AngularJS Custom filters Create a filter with parameters
Example
By default, a filter has a single parameter: the variable it is applied on. But you can pass more parameter to the function:
angular
.module('app', [])
.controller('MyController', function($scope) {
$scope.example = 0.098152;
})
.filter('percentage', function($filter) {
return function (input, decimals) {
return $filter('number')(input * 100, decimals) + ' %';
};
});
Now, you can give a precision to the percentage filter:
<span ng-controller="MyController">{{ example | percentage: 2 }}</span>
=> "9.81 %"
... but other parameters are optional, you can still use the default filter:
<span ng-controller="MyController">{{ example | percentage }}</span>
=> "9.8152 %"
