Question

我使用angular2路由器为我的应用程序配置路由这是我的代码片段。

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
import { AppComponent } from './app.component';
import { DashboardComponent } from './dashboard/dashboard.component';
import { UpdateprofileComponent } from './updateprofile/updateprofile.component';
import { ChangepasswordComponent } from './changepassword/changepassword.component';
import { CookieService } from 'angular2-cookie/services/cookies.service';
import { PathLocationStrategy, LocationStrategy, HashLocationStrategy } from '@angular/common';

const routes = [
  {
    path: 'dashboard',
    component: DashboardComponent
  },
  { path: 'updateprofile', component: UpdateprofileComponent },
  { path: 'changepassword', component: ChangepasswordComponent },
  // Not found
  { path: '**', redirectTo: 'dashboard' }
];

@NgModule({
  declarations: [
    AppComponent,
    DashboardComponent,
    UpdateprofileComponent,
    ChangepasswordComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    NgbModule.forRoot(),
    RouterModule.forRoot(routes, { useHash: true })
  ],
  providers: [CookieService],
  bootstrap: [AppComponent]
})
export class AppModule { }

header.component.html

<header>
   <select [(ngModel)]="userOperationType" (ngModelChange)="fnSetOperationType(userOperationType)" class="col-md-12 select-style">
                        <option value="dashboard">Account Administration</option>
                        <option value="changepassword" selected>Change Password</option>
                        <option value="updateprofile">Your Profile</option>
                    </select>
</header>

header.component.ts

import { Component, OnInit,Input } from '@angular/core';
import { UserDetailsService } from '../services/user-details.service';
import { Router } from '@angular/router';

@Component({
  selector: 'app-header',
  templateUrl: './header.component.html',
  styleUrls: ['./header.component.scss'],
  providers: [UserDetailsService]
})
export class NvidiaHeaderComponent implements OnInit {


  constructor() { }


  fnSetOperationType(routeName) {
    this.route.navigate([routeName]);

  }
}

的index.html

<!doctype html>
<html>

<head>
  <meta charset="utf-8">
  <title>Angular2Routing</title>
  <base href="./">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
</head>
<body>
  <app-root>loading...
  </app-root>
  <script type = "text/javascript" >
history.pushState(null, null, '/#/dashboard');
window.addEventListener('popstate', function(event) {
history.pushState(null, null, '/#/dashboard');
});
</script>
</body>

</html>

这是我在app.module.ts中的路由。导航到更改密码路由后，我的网址为http://localhost:4200/#/changepassword。当我刷新我的页面或在新标签页中打开此网址时，我的网址会重定向到http://localhost:4200/#/dashboard（默认路由）。

我需要在刷新页面后获得相同的路线，或者如果我在另一个标签中复制粘贴路线，我需要获得相应的路线。

请帮帮我。提前致谢。

Answer 1

尝试将默认路线重定向到信息中心，而不是useAsDefault: true：

{ path: '', redirectTo: 'dashboard', pathMatch: 'full' },
{
    path: 'dashboard',
    component: DashboardComponent,
    //useAsDefault: true //remove this
}

Answer 2

我在index.html中犯了一个小错误。我删除了以下脚本。我用它来清除浏览器历史记录。

<script type = "text/javascript" >
history.pushState(null, null, '/#/dashboard');
window.addEventListener('popstate', function(event) {
history.pushState(null, null, '/#/dashboard');
});
</script>

它像魅力一样！谢谢你的帮助。:)）

刷新路由使用angular2路由器指向默认路由
