script.js

angular.module('app',['ui.bootstrap']).controller('registrationCtrl', ['$scope','$modal',function ($scope, $modal)
    {

        $scope.openRegistration = function ()
        {
            //console.log("inside openLogin");
            var modalInstance =$modal.open(
                {
                    templateUrl: 'registration.html',
                    controller: 'registrationPopupController',
                    backdrop: 'static',
                    keyboard: false,
                    size: 'sm'
                });
            //console.log("done open")
        }
    }]).controller('registrationPopupController', ['$location','$scope','$modalInstance',function ($location,$scope,$modalInstance,LoginService)
    {

        $scope.user={
            pwd1:''
        };
        $scope.$watch('user.pwd1',function(newV,oldV){
          if(newV!=oldV){
          alert(newV)
            console.log(newV,oldV);
          }

        },true);


        $scope.cancel = function ()
        {
            $modalInstance.dismiss('cancel');
            location.href='#/';
        };

    }]);

我面临的问题是在密码文本框中写入时，我的 $watch 不会在模态实例控制器中调用。但是当我用同一个简单的控制器编写时它会工作，请帮助我！！

您的 ng-model 值有错字，应该是 user.pwd1 而不是 user.pw1

标记

<input type="password" id="pwd1" name="pw1" ng-model="user.pw1" ng-required="" />

即使使用 like $scope.user={pwd1:''}，$watch 也无法在 Modal 中工作

$watch is not working in Modal even though using like $scope.user={pwd1:''}
