export class myclass implements OnInit {
private outagesList;
private outageArray;
constructor(private outages: OutagesService){}
ngOnInit(){
this.outages.getOutagesList().subscribe((data) => {
this.outagesList = data;
this.outagesList.forEach( function (arrayItem)
{
this.outageArray.push(arrayItem["title"]);
});
)
}
如果我尝试将数据推送到 outageArray，它会抛出 ERROR TypeError: Cannot read property 'outageArray' of undefined
我怎样才能避免这个错误？我需要将此 outageArray 值访问到 html。
