長整型爲Javascript日期格式

Question

我有一個很長的int值：20140307080000.這實際上是datetime 2014-03-07 08:00:00。我已經嘗試過JS中的Date.parse，並將其轉換爲字符串後，但無法將其作爲Javascript日期對象進行檢索。是否有任何JavaScript或D3內置方法將其轉換爲日期對象而不是手動分割它？

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)"
