I was reading a lot of examples in order to execute a simple JSON query from yahoo
place finder api but I still can't get anything that works.

I had success with making it work with a simple php format but I don't want my page to refresh so now I must try and do this in ajax.

putting it simple: I need to retrieve data from:


(not for the general case but enough for me understanding how to do it)

which is in the JSON format and parse the "uzip" field (any field would do for me to understand).

please help me with the lines I'm searching for- couldn't find the exact thing- thanks a lot.

You need to use JSONP and not a basic ajax call :

Using jQuery it's faster :
$.getJSON("http://where.yahooapis.com/geocode?location=San+Francisco,+CA&flags=J&appid=yourappid", function(data) {
     // parse the data now

Open in new window

Else with simple javascript (note the parameter callback at the end of your URL) :

var cb = function(data) {
// parse the data now

var script = document.createElement('script');
script.src = "http://where.yahooapis.com/geocode?location=San+Francisco,+CA&flags=J&appid=yourappid&callback=cb";

Open in new window

If you need more help, don't hesitate.

i tried using the callback but it wouldn'y work.
if you try the link as you put it with the callback=cb you'll see
that yahoo don't had the cb(...) around the respond as expected

ok, the fastest workaround is to use a proxy.

$.getJSON("path/to/proxy.php?url=" + encodeURIComponent("http://where.yahooapis.com/geocode?location=San+Francisco,+CA&flags=J&appid=yourappid"), function(data) {
     // parse the data now

with the following php proxy (light) :
   echo file_get_contents($_GET['url']);

Open in new window
