我正在尝试获取编辑目的的详细信息,但我不确定如何使用observables可以帮助我的问题是编辑功能。
@Component({
selector: 'Search',
templateUrl: './components/search/search.html',
directives: [REACTIVE_FORM_DIRECTIVES],
providers : [GetSocietyList],
})
export class Search {
property:any = 'Add';
data: string;
form:any;
prop: string = 'connenct';
details: IStudent1[];
details1: IStudent2[];
constructor(fbld: FormBuilder,public http: Http,private _profileservice:GetSocietyList) {
this.details = [];
this.http = http;
this._profileservice.getSocietyList()
.subscribe(details => this.details = details);
console.log(this.details);
this.form = fbld.group({
name: [''],
age: ['', Validators.required],
class: ['', Validators.required],
grade: ['', Validators.required]
});
}
edit(id): any {
//console.log(id);
this.property = 'update';
var headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded')
this.http.get('http://localhost/a2server/index.php/profile/editprofiledb/' + id, { headers: headers })
.subscribe(response => {
if (response.json().error_code == 0) {
this.details = <IStudent2[]>response.json().data;
} else {
this.details = <IStudent2[]>response.json().data;
}
} )}

答案 0 :(得分:1)
this._profileservice.getSocietyList()
.subscribe(details => this.details = details);
console.log(this.details);
这将始终记录undefined
,因为您在订阅observable后立即进行了日志记录。您需要等待请求完成以查看数据:
this._profileservice.getSocietyList()
.subscribe(details => {
this.details = details;
console.log(this.details);
});
因此,您的数据提取最有可能起作用,您只是想过于急切地记录它。
