Question

I have a textarea:

      <form id='test'>
      <textarea class='test2'> </textarea> <input type='submit' value='send'/>
      </form>

I would like to know if there is a way to limit the number of times a user can submit the textarea (for example, 5 times per minute).

EDIT:
I would like to do that on client-side, in Javascript.

EDIT 2:

It is for a chat. I just don’t want people to be able to post too many messages within a small lap of time. So it’s not a problem if they refresh their page to get ride of the limit, the time they’ll take to do it is long enough…

You can store some variables:

$(function () {
   var timesSubmitted = 0;
   var maxSubmits = 5;
   var intervalMilliseconds = 10000; // for testing   
   var interval;   
    $('input[type=submit]').click(function (event) {
        if (!interval) {
            interval = setTimeout(function () {
                interval = undefined;
                timesSubmitted = 0;
                $('div').append('TIMER RESET. Submit again.<br />')
            }, intervalMilliseconds);
        }
        timesSubmitted ++;
        if (timesSubmitted > maxSubmits) {
            $('div').append('NO GO YO!<br />')
        } else {
            $('div').append('valid<br />')   
        }
        event.preventDefault();        
    });        
});​
