i can disable button when it's been clicked, how can enable when file has been downloaded. thank's in advance.

i believe should trigger window load event can bind handler enable button it, that

$(document).load(function(){    $('#buttonid').prop("disabled", false); });

please note didn't had chance test scenario , might require make tweaks before works.

hope helps!
