Answer 1

I hope this simple jquery can help

html

<textarea></textarea>
<span id="adf" style="display:none; color:red">No space allowed and use comma to seperate</span>

Jquery

$('textarea').keypress(function(e) {
    if (e.which === 32) {
        $('#adf').css("display", "block");
        return false;
    }
    setTimeout(function() {
        $('#adf').slideUp('slow');
    }, 5000);
});
