（如有错敬请指点，以下是我工作中遇到并且解决的问题）

效果有两种：

两者区别是

1.第一天（今天）显示今日

代码中改变showToday的值即可

JAVASCRIPT:

var showToday = false // 今天显示“周几”还是显示“今日”document.getElementById('today').innerText = GetDateStr(0)

document.getElementById('fourthday').innerText = GetDateStr(3)
document.getElementById('fifthday').innerText = GetDateStr(4)
document.getElementById('sixthday').innerText = GetDateStr(5)
document.getElementById('seventhday').innerText = GetDateStr(6)function GetDateStr(Count) {
var dd = new Date()
dd.setDate(dd.getDate() + Count) //获取Count天后的日期
var m = dd.getMonth() + 1 //获取当前月份
m = m < 10 ? '0' + m : m
var d = dd.getDate() //获取当前月份的日期
d = d < 10 ? '0' + d : d
var w = dd.getDay() //获取星期几
var week
switch (w) {
case 0:
week = '周日'

return m + '/' + d + week
}
