with CSS or any other way, is it possible to disallow newlines in a HTML textarea? So basically I want nothing to happen when the user presses "enter".
Using jQuery, you could do it like this:
$(document).ready(function() {
$("#t_area").keypress(function(event) {
if(event.which == '13') {
return false;
}
});
});
<textarea id="t_area"></textarea>
I would also strip out any newlines using PHP or ASP or whatever server-side scripting language you have access to as well to be completely thorough.
its posible with wrap="soft,hard, or off
