How to Submit textarea comment on Enter key?

[eluser]Volkof[/eluser]
I understand the feedback of not recommending this method, but because facebook does this and my team members asked me to follow, so I had to do it.

So far I continued my search and pieced the info together with the code you guys have given me, and I got this:

Code:

function checkSubmit(e)
{
   if(e && e.keyCode == 13)
   {
      event.preventDefault();
        alert("Submit!");

        $("#commentForm").submit();
   }
}

I retained the onKeyPress in the textarea. The alert window did pop out.

Now the problem is I'm not sure how to pass the data from javascript to the Controller.
Basically I need 2 parameters (comment & reviewID) to be passed. My controller looks like this:

Code:

public function addComment()
{
  $comment = trim($this->input->post('comment'));
  $reviewID = $this->input->post('reviewID');
  
  if($comment != ''){
   //Get UserID from Session
   $userID = $this->members();  
   echo '<br/>Commenter = '.$userID;
   $this->comment_model->addComment($comment, $userID, $reviewID);
   echo 'Comment added!';
  }else{
   echo 'You didnt comment anything :(';
  }
  
}

Help will be appreciated. Thank you
