Button that links to mulitple websites

Question

I'm trying to create a button that links to random websites like on 'The useless web'. I found this code on here and it's worked almost perfectly. I just need help making the sites open in a new tab, at the moment they change the current window. Any help will be greatly appreciated. THANKS

CURRENT:

<script type="text/javascript">
var urls = [
    "http://www.kittenwar.com/",
    'http://heeeeeeeey.com/',
    'http://cat-bounce.com/'
];

function goSomewhere() {
    var url = urls[Math.floor(Math.random()*urls.length)];
    window.location = url; // redirect
}

onClick handler assigned:

<a href="#" onClick="goSomewhere(); return false;">Gimme something weird!</a>

Answer 1

use this function

 function goSomewhere() {
        var url = urls[Math.floor(Math.random()*urls.length)];
        window.open(url, '_blank')
    }

Answer 2

To open a page in a new tab, you should create the button like this:

<button href='w3schools.com' target='_blank'>Click me!</button>

You can change the href tag with JavaScript.
