单击 md 对话框按钮后执行特定组件

Question

我在页面的左侧面板上有 8 个图表图像。当我将这些图像拖放到右侧面板时，我会显示 MD 对话框。在 md 对话框中，我在下拉菜单中显示列表。

我提到了

从下拉列表中选择 select 项后，我单击 md 对话框的 "Yes" 按钮。

在此按钮上单击我要执行基于项目 selection 的特定组件。例如，如果我 select "Heap Memory" 那么我想执行 "HeapMemoryComponent" 等等

routing.ts

import  {ModuleWithProviders} from '@angular/core';
import {Routes,RouterModule} from '@angular/router';

import {AppComponent} from './app.component';
import {HeapMemoryComponent} from './aem-down-time-graph/aem-down-time-graph.component'
const appRoutes:Routes = [
{
 path: 'abc',
 component: HeapMemoryComponent
}
];
export const routing:ModuleWithProviders = RouterModule.forRoot(appRoutes);

左面板组件

import { Component, OnInit } from '@angular/core';
import {LeftpanelService} from "../leftpanel.service"
import {Leftpanel} from "../leftpanel";
import {MdDialog} from "@angular/material";
import {MdDialogRef} from "@angular/material";
import { Routes, RouterModule } from '@angular/router';
import {ServersListDialogComponent} from "../servers-list-dialog/servers-list-dialog.component";
@Component({
selector: 'app-leftpanel',
templateUrl: './leftpanel.component.html',
styleUrls: ['./leftpanel.component.css']
})
export class LeftpanelComponent implements OnInit {
 dialogRef: MdDialogRef<ServersListDialogComponent>;
 leftpanels:Leftpanel[];
 receivedData:Array<any> = [];

 constructor(
   public dialog: MdDialog,private service:LeftpanelService,public router:Router
 ) { }

 ngOnInit() {
   this.service.getLeftpanels().subscribe(lst =>this.leftpanels=lst);
 }

 transferDataSuccess($event) {
 this.receivedData.push($event.dragData);
 this.openDialog();
 }
 openDialog() {
  this.dialogRef = this.dialog.open(ServersListDialogComponent, {
    disableClose: false
  });

  this.dialogRef.afterClosed().subscribe(result => {
    console.log('result: ' + result);
    this.dialogRef = null;
    if(result.componentName == "HeapMemoryComponent"){
      this.router.navigate(['HeapMemoryComponent']);
    }
  });
 }

}

单击 "Yes" 后，我想根据项目 selection 执行以下组件。

@Component({
 selector: 'app-mainpanel',
 templateUrl: './heap-memory.component.html',
 styleUrls: ['heap-memory.component.css']
})
export class  HeapMemoryComponent implements OnInit {
constructor() {
 console.log("HeapMemoryComponent object is created...");
}

ngOnInit() {
 console.log("HeapMemoryComponent ....");
}

}

HeapMemoryComponent 上面有一些 html 响应，上面的这个组件将有服务。我将有多个组件，如上所示。

我不知道如何像上面的特定组件那样执行？请给我解决方案

如果您想在对话框结果后导航到特定组件，您可以这样做：

import {Router} from "@angular/router";
...
constructor(public router:Router..){}

this.dialogRef.afterClosed().subscribe(result => {
    console.log('result: ' + result);
    this.dialogRef = null;
    //based on result
    if(result.componentName == "HeapMemoryComponent"){
      this.router.navigate(['abc']);
    }
  });

注意result.componentName部分是我补的，不知道你回调的结果是什么
