  2. Alphanumeric, dash and underscore but no spaces regular expression check Javascript


    var regexp = /^[a-zA-Z0-9-_]+$/;
    var check = "checkme";
    if (check.search(regexp) == -1)
        { alert('invalid'); }
    else
        { alert('valid'); }

    var check = "checkme";
    if (check.search(regexp) == -1)
        { alert('invalid'); }
