Angular 2 - Redirect to an external URL and open in a new tab
I'm trying to Open a new page when user clicks on a link. I can't use Angular 2 Router, because it doesn't have any functionalities to redirect to an external URL.
so, i'm using window.location.href="...";
html code:
<button (click)="onNavigate()">Google</tn-submenu-link>
typescript code:
onNavigate(){
//this.router.navigateByUrl("https://www.google.com");
window.location.href="https://www.google.com";
}
But how can I open it in a new tab? when using window.location.href ?
window object inside a component (while you can get-away with using the window global, it's preferred to perform platform-specific tasks (like using the window object, which differs between browsers) using an Angular Service.
onNavigate(){
window.open("https://www.google.com", "_blank");
}
One caveat on using window.open() is that if the url that you pass to it doesn't have http:// or https:// in front of it, angular treats it as a route.
To get around this, test if the url starts with http:// or https:// and append it if it doesn't.
let url: string = '';
if (!/^http[s]?:\/\//.test(this.urlToOpen)) {
url += 'http://';
}
url += this.urlToOpen;
window.open(url, '_blank');
// suffice? eg: window.open(``//${this.urlToOpen}``, '_blank')
in HTML:
<a class="main-item" (click)="onNavigate()">Go to URL</a>
OR
<button class="main-item" (click)="onNavigate()">Go to URL</button>
in TS file:
onNavigate(){
// your logic here.... like set the url
const url = 'https://www.google.com';
window.open(url, '_blank');
}
Another possible solution is:
const link = document.createElement('a');
link.target = '_blank';
link.href = 'https://www.google.es';
link.setAttribute('visibility', 'hidden');
link.click();
I want to share with you one more solution if you have absolute part in the URL
SharePoint solution with ${_spPageContextInfo.webAbsoluteUrl}
HTML:
<button (click)="onNavigate()">Google</button>
TypeScript:
onNavigate()
{
let link = `${_spPageContextInfo.webAbsoluteUrl}/SiteAssets/Pages/help.aspx#/help`;
window.open(link, "_blank");
}
and url will be opened in new tab.
you can do like this in your typescript code
onNavigate(){
var location="https://google.com",
}
In your html code add an anchor tag and pass that variable(location)
<a href="{{location}}" target="_blank">Redirect Location</a>
Suppose you have url like this www.google.com without http and you are not getting redirected to the given url then add http:// to the location like this
var location = 'http://'+ www.google.com
To solve this issue more globally, here is another way using a directive:
import { Directive, HostListener, ElementRef } from "@angular/core";
@Directive({
selector: "[hrefExternalUrl]"
})
export class HrefExternalUrlDirective {
constructor(elementRef: ElementRef) {}
@HostListener("click", ["$event"])
onClick(event: MouseEvent) {
event.preventDefault();
let url: string = (<any>event.currentTarget).getAttribute("href");
if (url && url.indexOf("http") === -1) {
url = `//${url}`;
}
window.open(url, "_blank");
}
}
then it's as simple as using it like this:
<a [href]="url" hrefExternalUrl> Link </a>
and don't forget to declare the directive in your module.
var url = "https://yourURL.com";
var win = window.open(url, '_blank');
win.opener = null;
win.focus();
This will resolve the issue, here you don't need to use DomSanitizer. Its work for me
we can use target = blank to open in new tab
<a href="https://www.google.co.in/" target="blank">click Here </a>

window.open()must be called within a callback which is triggered by a user action (example onclick).
