I am trying to find a way to determine if I am on the home page and then take a specific action, without doing so on other pages. This component is imported on every page.
Is there a method to detect whether I am on the home page from within this component?
Thank you
Here's a suggestion for you to try:
import { Router } from '@angular/router';
export class MyComponent implements OnInit {
constructor(private router:Router) { ... }
ngOnInit() {
let currentUrl = this.router.url; /// get the current URL
// Add your logic here to determine if it is the home page.
}
}
Give it a shot
import { Component } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';
@Component({...})
export class MyComponent {
constructor(private router:Router) {
router.events.subscribe(event => {
if (event instanceof NavigationEnd ) {
console.log("current URL is:", event.url); // event.url contains the current URL
// Implement your logic here
}
});
}
}
Utilize the following snippets from the native window object.
console.log('Current URL:' + window.location.href);
console.log('Pathname:' + window.location.pathname);
console.log('Host Server:' + window.location.host);
console.log('Hostname Address:' + window.location.hostname);
console.log('Resource Origin:' + window.location.origin);
console.log('Connection Port:' + window.location.port);
console.log('Query Parameters:' + window.location.search);
IMPORTANT: AVOID IMPLEMENTING THIS IN SERVER-SIDE RENDERING
An effective way to retrieve the current path in Angular is by utilizing the Location Service.
import { Location } from '@angular/common';
Simply access the path using the following code:
location.path();
To obtain the full URL, utilize the LOCATION instance in the following manner:
([Location][1])location.href = https://example-domain.com/#/login?user=superman
& if a relative URL is preferred, utilize the ROUTER instance like so:
this.router.url = login?user=superman
Refer to the code snippet below for Angular 4 implementation:
constructor( private router: Router) {
console.log(this.router.url);
/**
* login?user=superman
*/
console.log(location.href);
/**
* https://example-domain.com/#/login?user=superman
*/
}
Although I intended to provide an answer to this question, it seems that BigBrother has already shared the same response as mine. My answer caters to individuals who utilize "#" in their URL, as some router location codes only return "/".
Here is a snippet of code from a project I am working on:
this.router.events.subscribe((event) => {
if(event instanceof NavigationEnd) {
this.currentPage = event.url;
if ( event.url != '/admin') {
setTimeout(()=>{
this.modalRef = this.modalService.show(ModalSurveyComponent,this.config);
}, 3000);
}
}
});
This popover will be displayed only when the current route is not "/admin".
import { RouterStateSnapshot } from '@angular/router';
constructor(private routeState: RouterStateSnapshot) {
console.log("Displaying Current Url Path", routeState);
}
