Question

我在使用cookies方面遇到了麻烦。当我在我的项目中使用ngCookies时，我的div（警报）出现了问题。 enter image description here

这是我的app.js

angular.module('postLogin', [ngCookies])
.controller('PostController', ['$scope', '$http', function($scope, $http) {        
        this.postForm = function() {
            var encodedString = 'username=' +
                encodeURIComponent(this.inputData.username) +
                '&password=' +
                encodeURIComponent(this.inputData.password);

            $http({
                method: 'POST',
                url: 'userauth.php',
                data: encodedString,
                headers: {'Content-Type': 'application/x-www-form-urlencoded'}
            })

            .success(function(data) {
                    //console.log(data);
                    if ( data.trim() === 'correct') {
                        window.location.href = 'success.html';
                    } else {
                        $scope.errorMsg = "Username and password do not match.";
                    }
            })            
        }
}]);

这是我的index.html

      </div>
      <script src="app.js"></script>
   </body>
</html>

当我没有使用ngCookies时

angular.module('postLogin', [])

它可以正常运行。请帮助我，我真的希望它将我的登录表单中的用户名扔到下一页。我不能在php中使用像会话这样的$ cookies。感谢。

在模块设置器（angular.module ...）中，当您注入依赖模块时，它们必须在引号中。在您的示例中，ngCookies周围没有引号。此外，您的index.html似乎没有引用angular-cookies.js文件，该文件不是基本angular.js文件的一部分。

检查开发工具是否存在特定错误（F12）。

如何在angularjs
