具体代码如下：
<!DOCTYPE html> <html> <head> <title>获取时间</title> <script type="text/javascript"> window.onload = function(){ showTime(); } function showTime(){ var myDate = new Date(); var year = myDate.getFullYear(); var month = myDate.getMonth() + 1; var date = myDate.getDate(); var dateArr = ["日","一",'二','三','四','五','六']; var day = myDate.getDay(); var hours = myDate.getHours(); var minutes = formatTime(myDate.getMinutes()); var seconds = formatTime(myDate.getSeconds()); var systemTime = document.getElementById("time"); systemTime.innerHTML = " " + year + "年" + month +"月" + date + "日" + " 星期" + dateArr[day] + " " + hours + ":" + minutes + ":" + seconds; setTimeout("showTime()",500); } //格式化时间：分秒。 function formatTime (i){ if(i < 10){ i = "0" + i; } return i; } </script> </head> <body> <div id ='time'></div> </body> </html>
