Question

因此，我使用选项卡页面上的注销按钮功能导航回到登录页面。不幸的是，当用户已经登录并注册时，我无法单击“退出”按钮

我尝试过身份验证功能来导航回登录

tabs.page.ts

import {Component, OnInit, ViewChild} from '@angular/core';
import {UserService} from '../user.service';
import {AngularFireAuth} from '@angular/fire/auth';
import { Router} from '@angular/router'
import {AngularFirestore} from '@angular/fire/firestore'

@Component({
selector: 'app-tabs',
templateUrl: 'tabs.page.html',
styleUrls: ['tabs.page.scss'],
})
export class  TabsPage implements OnInit {
constructor(
public afAuth: AngularFireAuth,
public router: Router,
public afstore: AngularFirestore
 ) {}

ngOnInit()  {
}
 async logout() {
 try { 
 this.afAuth.auth.signOut();
this.router.navigate(['/loginPage']);
} catch (error) {
 console.log('Error', error);
}
}
}

tabs.page.html

 <ion-item>
 <ion-button ion-button color="danger"   (click)="logout()" full>signOut
</ion-button>
</ion-item>

您需要在其中放置<DataGridTextColumn Header="{lex:Loc material}" Binding="{Binding Material}" Width="Auto" MinWidth="75" ToolTipService.ShowDuration="99999" ToolTipService.InitialShowDelay="0"> <DataGridTextColumn.CellStyle> <Style TargetType="DataGridCell" BasedOn="{StaticResource MaterialDesignDataGridCell}"> <Setter Property="ToolTip"> <Setter.Value> <Image Source="{Binding ProductImage}" Width="250" /> </Setter.Value> </Setter> <Style.Triggers> <DataTrigger Binding="{Binding ProductImageExists}" Value="False"> <Setter Property="ToolTip" Value="{x:Null}" /> </DataTrigger> </Style.Triggers> </Style> </DataGridTextColumn.CellStyle> </DataGridTextColumn>和Item Type Price 1 Price 2 Price 3 1 A 400 200 -46 1 B 500 250 -62 1 C 600 300 0。

  Unique_Items variable  value
           1 A  Price 1    400
           1 B  Price 1    500
           1 C  Price 1    600
           1 A  Price 2    200
           1 B  Price 2    250
           1 C  Price 2    300
           1 A  Price 3    -46
           1 B  Price 3    -62
           1 C  Price 3      0

或者，您也可以采用await的写作风格：

async

否则，路由器将在async logout() { try { // add await here: await this.afAuth.auth.signOut(); this.router.navigate(['/loginPage']); } catch (error) { console.log('Error', error); } }完成运行之前重定向到下一页。

注销按钮不起作用
