问题是表单元素没有包含在定义ngApp指令的元素中。如果您重新排列元素，以便表单是具有ng-app属性的div的后代，您应该得到您想要的内容

  var myApp = angular.module('myApp', []);

  myApp.controller('Main', ['$scope',
    function($scope) {
      $scope.FormName = 'FormNameValidation';
      $scope.showFormValidation = function(statusValid, statusDirty) {
        $scope.FormNameValidationStatus = statusValid;
        $scope.FormNameDirtyStatus = statusDirty;
      }

    }
  ]);
