我的页面布局看起来像这个
-----------------------------------------------------
HEADER MENU --> Page1 <Page2>
-----------------------------------------------------
Page1 Child1 |
Page1 Child2 | MAIN CONTENT
Page1 Child2 |
----------------------------------------------------
FOOTER
----------------------------------------------------
如果用户点击Page1我想刷新左边的菜单列出Page1的子项,如果我点击第2页比我要刷新菜单列表并显示第2页的子项
这是我的路由器当前的样子,但我收到了错误
core.umd.js:3070 EXCEPTION: Uncaught (in promise): Error: Cannot match any routes. URL Segment: ''
错误:无法匹配任何路线。网址细分:'' 在ApplyRedirects.noMatchError

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { Page1Component } from './Page1/Page1.component';
import { Page1Child1Component } from './Page1/Page1Child1/Page1Child1.component';
import { Page2Component } from './Page2/Page2.component';
import { RouterModule } from '@angular/router';
@NgModule({
imports: [BrowserModule,
RouterModule.forRoot([
{ path: '', redirectTo: 'Page1', pathMatch: 'full' },
{
path: 'Page1', component: Page1Component,
children: [
{ path: '', redirectTo: 'Page1Child1', pathMatch: 'full' },
{ path: 'Page1Child1', component: Page1Child1Component }
]
},
{ path: 'Page2', component: Page2Component }
])
],
declarations: [AppComponent, Page1Component, Page2Component, Page1Child1Component],
bootstrap: [AppComponent]
})
export class AppModule { }
截图UI看起来如预期,但控制台窗口中出现错误
core.umd.js:3070 EXCEPTION: Uncaught (in promise): Error: Cannot find primary outlet to load 'Page1Child1Component'
Error: Cannot find primary outlet to load 'Page1Child1Component'
at getOutlet
Page1.component
import { Component } from '@angular/core';
@Component({
selector: 'Page1',
template: `<h1>This is from Page1 </h1>
<ul>
<li *ngFor="let item of links; let i = index">
<a [routerLink]="['Page1Child1']" routerLinkActive="active" outlet:"main">{{item}}</a>
</li>
</ul>
`
})
export class Page1Component {
links: any[] = [
'Page1 Child1',
'Page1 Child2'
];
}
现在,只要我更新Pag1Component以使用命名出口,它就会抛出解析错误。
{{项}}
这只是吹出整个页面而没有显示任何内容,控制台窗口会抛出解析错误
错误:(SystemJS)模板解析错误:(...)(匿名函数)@(索引):20ZoneDelegate.invoke @ zone.js:232Zone.run @ zone.js:114(匿名函数)@ zone.js: 502ZoneDelegate.invokeTask @ zone.js:265Zone.runTask @ zone.js:154drainMicroTaskQueue @ zone.js:401ZoneTask.invoke @ zone.js:339
有更好的方法吗
答案 0 :(得分:0)
因为孩子们没有根路径。当Page1
路径首次加载时,它有一个路由器出口,它尝试加载子路由,但Page1
有一个配置了''
的路由。当你转到Page1
网址时,这是必需的。如果您转到Page1/Page1Child1
,它会知道该组件,但Page1
(需要映射到''
)并不存在
所以只需将重定向添加到默认子路径
children: [
{ path: '', redirectTo: 'Page1Child', pathMatch: 'full' }
{ path: 'Page1Child1', component: Page1Child1Component}
]
