如何在 *ngFor 中使用服务数据
How consume serve data in *ngFor
这里我创建了一个访问http服务的简单服务,请帮助我如何在*ngFor
中绑定这个服务信息
import { Component } from '@angular/core';
import {Http } from '@angular/http';
import { Injectable } from '@angular/core';
@Injectable()
export class EmployeeService {
constructor(private http: Http) { }
GetStudentData() {
this.http.get('api/Employee').subscribe(response => {
this.student = response.json();
})
}
}
Student.component.ts
GetStudentData() {
var studentser = this.EmpServ.GetStudentData();
//Here How can i Bind
}
她如何将数据保存在一个变量中并在
中使用
您需要return来自服务的数据并绑定到组件内部,
GetStudentData() {
this.http.get('api/Employee').subscribe(response => {
this.student = response.json();
})
return this.student;
}
