Question

      <ion-content padding>
        <ion-list>
          <ion-item>
            <ion-label fixed>Username</ion-label>
            <ion-input type="text" value="" (ngModel)]="userData.username"></ion-input> </ion-item>
          <ion-item>
            <ion-label fixed>Password</ion-label>
            <ion-input type="password" (ngModel)]="userData.password"></ion-input>
          </ion-item>
          <button ion-button block color="primary" (click)="login()">Login</button>
        </ion-list>
      </ion-content>

当我访问y点击它正在抛出的按钮时，这是login.html代码找不到未定义的属性名称

login()
{
this.authServiceProvider.postData(this.userData,'login').then((result) => {
     this.responseData = result;
     console.log(this.responseData);
     localStorage.setItem('userData', JSON.stringify(this.responseData));
     this.navCtrl.push(TabsPage);
}, 
(err) => 
{
         // Error log
});
}

Answer 1

您在所有ngModel

中缺少 [

<ion-input type="text" value="" [(ngModel)]="userData.username"></ion-input> </ion-item>

找不到undefined的属性名称
