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

EN

// 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);
  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>

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>
