Question

"TypeError: Cannot read property 'username' of undefined

at Scope.$scope.login (http://127.0.0.1:8020/www/main/user/login_controller.js:12:22)

Answer 1

控制器里先声明下 $scope.data={
username:'',password:''
}
写在 $scope.login 外边 data 不要以参数形式传进来

                $scope.data = {
                    username: ''
                }
                
                $scope.login = function() {
                    console.log($scope.data)
                }

<input type="text" name="" value="" ng-model='data.username'>{{data.username}}
<a ng-click="login()">按钮</a>
