javascript - 如何使 .getDay 返回数字以外的内容？

Question

结果显示“Monday1”，因为.getDay方法将1显示为星期一。

var dob = new Date("April 2,1984");
var weekDay = dob.getDay();
if (weekDay==1) {
document.write('Monday');
}
document.write(weekDay);

有没有办法去掉这个号码，只留下星期一的字？

Answer 1

示例

返回工作日的名称(不仅仅是数字):

var d = new Date();
var weekday = new Array(7);
weekday[0] =  "Sunday";
weekday[1] = "Monday";
weekday[2] = "Tuesday";
weekday[3] = "Wednesday";
weekday[4] = "Thursday";
weekday[5] = "Friday";
weekday[6] = "Saturday";

var n = weekday[d.getDay()];

n 的结果将是:

Tuesday
