您可以使用basic基本需求的JavaScript警报。

alert（“Success，team deleted”）;

也可以使用确认对话框看到https://www.w3schools.com/js/js_popup.asp

在你的情况下，将具有以下

deleteTeam(team){ 
var teams = this.myTeams; 
var length = teams.length; 
var i;  
var indexObj; 
var index; 

for(i = 0; i < length; i ++){ 
    if(team.name===teams[i].name){ 
     console.log(team.name); 
     indexObj = teams[i]; 
     index = teams.indexOf(indexObj); 
     teams.splice(index, 1); 
     localStorage.setItem("storedTeams", JSON.stringify(teams)); 

     alert("Success! Team deleted"); 
    } 
} 

Answer 2

使用PrimeNg你可以给成功的消息。

在模块

import {MessagesModule} from 'primeng/primeng'; 

在HTML

<p-messages [value]="msgs"></p-messages> 

<div> 
<button type="button" pButton (click)="showSuccess()" label="Success" class="ui-button-success"> 
</button> 
<button type="button" pButton (click)="clear()" icon="fa-close" style="float:right" label="Clear"> 
</button> 
</div> 

在部件

export class MessagesDemo { 

msgs: Message[] = []; 

showSuccess() { 
    this.msgs = []; 
    this.msgs.push({severity:'info', summary:'Info Message', detail:'PrimeNG rocks'}); 
} 


clear() { 
    this.msgs = []; 
} 

}
