Question

我正在尝试绑定一个简单的选择或一个离子选择，但是现在，它只是不起作用...

我已经在模块和页面中导入了FormsModule：

import { FormsModule } from '@angular/forms';

但仍然出现相同的错误：

Can't bind to 'ngModel' since it isn't a known property of 'ion-select'.

这是视图：

<ion-list>
<ion-list-header>Choix du jeu</ion-list-header>
  <ion-item>
    <ion-label>Mode de jeu</ion-label>
      <ion-select [(ngModel)]="gameMode" placeholder="choix...">
        <ion-select-option *ngFor="let s of games" value="{{s}}">{{s}}</ion-select-option>
      </ion-select>
    </ion-item>
</ion-list>

（ngFor正在工作）

我的module.ts文件：

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';

import { IonicStorageModule } from '@ionic/storage';

import { FormsModule } from '@angular/forms';

import {ScoreModalComponent} from './score-modal/score-modal.component'

@NgModule({
  declarations: [AppComponent, ScoreModalComponent],
  entryComponents: [ScoreModalComponent],
  imports: [BrowserModule,
            IonicModule.forRoot(),
            IonicStorageModule.forRoot(),
            AppRoutingModule,
            FormsModule
  ],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

谢谢！

在离子列表文档中，没有任何双向绑定。但是有事件绑定(click)

如何结合选择或离子选择？包含FormsModule
