I’m working on reply function using mysql and php.

My MySQL db:

reply:
  rid - id;
  topicid - under which topic;
  uid - id of the guy who replies;
  content - what did the guy said.

Here’s my html code:

<form id="replyform">
  <textarea name="rplcont" placeholder="Press enter to submit your reply."><textarea>
</form>

My question is: How do I know if enter button is pressed?

Many thanks.

here’s my codes that work:

html:

<textarea id="reply" name="reply" onKeyPress="enterpressalert(event, this)"></textarea>

js:

function enterpressalert(e, textarea){
var code = (e.keyCode ? e.keyCode : e.which);
if(code == 13) { //Enter keycode
 alert('enter press');
}
}

and it works.

Thanks for everyone who concerns this topic!
