我目前深化發展的角4個app.I使用web服務的REST類型正在從DB.So得到i的數據由被稱爲UsersListService前端服務,其具有返回到可觀察到的一個方法,該方法我在compnent.I訂閱想要的組件的屬性的用戶更改爲Web服務,但遺憾的是該組件的屬性總是被設置爲它返回的數據的默認value.So一旦頁面加載我被返回的數據web服務,但一旦我做搜索或paginetion用戶設置爲它的默認值「1」,「2」,「3」。改變組件的屬性未訂閱方法
這是服務方法:
getUserList(){
//this method is returning the items
return this.http.get(this.usersUrl)
.map(res => {
this.users=res['items'];
return this.users;
});
}
這是我的組件
import {User} from '../../auth/shared/user';
import {CreateUserComponent} from '../create-user/create-user.component';
import {UpdateUsersCredentialsComponent} from '../update-users-credentials/update-users-credentials.component';
import { Component, OnInit, AfterViewInit } from '@angular/core';
import { MdDialog } from '@angular/material';
import{UsersListService} from '../shared/users-list.service'
@Component({
selector: 'vr-users-list',
templateUrl: './users-list.component.html',
styleUrls: ['./users-list.component.scss']
})
export class UsersListComponent implements OnInit,AfterViewInit {
private users:any[]=["1","2","3"];
constructor(public dialog: MdDialog,private userListService: UsersListService) { }
ngOnInit() {
this.userListService.getUserList().subscribe (
data =>{
console.log("those are data "+data.length);
this.users=data;
});
}
ngAfterViewInit(){
this.userListService.getUserList().subscribe (
data =>{
console.log("those are data "+data.length);
this.users=data;
});
}
openUsersDetails() {
this.dialog.open(UpdateUsersCredentialsComponent);
}
openCreateUser() {
this.dialog.open(CreateUserComponent);
}
}
這是我的HTML

<vr-breadcrumbs [currentPage]="'users'" ></vr-breadcrumbs>
<div fxLayout="colomun" fxLayoutAlign="end">
