我正在尝试使用
Scala.JS和Angular实现一个应用程序,我在提交表单时遇到类型转换的问题.
我有以下代码:
<div ng-controller="usersCtrl"> <form novalidate class="simple-form"> First Name: <input type="text" ng-model="user.firstName" /><br /> Last Name: <input type="text" ng-model="user.lastName" /><br /> E-mail: <input type="email" ng-model="user.email" /><br /> Password: <input type="password" ng-model="user.password" /><br /> ConfirmPassword: <input type="password" ng-model="user.passwordConfirmation" /><br /> <input type="submit" ng-click="controller.signup(user)" value="Save" /> </form>
@JSExport @injectable("usersCtrl") class UsersCtrl( scope: UseRSScope,proxy: UseRSServiceProxy,val timeout: Timeout) extends AbstractController[UseRSScope](scope) { @JSExport def signup(user: UserSignup): Future[User] = { proxy.signup(scope.user) } } @JSExportAll case class UserSignup(firstName: String,lastName: String,email: String,password: String,passwordConfirmation: String)
但是当我尝试提交表单时,我收到以下错误:
$c_sjsr_UndefinedBehaviorError {s$1: "An undefined behavior was detected: [object Object] is not an instance of rentalot.users.UserSignup",e$1: $c_jl_ClassCastException
我已经尝试了几个选项,包括通过作用域获取用户,将用户变量定义为UserSignup或UndefOf [UserSignup],但没有运气.当我尝试执行scope.user.toOption时后者失败.
有什么想法吗?
解决方法
Scala.JS无法自动将JS对象转换为Scala案例类.您需要定义一个外观.参见
this document.
它应该看起来像这样:
它应该看起来像这样:
@js.native trait UserSignup extends js.Object { def firstName: String = js.native def lastName: String = js.native ... }
