Can the Date / String objects be used to get the day of the week from dayNumber?

推荐答案

这将给你一个基于您通过的索引的一天：

This will give you a day based on the index you pass:

var weekday=new Array(7);
weekday[0]="Monday";
weekday[1]="Tuesday";
weekday[2]="Wednesday";
weekday[3]="Thursday";
weekday[4]="Friday";
weekday[5]="Saturday";
weekday[6]="Sunday";
console.log("Today is " + weekday[3]);

输出今天是星期四

您可以通过 getDay（）（但是在这种方法中，星期日为0，星期一为1等）从JavaScript获取当前日期索引：

You can alse get the current days index from JavaScript with getDay() (however in this method, Sunday is 0, Monday is 1, etc.):

var d=new Date();
console.log(d.getDay());

星期一输出1。
