Example 1: Below is the example code that illustrates the use of Angular PrimeNG Breadcrumb Events. In this example, we will learn about onItemClick and display alerts when the breadcrumb is clicked.
- app.component.html:
HTML
< h2 style = "color: green;" >w3wiki</ h2 > < h3 >Angular PrimeNG Breadcrumb Events</ h3 > < p-breadcrumb [model]="gfg" (onItemClick)="callAlert()"> </ p-breadcrumb > |
- app.component.ts:
Javascript
import { Component } from "@angular/core" ; import { MenuItem } from "primeng/api" ; @Component({ selector: "app-root" , templateUrl: "./app.component.html" }) export class AppComponent { gfg: MenuItem[] = []; ngOnInit() { this .gfg = [ { label: "AngularJS" }, { label: "ReactJS" }, { label: "HTML" }, { label: "JavaScript" }, { label: "PrimeNG" } ]; } callAlert() { alert( "Hi Geek!
