get value from json callback
Question
I am not trying to append flickr photos to my webpage. I am trying to retrieve the latitude and longitude values from the json call back.
This is the code I have so far. Nothing happens when I load it into my browser.
<!DOCTYPE html>
<html>
<head>
<title>Flickr Pie Chart</title>
<meta charset="utf-8">
<script type="text/javascript" src="/jquery/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#driver").click(function(event){
var apiKey = '[YOUR API KEY]';
var url = 'http://api.flickr.com/services/rest/&method=flickr.photos.search&api_key=' + apiKey +'&per_page=500&tags=losangeles&has_geo=1&extras=geo,tags&format=json&jsoncallback=?';
$.getJSON(url, function(data){
//loop through the results with the following function
$.each(data.items, function(i,item){
var geoData +='latitude:' item.latitude + '' + '<br>';
geoData += '' + item.longitude;
$('#results').append(geoData);
});
});
});
});
</script>
</head>
<body>
<div id = "results"></div>
<input type="button" id="driver" value="Load Data" />
</body>
</html>

This
http://api.flickr.com/services/rest/&method=flickr.photos.search&api_key=
Should be
http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=
But the respond you will get is
<rsp stat="fail"><err code="3" msg="Parameterless searches have been disabled. Please use flickr.photos.getRecent instead."/>
Which is telling you to use flickr.photos.getRecent

I got it working. One of the problems is that I had jsoncallback=? which was returning a jsonp file with a syntax error, it was not returning json. I found the error on the jsonlint.com website. The error had jsonFlickrApi({ at the beginning of the file. I added &nojsoncallback=1 after &format=json and everything worked fine. I also declared my geoData variable before assigning values.
Here is the code:
<!DOCTYPE html>
<html>
<head>
<title>Flickr Pie Chart</title>
<meta charset="utf-8">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script type="text/javascript">
var latitude;
var longitude;
var geoData;
$(document).ready(function(){
var apiKey = '[YOUR API KEY]';
var url = 'http://api.flickr.com/services/rest/?&method=flickr.photos.search&api_key='+ apiKey + '&tags=losangeles&has_geo=1&extras=geo,tags&format=json&nojsoncallback=1';
$.getJSON(url, function(data){
//loop through the results with the following function
$.each(data.photos.photo, function(i,item){
geoData += 'latitude' + ':' + item.latitude + '' + '<br>';
geoData += 'longitude' + ':' + item.longitude;
$('#results').append(geoData);
});
});
});
</script>
</head>
<body>
<div id = "results"></div>
</body>
</html>
