提前阅读日期

Question

我想知道是否可以将下面的日期修改为提前2周阅读，而不是阅读实际日期？

<script language="JavaScript">
  var now = new Date();
  var dayNames = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
  var monNames = new Array("January","February","March","April","May","June","July","August","September","October","November","December");
  document.write(" " + dayNames[now.getDay()] + " " + monNames[now.getMonth()] + " " + now.getDate() + ", " + now.getFullYear());
</script>
				
<!--End Date Script-->

Answer 1

var daysToAdd = 14; 
var myDate = new Date(new Date().getTime()+(daysToAdd * 24 * 60 * 60 *1000));

var output = [
  dayNames[myDate.getDay()],
  monNames[myDate.getMonth()],
  myDate.getDate(),
].join(' ') + ', ' + myDate.getFullYear(); // "Thursday April 23, 2015"
