如何在JavaScript购物中为date对象创建11天后的JavaScript代码

Question

我想把日期注入到shopify description产品的html中

它会说

我们将从今天起+ 11天内发货.

如果是星期六或者星期天的话就会移到星期一，因为星期六或者星期天是休息日。

代码现在是这样的，但是如果需要的话，不知道如何把它移到第一个星期一

​

// get the destination within the DOM
var wrapper = document.getElementById('productEta'),

  // get today as a js Date object
  today = new Date(),

  // get the Unix of today (miliseconds) and add desired time (3 weeks)
  etaUnix = today.getTime() + (60 * 60 * 24 * 11 * 1000),

  // convert the new time to date object and then to a human readable string
  etaForHumans = new Date(etaUnix).toDateString();

// set the destination inner html to be what it already is
// plus a space and the human readable string.
wrapper.innerHTML += ' ' + etaForHumans;

<div id="productEta">Product will arrive by: </div>

但是脚本也有问题

  etaForHumans = new Date(etaUnix);
  var day = etaForHumans.getDay()
  if(day==0)
      etaForHumans.setDate(etaForHumans.getDate() + 1);
  if(day==6)
      etaForHumans.setDate(etaForHumans.getDate() + 2);

// set the destination inner html to be what it already is
// plus a space and the human readable string.
wrapper.innerHTML += ' ' + etaForHumans+ ' ' + day;

<div id="productEta">Product will arrive by: </div>

Answer 2

​

var wrapper = document.getElementById('productEta');
var today = new Date(Date.parse('2019-03-05'));
var etaDate = new Date(today.getTime() + (60 * 60 * 24 * 11 * 1000))
while(etaDate.getDay() == 0 || etaDate.getDay() == 6){
	//Add one day until it is not saturday or sunday
	etaDate.setTime(etaDate.getTime() + (60 * 60 * 24 * 1000));
}

var etaForHumans = etaDate.toDateString();
// set the destination inner html to be what it already is
// plus a space and the human readable string.
wrapper.innerHTML += ' ' + etaForHumans;

<div id="productEta">Product will arrive by: </div>

Answer 3

momentJS。看看这个。允许你以一种理智的方式处理日期。有用于请求nextBusinessDay()和更多内容的插件。

不要摆弄日期和普通的Javascript，除非你是一个高手Javascript程序员。它很糟糕，momentJS的存在是有充分理由的。更少的差劲。
