API

jsonp(url, opts, fn)

• url (String) url to fetch
• opts (Object), optional
  • param (String) name of the query string parameter to specify the callback (defaults to callback)
  • timeout (Number) how long after a timeout error is emitted. 0 to disable (defaults to 60000)
  • prefix (String) prefix for the global callback functions that handle jsonp responses (defaults to __jp)
  • name (String) name of the global callback functions that handle jsonp responses (defaults to prefix + incremented counter)
• fn callback

The callback is called with err, data parameters.

If it times out, the err will be an Error object whose message is Timeout.

Returns a function that, when called, will cancel the in-progress jsonp request (fn won't be called).
