Ng2.x 常見錯(cuò)誤總結(jié)。

1.EXCEPTION:... caused by: If ngModel is used within a form tag, either the name attribute must be set or the form control must be defined as 'standalone' in ngModelOptions.

原因：Angular2規(guī)定，當(dāng)在表單中使用 [(ngModel)] 時(shí)，必須要定義 name 屬性。沒有name屬性就會(huì)報(bào)上面的錯(cuò)誤

解決辦法：給表單標(biāo)記添加name屬性即可

2.加載的模板不顯示 Error: Uncaught (in promise): Failed to load xxx.html

moduleId - ES/CommonJS module id of the file in which this component is defined

@Component({
  moduleId: module.id,    //加上這句就可以了
  selector: 'xxx-xxx',
  templateUrl: 'xxx.component.html'  //外部模板
})
