110 enabling an Ajax search
handle the response
The PHP page sends back XML data, which must be handled by the JavaScript.
Add this new function to the search.js JavaScript fi le. (See extra bits on
page 126.)
1 This JavaScript function is called
when the ajax object??™s readyState
value changes (see the init() function).
The function receives the ajax
object when called.

anything until readyState has
a value of 4, meaning that the
Ajax transaction is complete.

to either 200 or 304, everything
worked fi ne and we can
use the returned results.
function handleResponse(ajax) {
if (ajax.readyState == 4) {
if ((ajax.status == 200) || (ajax.status == 304) )
{
