这是我的打字稿代码
export class FailedPage {
failedjobs: Array<any> = [];
constructor(public navCtrl: NavController,
public navParams: NavParams, public jobfailList: JobActionsProvider) {
}
ionViewDidLoad() {
console.log('FailedPage');
// getting jobs from job-actions file and displaying
this.jobfailList.getfailedjobList().then((data) => {
console.log('displaying failed job list');
for (let values of data) {
this.failedjobs.push(values);
}
});
}
}
我正面临错误
未捕获(承诺):TypeError:无法读取的属性“ length” 未定义的TypeError:无法读取位于的未定义属性“长度” failed.ts:24
这里的24行是for (let values of data)
我该如何解决?
答案 0 :(得分:0)
api的响应可以是data.data,它取决于您的后端
