Why can't I open a link without http or https using window.open() in Javascript?

December 30, 2022

I can click "Open 1" button to open a full link in a new tab in Chrome.

When I click "Open 2" button, I can’t open a the link without http or https, the browser URL address displays http://localhost:53484/www.google.com.

How can I fix it?

Code A

<html>
<head>
    <script src="Js/jquery-3.6.3.min.js"></script>

    <script type="text/javascript">

        function open1() {
            window.open('http://www.google.com')
        }

        function open2() {
            window.open('www.google.com')
        }
    </script>
</head>

<body>

    <input type=button value="Open 1" onclick="open1()">

    <input type=button value="Open 2" onclick="open2()">

</body>

</html>

>Solution :

http or https are needed to open an external link (i.e. to access any website in the world wide web) – it won’t ever work without this, this is the official protocol. So if you have a link without it, every browser will automatically add it.
