下面为大家附上代码，复制即可用：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>JS时间</title> <style> </style> </head> <body> <div id="time"></div> <script type="text/javascript"> function time(){ var vWeek,vWeek_s,vDay; vWeek = ["星期天","星期一","星期二","星期三","星期四","星期五","星期六"]; var date = new Date(); year = date.getFullYear(); month = date.getMonth() + 1; day = date.getDate(); hours = date.getHours(); minutes = date.getMinutes(); seconds = date.getSeconds(); vWeek_s = date.getDay(); document.getElementById("time").innerHTML = year + "年" + month + "月" + day + "日" + " " + hours + ":" + minutes +":" + seconds + " " + vWeek[vWeek_s] ; }; setInterval("time()",1000); </script> </body> </html>
