為什么星期出不來
//通過javascript的日期對象來得到當前的日期，并輸出。
? var mydate =new Date();
? var weekday = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];
??
? document.write(
? ? ? mydate.getFullYear() + "年" +( mydate.getMonth()+1 )+ "月" + mydate.getDate() + "日" + "" + weekday[mydate.getDate()] +"<br/>");
??
2017-01-15
var myday=mydate.getDay();
document.write(weekday[myday])
應該是少了獲取星期的變量
