我目前正在尝试使用Angular 2,并且无法查看从我创建的服务返回的数据。在开发人员工具中,我看到for (int i = 0; i < x; i++) {
delete[] pixelArray[i];
}
delete[] pixelArray;
api调用触发,但我从未在视图中看到任何数据。有任何想法吗?我错过了一些明显的东西吗?
getSubjects()
import {Injectable} from "angular2/core";
import {Http, Response, HTTP_PROVIDERS} from "angular2/http";
@Injectable()
export class SubjectService{
constructor(public http: Http){
}
getSubject(){
return this.http.request('/subjects.json')
.map(response => response.json())
.subscribe(
res => this.subjects = res,
err => this.logError(err)
);
}
}

移动
Dim rand As Random = New Random(DateTime.Now.Millisecond * DateTime.Now.Second * DateTime.Now.Minute * DateTime.Now.Hour)
从服务到组件应该正常工作
.subscribe(
res => this.subjects = res,
err => this.logError(err)
)
