Altering existing javascript (onKeyup script)

I have an existing javascript code which simply transposes what someone types in a textbox into a <span> area on the page.

At the moment the <span> preview text is in brackets (as shown in the code below).  

Can someone tell me what the correct syntax for the code below so that the brackets are not shown around the outputted text?  (it's a simple question i know!).
function previewer()
{
        var subMenu = document.getElementById('preview');
        var inputtext = document.forms[0].companyname.value;
        subMenu.innerHTML = "(" + inputtext + ")"; 
        
}
