当我想要设置新的loadingController时，LoadingOption出错

2 年前

嗨，我是Ionic的新手，当我想要创建新的loadingScreen时，我有这个错误 .

Argument of type '{ content: string; }' is not assignable to parameter 
of type 'LoadingOptions'.
Object literal may only specify known properties, and 'content' does not exist in type 'LoadingOptions'.

我看documentation，我觉得语法很好 .

const loading = await this.loadingController.create({
        content: 'Please wait...',
    });
    await loading.present();

看起来他们的文档已经过时，这里是他们代码中的接口定义：

https://github.com/ionic-team/ionic/blob/master/core/src/components/loading/loading-interface.ts

export interface LoadingOptions {
  spinner?: SpinnerTypes | null;
  message?: string;
  cssClass?: string | string[];
  showBackdrop?: boolean;
  duration?: number;
  translucent?: boolean;
  animated?: boolean;

  mode?: Mode;
  keyboardClose?: boolean;
  id?: string;

  enterAnimation?: AnimationBuilder;
  leaveAnimation?: AnimationBuilder;
}

如您所见，没有 content ，它已被重命名为 message .

暂时没有评论！
