtrl', function($scope) {
  $scope.names = [
    {name:'Jani',country:'Norway'},
    {name:'Carl',country:'Sweden'},
    {name:'Margareth',country:'England'},
    {name:'Hege',country:'Norway'},
    {name:'Joe',country:'Denmark'},
    {name:'Gustav',country:'Sweden'},
    {name:'Birgit',country:'Denmark'},
    {name:'Mary',country:'England'},
    {name:'Kai',country:'Norway'}
  ];
  $scope.orderByMe = function(x) {
    $scope.myOrderBy = x;
  }
});</script>
