parent method return duplicate elements

[blairmitchelmore]

When you have multiple elements from the same parent elements in a jQuery array and then call parent, the resultant jQuery array contains multiple references to the same element.

Test case found at  http://jquery.offput.ca/tests/parent.php

The page will alert '6' and it should alert '1'

I've fixed the bug (if it is a bug and not a "feature") but simply calling jQuery.unique inside the .parent() method.

                var ret = jQuery.map(this,n);
                if ( a && typeof a == "string" )
                        ret = jQuery.multiFilter(a,ret);
-               return this.pushStack( ret );
+               return this.pushStack( jQuery.unique(ret) );
        };
 });

I don't see any major consequences from this and it would be an easy patch for jQuery core. (Of course you could also patch pushStack to ensure things are unique, but that could be overkill.)
