$ ("div"). Text (Arr.join (","));arr = Jquery.map (arr, function (n, i) {
Return (N.touppercase () + i);
});
$ ("P"). Text (Arr.join (","));arr = Jquery.map (arr, function (a) {return a + A;});
$ ("span"). Text (Arr.join (","));</script>

jquery.fn.joinattr = function (sep,attr) {
Return This.join (Sep,function (item) {return $ (item). attr (attr);});
};
Jquery.fn.joinvalue = function (Sep) {
Return This.join (Sep,function (item) {return $ (item). val ();});
