Answer 2

您可以像这样使用子字符串。 https://jsfiddle.net/7yq6zxLk/

  var n = 20160509125119040;
  var formatDate = n.substring(0,4) + "-" + n.substring(4,6) + "-" + n.substring(6,8) + " " + n.substring(8,10) + ":" + n.substring(10, 12) + ":" + n.substring(12, 14);

Answer 3

试试这个：

var dd ="20160509125119040";
var year = dd.substring(0, 4); var month = dd.substring(4).substring(0, 2); var date = dd.substring(6).substring(0, 2)
var hour = dd.substring(8).substring(0, 2); var min = dd.substring(10).substring(0, 2); var sec = dd.substring(12).substring(0, 2)
var finaldate = year+"-"+month+"-"+date+" "+hour+":"+min+":"+ sec;
alert(finaldate)
