Question

我有两个日期为dd / mm / yyyy格式。如何在javascript / jquery中计算这两个日期之间的天数。

示例：Fom日期是20/06/2000，迄今为止是2011年8月16日

Answer 1

简单代码

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

Answer 2

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。

Answer 3

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));
