Angular(4)：分别禁用整个表单(组)而不是每个输入？

form: formGroup;

this.form.disable();

在NgForm的情况下,你可以这样写’创建plunker

<form #f="ngForm" (ngSubmit)="onSubmit(f)" novalidate>
  <input name="first" ngModel required #first="ngModel">
  <input name="last" ngModel>
  <button>Submit</button>
</form>

<button (click)="disable(f)">Disable form</button>



 disable(f) {
    f.form.disable()
  }
