Class TimeMap.loaders.jsonp

Extends:: TimeMap.loaders.remote
Defined in:: json.js

JSONP loader - expects a service that takes a callback function name as the last URL parameter.

The jsonp loader assumes that the JSON can be loaded from a url to which a callback function name can be appended, e.g. "http://www.test.com/getsomejson.php?callback=" The loader then appends a nonce function name which the JSON should include. This works for services like Google Spreadsheets, etc., and accepts remote URLs.
