Angular 2:将数据传递给路由？

Question

我正在研究这个angular2项目,我用它ROUTER_DIRECTIVES来从一个组件导航到另一个组件.

有2个组件.即PagesComponent&DesignerComponent.

我想从PagesComponent导航到DesignerComponent.

到目前为止它的路由正确但我需要传递pageObject,因此设计人员可以加载该页面对象本身.

我尝试使用RouteParams但它获取页面对象undefined.

下面是我的代码:

pages.component.ts

import {Component, OnInit ,Input} from 'angular2/core';
import { GlobalObjectsService} from './../../shared/services/global/global.objects.service';
import { ROUTER_DIRECTIVES, RouteConfig } from 'angular2/router';
import { DesignerComponent } from './../../designer/designer.component';
import {RouteParams} from 'angular2/router';

@Component({
    selector: 'pages',    
    directives:[ROUTER_DIRECTIVES,],
    templateUrl: 'app/project-manager/pages/pages.component.html'
})
@RouteConfig([
  { path: '/',name: 'Designer',component: DesignerComponent }      
])

export class PagesComponent implements OnInit {
@Input() pages:any;
public selectedWorkspace:any;    
constructor(private globalObjectsService:GlobalObjectsService) {
    this.selectedWorkspace=this.globalObjectsService.selectedWorkspace;                    
}
ngOnInit() { }   
}

在html中,我正在做以下事情:

<scrollable height="300" class="list-group" style="overflow-y: auto; width: auto; height: 200px;" *ngFor="#page of pages">
    {{page.name}}<a [routerLink]="['Designer',{page: page}]" title="Page Designer"><i class="fa fa-edit"></i></a>
</scrollable>

在DesignerComponent构造函数中,我完成了以下操作:

constructor(params: RouteParams) {
    this.page = params.get('page');
    console.log(this.page);//undefined
}

到目前为止,它正确地路由到设计器,但当我试图访问page设计器中的对象然后它的显示undefined.有解决方案吗

Answer 1

您不能使用路由器参数传递对象,只能传递字符串,因为它需要反映在URL中.无论如何,使用共享服务在路由组件之间传递数据可能是更好的方法.

旧路由器允许通过data但新的(RC.1)路由器尚未通过.

data重新介绍了RC.4 如何使用路由时如何在Angular 2组件中传递数据？

它的角度变化2.1.0

在something.module.ts中

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { BlogComponent } from './blog.component';
import { AddComponent } from './add/add.component';
import { EditComponent } from './edit/edit.component';
import { RouterModule } from '@angular/router';
import { MaterialModule } from '@angular/material';
import { FormsModule } from '@angular/forms';
const routes = [
  {
    path: '',
    component: BlogComponent
  },
  {
    path: 'add',
    component: AddComponent
  },
  {
    path: 'edit/:id',
    component: EditComponent,
    data: {
      type: 'edit'
    }
  }

];
@NgModule({
  imports: [
    CommonModule,
    RouterModule.forChild(routes),
    MaterialModule.forRoot(),
    FormsModule
  ],
  declarations: [BlogComponent, EditComponent, AddComponent]
})
export class BlogModule { }

获取编辑组件中的数据或参数

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';
@Component({
  selector: 'app-edit',
  templateUrl: './edit.component.html',
  styleUrls: ['./edit.component.css']
})
export class EditComponent implements OnInit {
  constructor(
    private route: ActivatedRoute,
    private router: Router

  ) { }
  ngOnInit() {

    this.route.snapshot.params['id'];
    this.route.snapshot.data['type'];

  }
}
