• javascript
• jquery

• 1 With jquery, bind the keyup event of the textarea, capture the event object in the first argument. Use this object to cancel event when the pressed key is enter. I believe it s code is 13. jQuery has all the doc for that, SO all the posts for that also. One thing not to do is to cancel the propagation, otherwise you may need to also trigger submit event at that point. – user4466350 Commented Jun 27, 2015 at 4:28

Just listen to the keydown event and prevent the default action (which is the linebreak)

$("textarea").on("keydown", function(e) {
    if(e.which === 13) { // enter key
        e.preventDefault(); // prevents linebreak
        // here you could add your submit call
        return false;
    }
});

You can use jQuery to determine whether the textarea is active:

$("#foo").is(":focus") // expression is true only when it is active

So your code should look something like this:

if (<enter key pressed> and !($("#foo").is(":focus")))
  <submit with JavaScript and Ajax>
