I assume you also want to keep hyphens since they represent where whitespace is in the article title. Here's an amended version of your function, the two regular expressions have been changed to better suit what you're looking for.

JavaScript Code:

function updatelink()
{
    var title = document.getElementById("articleTitle").value;

    // 1. Replace whitespace with hyphen character
    var clean = title.replace(/\s+/g, "-");
    // 2. Strip non-alpnanumeric-or-hyphen characters
    clean = clean.replace(/[^A-Z0-9-]/gi, "");

    var postlink = document.getElementById("postlink");
    postlink.firstChild.nodeValue = clean;
    
}
