You can filter out the bogus values of the original or create a new object and only set the valid values.
var data = $H(form.serialize(true)); var transportData = $H(); data.each(function(pair, itr) { if(pair[1] != "") transportData.set(pair[0], pair[1]); }); -- http://positionabsolute.net On Nov 8, 9:06 am, Braulio <brau...@solsoft.biz> wrote: > Hello. > > On 7 nov, 04:39, "T.J.
