How can I hide specific javascript file for mobile devices?

Question

How can I hide a specific javascript file for mobile devices? I use this code, but this code does not work for me.

<script type="text/javascript">
var ismobile = (/iphone|ipad|ipod|android|blackberry|mini|windows\sce|palm/i.test(navigator.userAgent.toLowerCase()));

if(!ismobile) document.write("<script src='http://source.com/script.js'> </script>");
</script>

What does "does not work" mean? Do you get errors? Have you tested the regex outside of this code? — Zim84, Aug 09 '18 at 05:09
I don't get any errors, but it does not work. It displays the symbols "); — s.balasundaram. inuson, Aug 09 '18 at 05:29

Try appending the script as an element instead of writing to the document

<script type="text/javascript">
    var ismobile = (/iphone|ipad|ipod|android|blackberry|mini|windows\sce|palm/i.test(navigator.userAgent));

    if (!ismobile){
        var script = document.createElement('script');
        script.src = 'test.js'; // or full url
        document.body.appendChild(script);
    } 

</script>
