var array = new Array();
        $('body').find(".postitons").each(function(index, element) {
            newArray = new Array();

            $(element).find('tr').each(function(index, tr) {
                values = new Array();
                $(tr).find('td').each(function(index, td) {
                    text = $(td).text();
                    values.push(text.trim());

                })

                newArray[$(tr).attr('id')] = values;
                array[$(element).attr('id')] = newArray;
            });

        });
    console.log(JSON.stringify(array);

array looks like this
