Read a DataSet object in Javascript

Hello

How exactly can I read the records of my DataTable in the DataSet that was sent as a response value from an Ajaxed Web Service?


function mapPostalCode(e)
{
      var postcode = $get("<%= txtPostcode.ClientID %>");
      var length = postcode.value.length;

      if (length == 4)
             MapPostalCode. Go to the complete details ...
