Jim, could you post a version of the XML data you'd expect?

Hi, I'm trying to change a bunch of handwritten Ajax stuff to use jQuery's
methods. (I figure, if I'm already including the jquery.js file, I may as
well use the heck out of it.)
My current code sends a request to a php page and gets back an xml result
I do the standard way of creating a request object(try/catch for MSXML vs
XHR)
here is the code to create my request and callback:
var http = createRequestObject(); //this just references that object I
just created.
function ajax ( url, callback )
{
http.open ( 'get', url, true );
http.onreadystatechange = callback;
http.send(null);
}
function sendRequest() {
var url = "getItems.php?cat_id=" + idsource;
ajax( url, handleInfo );
}
my handleInfo function does a nice for loop based on an array(object) and
generates table html for each "record":
function handleInfo() {
if (http.readyState == 1) {
//document.getElementById("itemtable" +idsource).innerHTML
= '<h1>Loading...</h1>'
}
if (http.readyState == 4) {
if (http.status == 200) {
var xmlDoc =
http.responseXML.documentElement;
var output;
output = '<table><thead><tr><th>Items
Available</th></tr></thead><tbody>';
// Create table rows for each record
for (var i=0; i < xmlDoc.childNodes.length;
i++)
{
var linkId =
xmlDoc.getElementsByTagName('item_id').item(i).firstChild.data;
output += '<tr>';
output += '<td>'+linkId;
output += '<td><a href="
itemdetail.php?item_id='+linkId+'"
>'+xmlDoc.getElementsByTagName('item_name').item(i).firstChild.data+'</a></td>';
output += '</tr>';
}
output += '</tbody></table>';
document.getElementById("itemtable"
+idsource).innerHTML = output;
}
}
}
Ok, fairly generic routine stuff. Only problem is, I can't bend my mind
around the way to do it in jQuery!!! I have started playing around with the
.get method:
$(document).ready(function() {
$('#resultcontainer').accordion();
$("dt").click(function(){
idsource = $(this).attr("id");
$.get("getItems.php", {cat_id:
idsource}, function(xml){
//build a table from xml
results.
var output =
'<table><thead><tr><th>Items Available</th></tr></thead><tbody>';
var xmlDoc =
xml.documentElement;
//create rows for each
result.
for (var i=0; i<
xmlDoc.childNodes.length; i++)
{
var linkId =
$("item_id", xmlDoc).item(i).firstChild.data;
output += '<tr>';
output +=
'<td>'+linkId+'</td>';
output += '</tr>';
}
output +=
'</tbody></table>';
$('#itemtable'+idsource).html(output);
});
})
});
but this seems to cough up errors about linkId not being a function.....
Am I at least on the right path?
What this code does is everytime one clicks on a "dt" element, it sends
the request based on the id.... (just a number) then it submits the ajax
request. I'm really not sure at all how to deal with the object it
returns... so that's why you see me treating it just like I would any other
xml object.
I'd be happy to post all my code but I don't want to suck up a ton of
bandwidth... this being my first post and all that.....
(In a future revision of this code, I'll actually let the accordian wait
until the object is returned before I slide it down.....)
Thanks,
-Jim
