  console.log("123");
});

<input type='text' id='textInput'/>

Answer 1

You have syntax error in you code. closing should be }); instead of )};

$("#textInput").keypress(function (e) {
     if(e.which == 13) {
        alert('You pressed enter!');
    }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="textInput">
