Answer 1

Here is the code you need:

$(document).ready(function(){
  //for all
  $('.all').click(function(){
    $('input.sell').each(function() {
      var value = $(this).data('max');
      $(this).val(value);
    });
  });
  // and for each
  $('button.get').click(function() {
    var $parent = $(this).parent().parent();
    var $input  = $parent.find('input:first');
    var value = $input.data('max');
    $input.val(value);
  });
});
