如何让.getDay返回数字以外的内容？

Question

结果显示“Monday1”，因为.getDay方法显示1为星期一。

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

有什么办法摆脱这个号码，只留下星期一的字？

Answer 1

例

返回星期几的名称（不只是一个数字）：

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

嗯，我猜问题y你面对的是，你将不得不写多个如果其他和检查。你可以使用下面的功能来完成它一劳永逸的

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); 
} 

希望这会有所帮助。

你可以把平日的数组

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