长整数到Javascript日期格式

Question

我有一个很长的整数值：20140307080000。这实际上是日期时间2014-03-07 08:00:00。 我已经在JS中尝试过Date.parse并将其转换为字符串，但是我无法将其作为Javascript日期对象来检索。 是否有任何JavaScript或D3内置方法将其转换为日期对象，而不是手动拆分？

Answer 1

// Your date String
var d = "20140307080000";

// Convert it to the format 2014-03-07 08:00:00
var f = d.replace(/(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/, "$1-$2-$3 $4:$5:$6");

// Alerting after parse
alert(new Date(Date.parse(f)));

// This will alert "Fri Mar 07 2014 08:00:00 GMT+0530 (IST)"
