我有两个日期是年月日。如何在javascript/jquery中计算这两个日期之间的天数。

示例:from date为20/06/2000,to date为16/08/2011

简单代码

var Date1 = new Date (2008, 7, 25);
var Date2 = new Date (2009, 0, 12);
var Days = Math.round((Date2.getTime() - Date1.getTime())/(1000*60*60*24));

var date1 = new Date(2000, 6, 20);
var date2 = new Date(2011, 8, 16);
var one_day = 1000*60*60*24; //Get 1 day in milliseconds
var days = Math.ceil( (date2.getTime() - date1.getTime() ) / one_day);

Math.ceil向上舍入，Math.floor向下舍入。

t1="10/10/2006";
t2="15/10/2006";
//Total time for one day
var one_day=1000*60*60*24;  //Here we need to split the inputed dates to convert them into standard format for further execution
var x=t1.split("/");     
var y=t2.split("/");   //date format(Fullyear,month,date) 
var date1=new Date(x[2],(x[1]-1),x[0]);
// it is not coded by me,but it works correctly,it may be useful to all
var date2=new Date(y[2],(y[1]-1),y[0])
var month1=x[1]-1;
var month2=y[1]-1;
//Calculate difference between the two dates, and convert to days
_Diff=Math.ceil((date2.getTime()-date1.getTime())/(one_day));
