javascript - 在页面打印年、月、日、星期，求教这段代码为什么不work？

Answer 1

首先你得确认你这段代码执行了没。这句写的不对，

var dy = new Array["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];

把new Array去掉。

var dy = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];

Answer 2

var dy = new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");

Answer 3

去掉 new Array, 直接

  var dy = []

Answer 4

var date = new Date();
var day = ['日','一','二','三','四','五','六'];
var strArr = [
    date.getFullYear()+'年', 
    (date.getMonth()+101+'').substring(1)+'月',
    (date.getDate()+100+'').substring(1)+'日'
];
strArr.join('') + ' 星期' + day[date.getDay()];

//2016年06月01日 星期三
