Listdata.svc and $expand

Question

Normally I would use jQuery to get data from listdata.svc like this:

$.getJSON(listUrl,
            function (data) {
                $.each(data.d.results,
                function (i, result) {

A little clarification. This is my data source:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<feed xml:base="http://contoso/_vti_bin/listdata.svc/">

</feed>

I need the titles from the m:inline > feed > entry > title ...

Update: Using console.log(JSON.stringify(data.d.results)) yields this object:

LOG: [{
"__metadata":{...},
"ContentTypeId":"0x0100A9CFFA37DE22C641B71785403A8E5571",
"Title":"This title is what i get with data.d.results[i].Title",
"Unit":{"__deferred":{"uri":"..."}},
"UnitId":8,
"Subunits":{
"results":[{
  "__metadata":{...},
  "ContentTypeId":"0x01009D2BABDBD41F8543A022ECD6225898E4",
  "Title":"This title is what I need",
  "Path":"..."},
  {"__metadata":{...},
  "ContentTypeId":"0x01009D2BABDBD41F8543A022ECD6225898E4",
  "Title":"And this one",
  ...

Answer 1

The title should be in result.Title inside your function.

data.d.results[].Title

You can do a console.log(result) in the function in order to print all of the objects out to the console (F12 or Ctrl+Shift+K in Firefox) so you can browse the values.

When working with JS you can do some fiddling around in the console to help expedite the development in this way.

Answer 2

Given your results, and the title you identified, the first title would be:

data.d.results[0].Subunits.results[0].Title
