Hi rani,
You can use JavaScript Array sort and reverse method.
Check this example.
HTML
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<script type="text/javascript">
var app = angular.module('MyApp', [])
app.controller('MyController', function ($scope) {
$scope.Fruits = ['Mango', 'Apple', 'Banana', 'Orange', 'Guava'];
$scope.SortFruits = function (order) {
if (order == 'asc') {
$scope.Fruits.sort();
} else if (order == 'desc') {
$scope.Fruits.sort();
$scope.Fruits.reverse();
}
}
});
</script>
</head>
<body>
<div ng-app="MyApp" ng-controller="MyController">
<input type="button" value="Ascending Fruits" ng-click="SortFruits('asc')" />
<input type="button" value="Descending Fruits" ng-click="SortFruits('desc')" /><br />
<ol><li ng-repeat="fruit in Fruits">{{fruit}}</li></ol>
</div>
</body>
