如何使用JavaScript从特定日期获取日期

Question

我是JavaScript的新手.我的要求是T想要在特定日期(如周日,周一......)弹出一条消息,直到选择日期为止.

我试过getday()功能,但它没有用.请建议如何做到这一点.

Answer 1

var date = new Date();
var day = date.getDay();

day现在持有从零到六的数字; 零是星期日,一个是星期一,依此类推.

所以剩下的就是将该数字转换为日期名称的英语(或其他任何语言)字符串:

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

Answer 2

var days= ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
var today = new Date();
document.write(days[today.getDay()]);
