I'm trying to hide an element based on its ID, but, I haven't been able to get it to work. I've Googled the answer but, no matter what I do, I can't seem to get it to work for me.

My code is attached below.

<!DOCTYPE html>
<html>
    <!-- HTML -->
    <body>

            <button> Edit </button>
        </div>
    </body>

    <!-- Javascript -->
    <script>
        if(document.getElementById("role").value == 'Edit'){
            document.getElementById("role").style.display = 'none';
        }
    </script>
</html>

You can use querySelector instead of getElementById if you want.

var role = document.querySelector('#role');

if(role.getAttribute('value') == 'Edit'){
    role.style.display = 'none';
}
<!DOCTYPE html>
<html>

    <body>
        <div id="role" value="Edit">
            <button> Edit </button>
        </div>
    </body>
</html>
