Display day of the week with Javascript date
提问by user1522879
I am using the code below to display a date 7 days in the future. However this javascript code formats the date by mm/dd/yyyy.
我正在使用下面的代码显示未来 7 天的日期。但是，此 javascript 代码按 mm/dd/yyyy 格式化日期。
I would like to modify the javascript code below to have it display the day of the week instead such as Friday, Nov 1
我想修改下面的 javascript 代码，让它显示一周中的某一天，例如星期五，11 月 1 日
I do not need it to display the year.

Any help would be much appreciated as I am stumped.
任何帮助将不胜感激，因为我很难过。
<script>
var myDate=new Date();
myDate.setDate(myDate.getDate()+7);
var n=myDate.toLocaleDateString();
document.write(n);
</script>

try this , adding 1 week from current day output you get is :Friday,November 1
试试这个，从你得到的当天输出增加 1 周是：星期五，11 月 1 日
<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>

Datehas a getDay()method which returns a day number, starting with Sunday on 0 and continuing with Monday=1, Tuesday=2 and so on.
Date有一个getDay()返回天数的方法，从星期日 0 开始，继续星期一 = 1，星期二 = 2，依此类推。
You can use that to return just the week day. See How to get the day from a particular date using JavaScriptand similar questions.
您可以使用它来仅返回工作日。请参阅如何使用 JavaScript和类似问题从特定日期获取日期。
document.write(["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"][myDate.getDay()]);
