前端jsp页面实现将字符串类型的日期转化date型并求出两个日期相隔的天数---很实用

javascript 字符串转化为日期

var s="2010-5-18 12:30:20";
var t=new Date(s.replace(/-/g,"/")); 

java代码

<%
    SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd"); 
    Date Acceptdate = dateformat.parse(acceptDate);
    long diffMillis=Acceptdate.getTime()-salvation.getArriveDate().getTime();
    long arrive = diffMillis/(24*60*60*1000);
    String arriveDay=null;
 %>

javascript代码

<script type="text/javascript">
	 function DateChange()
	 {	
	  var starttime=document.getElementById("inDateNull").value;
	  var stoptime=document.getElementById("acceptDateNull").value;
	  var d1 = new Date(starttime.replace(/-/g,"/"));
	  var d2 = new Date(stoptime.replace(/-/g,"/"));
	  var times = d2.getTime()-d1.getTime();
	  var days = times/(24*60*60*1000);
	  document.getElementById("b1").value=days;
	 }
	 </script>
