jquery - select class elements and add to array

Question

I want to select all the elements with the class "play" and add them into array "esArreglo".

html file:

<td id="b1" class></td>
<td id="b2" class></td>
<td id="b3" class="play"></td>
<td id="b4" class="play"></td>

code:

$('td.play').each(function() {
    notas.push(this.id)};

var esArreglo = notas.join(',');

How can I fix this? Thanks.

What is the problem? You code looks fine except for a stray missing ) at the end before your var esArreglo statement, ie }); right after the notas.push.... And move the ; to after the .push() part. — Jared Farrish

You could use jQuery.map

var esArreglo = $('td.play').map(function() {
  return this.id;
}).get().join(',');

$.fn.map(), which you're using in your answer, behaves a little differently than $.map(). It returns a jQuery object, not an array, so you have to call get() before join() for your code to work.

May coz be you are missing the ); in .each

$('td.play').each(function() {
    notas.push(this.id)
});

var esArreglo = notas.join(',');
