defer (label) Objectstatic
RSVP.defer returns an object similar to jQuery's $.Deferred. RSVP.defer should be used when porting over code reliant on $.Deferred's interface. New code should use the RSVP.Promise constructor instead.
The object returned from RSVP.defer is a plain object with three properties:
- promise - an
RSVP.Promise. - reject - a function that causes the
promiseproperty on this object to become rejected - resolve - a function that causes the
promiseproperty on this object to become fulfilled.
Example:
1 2 3 4 5 6 7 | var deferred = RSVP.defer();deferred.resolve("Success!");deferred.promise.then(function(value){ // value here is "Success!"}); |
Parameters:
-
label
String - optional string for labeling the promise. Useful for tooling.
