AngularJS ng-maxlength Directives

The AngularJS ng-maxlength directive is used to add the maxlength validator to ngModel. It can be used with text-based input controls, but can also be applied to custom text-based controls.

Syntax

<input type="text" ng-model="model" id="input" name="input" ng-maxlength="maxlength" />

Example

<!DOCTYPE html>    
<html>    
<head> <!-- www.techstrikers.com -->    
<title>ngMaxLength Test Sample</title>    
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.5.0/angular.min.js"></script>    
    
<script>    
  var app = angular.module('MaxlengthExample', [])
    app.controller('MaxlengthController', ['$scope', function($scope) {
      $scope.maxlength = 5;
    }]);  
</script>    
</head>
