.promise() does not attach methods onto target

Reported by: fastfasterfastest Owned by: gibson042
Priority: high Milestone: 1.7.2
Component: queue Version: 1.7.1

Blocked by: Blocking:

Documentation for .promise() ( states "If target is provided, .promise() will attach the methods onto it and then return this object rather than create a new one."

This is not what is happening in 1.7.1.

I am not sure what a good use-case for this is, but the following demonstrates the issue:

var foo = {};

$(document.body).promise("foo", foo);

If 1.7.1. did what the documentation states then "hello" would be alerted. Instead, there is a javascript error.

Looking at the sources, one can also see that the parameter named 'object' is never used in .promise().

I believe it is either an implementation bug, or a documentation bug.

(Note, this is a report about .promise() (documented at, not about deferred.promise() (documented at

Confirmed. jQuery.fn.promise should be returning defer.promise( object ) instead of defer.promise()
