Detect the Enter key in a text input field

Question

I\'m trying to do a function if enter is pressed while on specific input.

What I\'m I doing wrong?

$(document).keyup(function (e) {
    if ($(\".inpu         


        

Answer 1

$(document).keyup(function (e) {
    if ($(".input1:focus") && (e.keyCode === 13)) {
       alert('ya!')
    }
 });

Or just bind to the input itself

$('.input1').keyup(function (e) {
    if (e.keyCode === 13) {
       alert('ya!')
    }
  });

To figure out which keyCode you need, use the website http://keycode.info
