如何計算javascript中兩個日期之間的天數

Question

我有兩個日期格式爲dd/mm/yyyy。如何計算javascript/jquery中這兩個日期之間的天數。

實施例：FOM日期20/06/2000，迄今爲止是16/08/2011

Answer 1

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圍捕，Math.floor向下舍入。

Answer 2

簡單的代碼

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 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));
