I am trying to create an array of object that will have multiple children. I have a table with data like this:

```
| PARENT   | CHILD  |
---------------------
| 123456   | 123    |
| 123456   | 124    |
| 123456   | 125    |
| 123457   | 345    |
| 123457   | 346    |
| 123457   | 347    |
....

```

I wish to get an array similar to this:

`var arr_nos = { 123456 : [123, 124, 125], 123457 : [345, 346, 347]}`

During a loop, I have this:

```
var arr_nos = [];
$('#table tbody tr').each(function( index ) {
   var parent_no = elem.find('.parent_no').html();
   var child_id = elem.find('.child_id ').html();
   if(parent_no != '') {
      child = [
         child_id
      ]
      arr_nos.push(parent_no, child);
   }

});

```

But this results in:

```
["123456", Array(1), "123456", Array(1),"123456", Array(1), "123457", Array(1), "123457", Array(1), "123457", Array(1)]

```
