In this article, I will explain you about AngularJS directive for email. At the point when executing a Single Page Application utilizing WebAPI and AngularJS, you experience numerous uses of filters and directives to meet requirements specified by clients. The accompanying code tokenizes the info and presentations it in a different square inside a particular placeholder, in any case it checks the data for a substantial email address first and then the information token is not rehashed inside the same placeholder. And now, write the following code:

<body ng-app="tokenizer"> 
    <div ng-controller="tokenizerController"> 
        <tag-input taglist='email' placeholder="Emails"></tag-input>   
    </div> 
</body> 


    var sample = angular.module('tokenizer', ['ngRoute']);              
    sample.controller('tokenizerController', function ($scope) {               
      }); 
             sample.directive('tagInput', function ()
    { 
           return
            { 
               restrict: 'E',                 
               scope:
                { 
                  inputTags: '=taglist', 
                   autocomplete: '=autocomplete' 
                  }, 
                   link: function ($scope, element, attrs)
                  { 
                   $scope.defaultWidth = 200; 
                   $scope.tagText = ''; 
                   $scope.placeholder = attrs.placeholder; 
                   $scope.tagArray = function ()
                      { 
                       if ($scope.inputTags === #ff0000)
                       { 
                           return []; 
                       } 
                       return $scope.inputTags.split(',').filter(function (tag)
                       { 
                           return tag !== ""; 
                       }); 
                   }; 
                   $scope.addTag = function ()
                       { 
                       var EMAIL_REGEXP = /^[_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/; 
                       var tagArray; 
                       if ($scope.tagText.length === 0) { 
                           return; 
                        } 
                       if (!EMAIL_REGEXP.test($scope.tagText))
                       { 
                           return $scope.tagText = ""; 
                       } 
                       tagArray = $scope.tagArray(); 
                       if (!(tagArray.indexOf($scope.tagText) >= 0))
                       { 
                           tagArray.push($scope.tagText); 
                           $scope.inputTags = tagArray.join(','); 
                       } 
                       return $scope.tagText = ""; 
                   }; 
                   $scope.deleteTag = function (key)
                       { 
                       var tagArray; 
                       tagArray = $scope.tagArray(); 
                       if (tagArray.length > 0 && $scope.tagText.length === 0 && key === #ff0000)
                      { 
                           tagArray.pop(); 
                       }
                       else
                         { 
                           if (key !== undefined)

                           $scope.inputWidth = tempEl.width() + 5; 
                           if ($scope.inputWidth < $scope.defaultWidth)
                           { 
                               $scope.inputWidth = $scope.defaultWidth; 
                           } 
                           return tempEl.remove(); 
                       } 
                   }); 
                   element.bind("keydown", function (e) { 
                       var key; 
                       key = e.which; 
                       if (key === 9 || key === 13) {
