Answer 1

您需要导入 FormsModule

import { FormsModule, ReactiveFormsModule } from '@angular/forms'

@NgModule({
imports: [ BrowserModule ,FormsModule],
declarations: [ App ],
bootstrap: [ App ]
})

Answer 2

对于复选框输入，您可以使用[checked]代替[(ngModel)] 此外，您可以使用(change)代替([ngModelChange)]

<input class="checkbox binning-checkbox" type="checkbox"  
            (change)="select(item)" [checked]="item.selected">
