javascript arrays in array based on input values

Question

The following code produces an array based on values of the designated inputs:

 <input value="jan, feb, mar">
 <input value="apr, may, jun">
 <input value="jul, aug, mar">

  ####

  anArray = []
  $("input").each ->
      tv = $(this).val()
      anArray.push(tv)
  console.log anArray

  >>> ["jan, feb, mar", "apr, may, jun", "jul, aug, sep"]

How can I make it to be a set of arrays wrapped in another array?

[ ["jan, feb, mar"], ["apr, may, jun"], ["jul, aug, sep"] ]

I also somewhat managed it to do as a set of objects, but I don't need a key at all. Maybe I can strip this object of key, leaving only value?

    content = $("input")
    object = $.map content, (x) ->
        'key': $(x).val()
    console.log JSON.stringify(object)

    >>> [{"key":"jan, feb, mar"},{"key":"apr, may, jun"},{"key":"jul, aug, mar"}]

In the end I'm going to post this data via JSON to the server, so all what I really need is to meet controller expectations of the data format where each input's value will be grouped together and separated with coma.

@Quentin Why was this one closed? It is not a duplicate of the linked question. There is an easy solution to this question, but it has got nothing to do with separating a string into an array. Just doing `anArray.push([tv])` should do the trick. — altocumulus, Oct 19 '15 at 22:25

Instead of pushing the string, push an array with the strings:

anArray = []
$("input").each ->
    tv = $(this).val()
    anArray.push([tv])
console.log anArray

use the split function:

anArray = []
  $("input").each(function(tv){
      tv = $(this).val()
      anArray.push(tv.split(","))
  })
      
  document.write(JSON.stringify(anArray));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input value="jan, feb, mar">
<input value="apr, may, jun">
<input value="jul, aug, mar">

`document.write` is considered bad practice, use `console` Object to test. – Roko C. Buljan Oct 19 '15 at 22:30
