Answer 1

您可以使用基本的javascript警报来满足基本需求。

警报（＆＃34;成功，团队删除＆＃34;）;

也可以使用确认框查看https://www.w3schools.com/js/js_popup.asp

在您的情况下，它将具有以下

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，您可以发出成功消息。

在模块

中

import {MessagesModule} from 'primeng/primeng';

在 HTML

中

 <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>

在组件

中

export class MessagesDemo {

msgs: Message[] = [];

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


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

}
