Answer 1

Well firstly, insert a:

return false;

at the end of your insertData() function, in that way you prevent the refresh of the page so that the ajax call can load its data.

Second you are returning Success and you are trying to read success, it's case sensitive and your code will not reach that if.

Resolve these issues and get back to me

Answer 2

Make a PHP script (lets name it getvalues.php) to return the values from the database into JSON, such as:

$result = mysql_query("SELECT * FROM $you_table"); //mod query to match what you need to fetch
$array = mysql_fetch_row($result);   
echo json_encode($array);

Then in your script above include jQuery and use something along the lines of the following to retrieve the data:

$(function () 
  {
    $.ajax({                                      
      url: 'getvalues.php',         
      data: "",                        
      dataType: 'json',  
      success: function ( values )
      {
        var value1 = values[0]; //value1, value2, etc should represent the field names in your database
        var value2 = values[1];
        //and so on and so forth. each field in you DB should be one index in your values array
        $('#output').html("<b>Value 1: </b>"+value1+"<b> Value 2: </b>"+value2); 
      } 
    });
  });
