Angular 2：将数据传递给路由？

问题描述

我正在研究这个angular2项目，我在其中使用 ROUTER_DIRECTIVES 从一个组件导航到另一个组件。

I am working on this angular2 project in which I am using ROUTER_DIRECTIVES to navigate from one component to other.

有2个组成部分。即 PagesComponent & DesignerComponent 。

There are 2 components. i.e. PagesComponent & DesignerComponent.

我想从PagesComponent导航到DesignerComponent。

I want to navigate from PagesComponent to DesignerComponent.

到目前为止它的路由正确但我需要传递页面对象，因此设计人员可以自己加载该页面对象。

So far its routing correctly but I needed to pass page Object so designer can load that page object in itself.

我尝试使用RouteParams但它获取页面对象 undefined 。

I tried using RouteParams But its getting page object 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，我正在做以下事情：

In the html, I am doing following:

<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：

In the DesignerComponent constructor I have done the following:

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，但当我尝试访问设计器中的页对象时，它显示未定义。
任何解决方案？

So far its routing correctly to designer, but when I am trying to access page Object in designer then its showing undefined.Any solutions?

推荐答案

你不能使用路由器参数传递对象，只能传递字符串，因为它需要被反映在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。

You can't pass objects using router params, only strings because it needs to be reflected in the URL. It would be probably a better approach to use a shared service to pass data around between routed components anyway.

旧路由器允许传递数据但是新的（ RC.1 ）路由器还没有。

The old router allows to pass data but the new (RC.1) router doesn't yet.

更新

数据重新引入 RC.4
