How can I implement a time counter along with the character count codes.?
推荐答案var timeStart; var timeStop; $(document).load(function() { timeStart = new Date(); }); $('#form_3').on('submit', function() { timeStop = Math.round((timeStart.getTime() - Date().getTime()) / 1000); console.debug('time taken from load till submit: ' + timeStop); });
