星期几周

Question

我是一个javascript新手。我正在学习，我正在努力获得星期几，并将其写入文档。我正在使用阵列和开关盒。

检查我的代码：

var currentDate=new Date();
var currentDay=currentDate.getDay();
var daysOfWeek=["Sunday","Monday","Tuesday","Wed","Thu","Fri","Sat"];

switch(currentDay){
    case 0:
    document.write('Today is  <b>' +daysOfWeek[0]);

    break;
    case 1:

    break;
    case 2:

    break;
    case 3:

    break;
    case 4:

    break;
    case 5:

    break;

    case 6:

    break;
    default:
    break;
}

它工作正常，但我需要知道这是否是我能写的最好的代码，或者我是否可以改进它。

Answer 1

这样做的一个更好的方法（保持一般方法）将是：

var currentDate=new Date();
var currentDay=currentDate.getDay();
var daysOfWeek=["Sunday","Monday","Tuesday","Wed","Thu","Fri","Sat"]; 
document.write('Today is  <b>' +daysOfWeek[currentDay] + '</b>');
