我有很多組件。我在模塊中聲明我的組件。 app.module。將params從一個組件傳遞到另一個angular2
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
// Material 2
import { MdCoreModule } from '@angular2-material/core';
import { MdButtonModule } from '@angular2-material/button';
import { MdButtonToggleModule } from '@angular2-material/button-toggle';
import { MdCardModule } from '@angular2-material/card';
import { MdRadioModule } from '@angular2-material/radio';
import { MdCheckboxModule } from '@angular2-material/checkbox';
import { MdTooltipModule } from '@angular2-material/tooltip';
import { MdInputModule } from '@angular2-material/input';
import { MdToolbarModule } from '@angular2-material/toolbar';
import { MdTabsModule } from '@angular2-material/tabs';
import { MdSidenavModule } from '@angular2-material/sidenav';
// import { MdMenuModule } from '@angular2-material/menu';
// import { TabsModule } from 'ng2-tabs';
import { AppComponent } from './app.component';
import "hammerjs";
import { routing, appRoutingProviders } from './app.routes';
import { DashboardComponent } from './dashboard/dashboard.component';
import { IndexComponent } from './index/index.component';
import { LoginComponent } from './login/login.component';
import { NotFoundComponent } from './not-found/not-found.component';
import { IndexService } from './services/index.service';
import { ErrorMessageComponent } from './error-message/error-message.component';
import { MenuComponent } from './menu/menu.component';
import { PageAnalysisComponent } from './page-analysis/page-analysis.component';
import { SettingsComponent } from './settings/settings.component';
import { SiteVsSiteComponent } from './site-vs-site/site-vs-site.component';
import { SidenavComponent } from './sidenav/sidenav.component';
@NgModule({
declarations: [
AppComponent,
DashboardComponent,
IndexComponent,
LoginComponent,
NotFoundComponent,
ErrorMessageComponent,
MenuComponent,
PageAnalysisComponent,
SettingsComponent,
SiteVsSiteComponent, SidenavComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
routing,
MdCoreModule, MdCardModule, MdButtonModule, MdRadioModule,
MdCheckboxModule, MdTooltipModule,MdInputModule, MdToolbarModule,MdButtonToggleModule,
MdTabsModule,MdSidenavModule
],
providers: [appRoutingProviders,IndexService ],
bootstrap: [AppComponent]
})
export class AppModule {
}
所以,現在我想將數據從組件Dashbord傳遞給PageAnalysisComponent組件。我該怎麼做?這裏是組件儀表板的代碼:
import { Component, Input, Output, OnInit, ViewEncapsulation } from '@angular/core';
import { Params } from '../services/index.service';
import { ActivatedRoute, Router } from '@angular/router';
@Component({
selector: 'app-dashboard',
templateUrl: './dashboard.component.html',
styleUrls: ['./dashboard.component.css'],
encapsulation: ViewEncapsulation.None
})
export class DashboardComponent implements OnInit {
data: any;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.route
.params
.subscribe(v => this.data = "hello");
}
}
and PageAnalysisComponent component:
import { Component, Input, Output, OnInit } from '@angular/core';
import { Params } from '../services/index.service';
import { ActivatedRoute, Router } from '@angular/router';
@Component({
selector: 'app-page-analysis',
templateUrl: './page-analysis.component.html',
styleUrls: ['./page-analysis.component.css']
})
export class PageAnalysisComponent implements OnInit {
data: any;
constructor(private route: ActivatedRoute) { }
ngOnInit() {
//I woild like to have here data
}
}
如何將數據從dashbord傳輸到PageAnalysisComponent組件。 這裏有可能嗎?
