Question

我使用下面的代码显示将来7天的日期。但是，这个javascript代码将日期格式化为mm / dd / yyyy。

我想修改下面的javascript代码，让它显示星期几，例如星期五，11月1日

我不需要它来显示年份。

任何帮助都会非常感激，因为我很难过。

<script>
var myDate=new Date();
myDate.setDate(myDate.getDate()+7);
var n=myDate.toLocaleDateString();
document.write(n);
</script>

Answer 1

Date有一个getDay()方法，它返回一个日期编号，从星期日0开始，继续星期一= 1，星期二= 2，依此类推。

您可以使用它来返回工作日。请参阅How to get the day from a particular date using JavaScript和类似问题。

document.write(["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"][myDate.getDay()]);

Answer 2

试试这个，从当天输出的1周后你得到的是： 11月1日星期五

<script >
<!--

var m_names = ["January", "February", "March", 
"April", "May", "June", "July", "August", "September", 
"October", "November", "December"];

var d_names = ["Sunday","Monday", "Tuesday", "Wednesday", 
"Thursday", "Friday", "Saturday"];

var myDate = new Date();
myDate.setDate(myDate.getDate()+7);
var curr_date = myDate.getDate();
var curr_month = myDate.getMonth();
var curr_day  = myDate.getDay();
document.write(d_names[curr_day] + "," + m_names[curr_month] + " " +curr_date);

//-->
</script>

使用Javascript日期显示星期几
