Angular 验证错误

Question

我有两种形式的注册和登录，代码是在单个控制器下编写的，有两个函数调用提交第一个表单工作正常，但注册总是显示错误在 https://plnkr.co/edit/RS2LVc?p=preview

中预览

var app = angular.module('abc', []);
  app.controller('login', function ($scope) {
    scope.LoginValidator = function ($event) {
            if ($scope.LoginForm.$valid) {
                  console.log('Logged In');
            } else {
                        console.log("invalid");
                        if ($scope.LoginForm.Email.$invalid) {
                            $scope.mailRequire = true;
                        }
                        if ($scope.LoginForm.password.$invalid) {
                            $scope.passRequire = true;
                        }
                        $event.preventDefault();
                  }
            };

然后第二个函数从这里开始并显示错误

$scope.SignupValidator = function ($event) {

if ($scope.SignupForm.$valid) {
    console.log("Valid");
} else {
    alert('InValid Data');
    if ($scope.SignupForm.Fullname.$invalid) {
        $scope.namerequire = true;
    }
    if ($scope.SignupForm.email.$invalid) {
        $scope.emailrequire = true;
    }
    if ($scope.SignupForm.rollno.$invalid) {
        $scope.rollrequire = true;
    }
    if ($scope.SignupForm.password.$invalid) {
        $scope.passwordrequire = true;
    }
    if ($scope.SignupForm.confirm.$invalid) {
        $scope.confirmrequire = true;
    }
    $event.preventDefault();
}

};
});

我更新了 plunkr 文件，请检查:-

// Code goes here
var app = angular.module('abc', []);

app.controller('login', function ($scope) {
    $scope.LoginValidator = function ($event) {
        if ($scope.LoginForm.$valid) {
            console.log('Logged In');
        } else {
            console.log("invalid");
            if ($scope.LoginForm.Email.$invalid) {
                $scope.mailRequire = true;
            }
            if ($scope.LoginForm.password.$invalid) {
                $scope.passRequire = true;
            }
            $event.preventDefault();
        }
    };

    $scope.SignupValidator = function ($event) {

        if ($scope.SignupForm.$valid) {
            console.log("Valid");
        } else {
            alert('InValid Data');
            if ($scope.SignupForm.Fullname.$invalid) {
                $scope.namerequire = true;
            }
            if ($scope.SignupForm.email.$invalid) {
                $scope.emailrequire = true;
            }
            if ($scope.SignupForm.rollno.$invalid) {
                $scope.rollrequire = true;
            }
            if ($scope.SignupForm.password.$invalid) {
                $scope.passwordrequire = true;
            }
            if ($scope.SignupForm.confirm.$invalid) {
                $scope.confirmrequire = true;
            }
            $event.preventDefault();
        }
    };
});

Answer 2

单选按钮有误，要验证单选按钮，它需要一个值。所以将单选按钮 html 更改为下方

<input type="radio" name='Gender' ng-model="gender" value="male" ng-required="!gender"><i class="fa fa-circle-o fa-2x"></i><i class="fa fa-check-circle-o fa-2x"></i><span> Male</span>


<input type="radio" name='Gender' ng-model="gender" value="female" ng-required="!gender"><i class="fa fa-circle-o fa-2x"></i><i class="fa fa-check-circle-o fa-2x"></i><span> Female</span>
