如何使用Angular 4 Material对话框实现路由

Question

我想让人们在我的网络应用程序中填写一个查询表格，该表格在模态对话框中打开。首先，我希望人们阅读关于我将要提出的询问的免责声明。

我想在Angular 4中通过路由选择Material对话框，但是如何为对话框设置单独的路由？这甚至可能吗？我正在考虑一种向导结构，在这里您可以读取一个由一个组件定义的页面，然后单击“下一步”并转到下一个组件，直到结束并退出向导？所有这些时间，主要的网络应用程序都无法与之交互。

我的对话框组件的HTML是：

对话框组件的用法如下：

import { Component } from '@angular/core';
import {MdDialog, MdDialogRef} from '@angular/material';

import { CommissionMeDialogComponent } from '../commission-me-dialog/commission-me-dialog.component';

@Component({
  selector: 'app-commission-me',
  templateUrl: './commission-me.component.html',
  styleUrls: ['./commission-me.component.css']
})

export class CommissionMeComponent {

  selectedOption: string;

  constructor(public dialog: MdDialog) {}

  openDialog() {
    let dialogRef = this.dialog.open(CommissionMeDialogComponent);
    dialogRef.afterClosed().subscribe(result => {
      this.selectedOption = result;
    });
  }
}

Answer 1

这里讨论了一些策略（参见“路径路由”选项）：

https://medium.com/ngconf/routing-to-angular-material-dialogs-c3fb7231c177

TL; DR：

你可以通过创建一个只在init上打开模态的虚拟组件来实现：

@Component({
  template: ''
})
export class DialogEntryComponent {
  constructor(public dialog: MatDialog, private router: Router,
    private route: ActivatedRoute) {
    this.openDialog();
  }
  openDialog(): void {
    const dialogRef = this.dialog.open(CommissionMeDialogComponent);
    dialogRef.afterClosed().subscribe(result => {
      this.router.navigate(['../'], { relativeTo: this.route });
    });
  }
}

然后将虚拟组件添加到您的路线：

RouterModule.forRoot([
    {
      path: 'home',
      component: DialogOverviewExample,
      children: [
        {
          path: 'dialog',
          component: DialogEntryComponent
        }
      ]
    }
  ])

Answer 2

您可以像这样设置app.component.html：

<router-outlet></router-outlet>

没有标题，菜单，页脚或任何其他内容。这样，用户就无法选择任何内容，必须专注于当前显示的组件。如果你这样做，那么从技术上讲你不需要它是一个模态对话框。

然后，您将添加如下所示的shell组件：

<pm-menu></pm-menu>

<div class='container'>
    <router-outlet></router-outlet>
</div>

然后你可以将你的“主”应用程序页面路由到这个<router-outlet>，这样他们就可以拥有每个页面上的菜单，页眉，页脚或其他任何内容。

路线看起来像这样：

    RouterModule.forRoot([
        { 
            path: 'wizard', 
            component: WizardComponent,
            children: [
                { path: 'page1', component: Page1Component },
                { path: 'page2', component: Page2Component },
            ]
        },
        {
            path: '',
            component: ShellComponent,
            children: [
                { path: 'welcome', component: WelcomeComponent },
                { path: 'customers', component: CustomerComponent},
                { path: '', redirectTo: 'welcome', pathMatch: 'full' },
            ]
        },
        { path: '**', component: PageNotFoundComponent }
    ])
