偶实现的代码
<!DOCTYPE html> <html lang="zh-cn"> <head> <meta charset="UTF-8"> <title>最少的代码实现当前的星期加时间</title> </head> <script type="text/javascript" src="jquery-1.10.1.min.js"></script> <h3 style=" text-align: center; padding-top: 6px;" id="weektime"></h3> <script type="text/javascript"> $(function() { weekTime(); }); //最少的代码实现当前的星期加时间,如果时间是个位数的前面补零 function weekTime(){ var now = new Date(); var today = new Array('星期日','星期一','星期二','星期三','星期四','星期五','星期六'); var week = today[now.getDay()]; var hh = now.getHours(), mm = now.getMinutes(), ss = now.getSeconds(); function zerofill(obj) { return obj < 10 ? '0' + obj : obj;} $('#weektime').text(week+' '+ zerofill(hh) + ':' + zerofill(mm) + ':' + zerofill(ss)); } </script> </body> </html>
结果群友(凌烟)实现更短的代码:
function weekTime(){ var now = new Date(); var week = '星期' + ['日','一','二','三','四','五','六'][now.getDay()]; var hh = now.getHours(), mm = now.getMinutes(), ss = now.getSeconds(); function zerofill(obj) { return obj < 10 ? '0' + obj : obj;} $('#weektime').text(week+' '+ zerofill(hh) + ':' + zerofill(mm) + ':' + zerofill(ss)); }
结果群友(hi)实现更短的代码:
function weekTime(){ var now = new Date(); //var week = now.toLocaleDateString("zh-cn", {weekday:'long'}); var week = '星期' + '日一二三四五六'.charAt(now.getDay()); var hh = now.getHours(), mm = now.getMinutes(), ss = now.getSeconds(); function zerofill(obj) { return obj < 10 ? '0' + obj : obj;} $('#weektime').text(week+' '+ zerofill(hh) + ':' + zerofill(mm) + ':' + zerofill(ss)); }
