    I don't believe you.

    See the following Javascript line in your HTML:

    var emailReg = /^(?!.*_)\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})/;

    Again, follow the steps in my original post.

        Yes. Once you use single quotes, you don't need to put backslashes into your Javascript anymore. You can remove one backslash from each escape, turning \\w back into \w, and removing most of the others.

        Again, consider moving your HTML into external files.
