Need some help using Request.JSONP with the Flickr API. I haven't
been able to get a JSONP request to work without including the
"jsoncallback" parameter. This is not a required parameter in the API
url string and there is even a parameter to NOT have a JSON call
back ("nojsoncallback=1"), however this isn't working for me either
even though I follow the [url=http://www.flickr.com/services/api/
response.json.html]documentation[/url]. I don't want to have to
define a call back function as I can't pass any kind of parameters to
it. I want to handle everything in the onComplete handler of the
Request. Below are 3 examples of various code setups as well as the
associated firebug console output for each. Anyone with some Flickr
API experience, or just any possible idea, I would greatly appreciate
some advice.
Ex: 1 - Successful in that it calls the assigned function in the
"jsoncallback" attribute and the proper data is alerted, however the
onComplete handler never fires.
function infoHandler( data ) {
alert( data.photo.description._content );
}
var setRequest = new Request.JSONP({
url: 'http://api.flickr.com/services/rest/',
data: {
method: 'flickr.photos.getInfo',
api_key: //api key goes here,
photo_id: '3647421828',
format: 'json',
jsoncallback: 'infoHandler'
},
onComplete: function( data ) {
alert( 'requet complete' );
}
}).send();
Ex: 1 Console Output
["JSONP retrieving script with url:
http://api.flickr.com/services/rest/?callback=Request.JSONP.request_map.request_0&method=flickr.photos.getInfo&api_key=api_key_here&photo_id=3647421828&format=json&jsoncallback=infoHandler";]
Ex 2: - Passing the "nojsoncallback" parameter. JSON Output looks
fine to me but fails due to a "invalid label". Not sure what that
means. Again, onComplete handler never fires.
var setRequest = new Request.JSONP({
url: 'http://api.flickr.com/services/rest/',
data: {
method: 'flickr.photos.getInfo',
api_key: //api key goes here,
photo_id: '3647421828',
format: 'json',
nojsoncallback: '1'
},
onComplete: function( data ) {
alert( 'requet complete' );
}
}).send();
Ex: 2 Console Output
["JSONP retrieving script with url:
http://api.flickr.com/services/rest/?callback=Request.JSONP.request_map.request_0&method=flickr.photos.getInfo&api_key=api_key_here&photo_id=3647421828&format=json&nojsoncallback=1";]
invalid label
{"photo":{"id":"3647421828", "secret":"9...:{"nsid":"8317...@n05",
"username":"frac
Ex: 3 - Does not include a "jsoncallback" or "nojsoncallback"
parameter at all. Fails due to JSONFlickrAPI not being defined.
Again, onComplete handler never fires.
