javascript - 单击按钮时我没有得到输出

Question

我知道如何用纯 javascript 编写此代码，但我对 Angular 很陌生..单击提交时我没有得到任何结果..

index.html

<input type="text"   ng-model="username" placeholder="Username">
      <input type="password"   ng-model="password" placeholder="Password">
      <ion-button expand="block" name="submit" (click)="login()">Login</ion-button>

索引.ts

    export class LoginPage implements OnInit {
      username;
      password;

      login() {
        if(this.username == "admin" && this.password == "admin") {
          alert("helow")
        }
      }

Answer 1

使用 [(ngModel)] 更改 ng-model

<input type="text" [(ngModel)]="username" placeholder="Username">
<input type="password" [(ngModel)]="password" placeholder="Password">
<ion-button expand="block" name="submit" (click)="login()">Login</ion-button>
