Multi-Try $.promise
This method wraps a provided callback that returns a jQuery promise (or jqXHR object) and allows that asynchronous functionality to fail and be retried without rejecting the returned promise.
multiTryPromise = (callback, numberOfTries, evaluate, options) ->
deferred = $.Deferred()
retry = =>
if deferred.state() is 'pending' and
numberOfTries and
(not evaluate? or evaluate arguments)
numberOfTries--
callback(options).then deferred.resolve, retry
else
deferred.rejectWith @, arguments
numberOfTries--
callback(options).then deferred.resolve, retry
deferred.promise()
