Javascript 如何使.getDay返回数字以外的内容？

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，只留下星期一的单词？

示例

返回工作日的名称（不仅仅是数字）：

n的结果将是：

Tuesday

嗯，我想你面临的问题是，你必须写多个if-else和check。您可以使用下面的函数一次性完成

function myFunction() {
  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()];
  alert(n);
}

希望这能有所帮助。

您可以通过放置一组工作日来尝试这一点

var Weekday_name = ['Monday', 'Tuesday', 'Wednesday' ...]
var dob = new Date("April 2,1984");
var weekDay = dob.getDay();
console.log(Weekday_names[weekDay]);

您可以使用删除行

document.write（工作日）
var Weekday_name = ['Monday', 'Tuesday', 'Wednesday' ...]
var dob = new Date("April 2,1984");
var weekDay = dob.getDay();
console.log(Weekday_names[weekDay]);
