Opening a link via javascript code

Question

I have a simple HTML/javascript question. I have a button and a link. My HTML looks like this :

<a id="a1" href="https://www.facebook.com/"> </a>
<input type="button">

How can I open the link by clicking the button? I know I can just type a function in javascript like

function f1() {
    location = document.getElementById("a1").href;
}

and put it in the onclick attribute of the button but I want the link to be opened in a new tab. Can anyone tell me how to do this via javaScript/HTML?

Answer 1

You can try with window.open:

function f1() {
    window.open(document.getElementById("a1").href, "_blank");
}
