如何从特定日期开始使用JavaScript [英] How to get the day from a particular date using JavaScript

问题描述

我刚开始使用JavaScript。我的要求是，要在特定日期（例如星期日，星期一...）弹出一条消息，通过选择日期。

我试过 getday（）函数，但它没有工作。
请建议如何做。

解决方案

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

day 现在拥有一个从零到六;零是星期天，一个是星期一，等等。

所以剩下的只是将该号码翻译成英文（或任何其他语言）的日期名称字符串：

  var name = [星期日，星期一，星期二，星期三星期五，星期六] [天] 
  

I am new to JavaScript. My requirement is that T want to pop up a message on particular days (like Sunday, Monday...) all through when a date is selected.

I tried getday() function but it didn't work. Please suggest how to do this.

解决方案

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

day now holds a number from zero to six; zero is Sunday, one is Monday, and so on.

So all that remains is to translate that number into the English (or whatever other language) string for the day name:

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