我想使用Angular 2创建动态标签导航系统。
基本上我想首先显示一个包含单个组件的选项卡,其中包含可点击的对象(如链接,按钮......)。
我希望点击其中一个链接添加一个新标签,然后点击每个标签(初始标签和新创建的标签)会在下方的显示区域(路由器插座)中显示相应的组件。
这是我到目前为止所尝试的:
app.component.ts(根组件和“标签容器”):
import { Component, OnInit } from '@angular/core';
import { TabComponent } from './tab/tab.component';
import { FirstComponent } from './test/first.component';
import { SecondComponent } from './test/second.component';
import { ThirdComponent } from './test/third.component';
import { ROUTER_DIRECTIVES } from '@angular/router';
@Component({
selector: 'my-app',
templateUrl: './app/app.component.html',
directives: [TabComponent, ROUTER_DIRECTIVES, FirstComponent, SecondComponent, ThirdComponent],
})
export class AppComponent implements OnInit{
tabList: any[];
constructor() {}
ngOnInit() {
this.tabList = [
{
name: 'link 1',
link: "/comp1"
},
{
name: 'link 2',
link: "/comp2"
},
{
name: 'link 3',
link: "/comp3"
}
]
}
}
app.component.html:
<h1>Tabs container</h1>
<div>
<nav>
<tab *ngFor="let tab of tabList" [name]="tab.name" [link]="tab.link"></tab>
</nav>
</div>
<div>
<router-outlet></router-outlet>
</div>
每个标签由tab.component.ts:
表示
import { ROUTER_DIRECTIVES, Router } from '@angular/router';
import { Component, OnInit, Input } from '@angular/core';
@Component({
selector: 'tab',
templateUrl: './app/tab/tab.component.html',
directives: [ROUTER_DIRECTIVES]
})
export class TabComponent implements OnInit {
@Input() name: string;
@Input() link: string;
@Input() param: string;
targetArray: Array<any>;
constructor(private router: Router) {}
ngOnInit() {
}
}
哪个模板是tab.component.html:
<a [routerLink]='link'>{{name}}</a>
这是app.routes.ts文件:
import { provideRouter, RouterConfig } from '@angular/router';
import { TabComponent } from './tab/tab.component';
import { FirstComponent } from './test/first.component';
import { SecondComponent } from './test/second.component';
import { ThirdComponent } from './test/third.component';
export const routes: RouterConfig = [
{
path: '',
component: TabComponent
},
{
path: 'comp1',
component: FirstComponent
},
{
path: 'comp2',
component: SecondComponent
},
{
path: 'comp3',
component: ThirdComponent
},
];
export const APP_ROUTER_PROVIDERS = [
provideRouter(routes)
];
例如,first.component.ts(SecondComponent和ThirdComponent类似):
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'first',
template: `<h1>First</h1>
<button (click)="addTab()">Display child</button>
`
})
export class FirstComponent implements OnInit {
constructor() {}
ngOnInit() {
}
addTab(){
}
}
我想将标签创建逻辑放在addTab()方法中,基本上将一个元素添加到app.component.ts中的tabList数组并获取所需的行为,但我不知道如何从这个传输数据组件到app.component.ts。
我也对任何不同的方法和建议持开放态度。

您可以将路由器注入您的组件,然后使用 config 方法配置动态链接。
router.config([
{ 'path': '/', 'component': IndexComp },
{ 'path': '/user/:id', 'component': UserComp },
]);
可以找到路由器服务的文档here。
