如何在加载时调用此角度函数

Question

我有一个异步函数getDataStandard()，需要在单击时执行。我需要不单击而自动完成该函数。怎么做。请帮助我，因为我刚接触离子。

async getDataStandard() {
    let loading = await this.loadingCtrl.create();
    await loading.present();

    this.http.get('https://www.labourguide.co.za/LabourguideApi/index.php?q=mostRecentPublications').pipe(
      finalize(() => loading.dismiss())
    )
    .subscribe(data => {
console.log("Testing ...............1");
      this.data = data;
console.log(data);
console.log("Testing ..............2");
    }, err => {
      console.log('JS Call error: ', err);
    });
  }

这是离子部分

 <ion-button expand="block" (click)="getDataStandard()">getDataStandard</ion-button>

Answer 1

叫你 ngOnInit

export class App implements OnInit{
  constructor(){
     //called first time before the ngOnInit()
  }

  ngOnInit(){

    this.getDataStandard() ;

  }
}
