Answer 1

var formStr = $('#container').serialize()

Added: That will work for form elements. You could also roll your own serialize like so:

function serializeList(container)
{
  var str = ''
  var n = 0
  var els = container.find('li')
  for (var i = 0; i < els.length; ++i) {
    var el = els[i]
    var p = el.id.lastIndexOf('_')
    if (p != -1) {
      if (str != '') str = str + '&'
      str = str + el.id.substring(0, p) + '[]=' + (n + 1)
      ++n
    }
  }
  return str
}

alert(serializeList($('#container')))
