Question

我创建了一个发送电子邮件的模式。我正在检查输入以进行验证。但是我得到了未定义的函数错误。错误代码是：

ReferenceError：未定义validateEmail

我添加了angularjs脚本。 Ng-app已启动。另外，如何使用ng-if语句显示错误。

模态代码

Answer 1

在$ scope对象中定义的validateEmail和validateGsm函数然后必须与＆＃34; $ scope一起使用。＆＃34;前缀也可以使用下面正确的代码。

var name=$scope.name;
var email=$scope.validateEmail($scope.email);
var message=$scope.message;
var phone=$scope.validateGsm($scope.phone);
