檢查日期大於2天，從今天的日期的JavaScript

Question

我需要檢查的日期比當前日期增量更大兩天計數和顯示

JS代碼：

> var exceeds = 0; 
>   var date = "25-02-2015"; 
>   var today = new Date(); 
>   if((new Date(today.getFullYear(), today.getMonth(), today.getDate()+2))>date) { exceed+=1; } 
> 
> console.log(exceeds); 

Answer 1

var exceeds = 0; 
var date = "25-02-2015", date_val = date.split("-"); 

// Getting timestamp of date 
var otherDate = new Date(+date_val[2], +date_val[1], +date_val[0]).getTime(); 

// Get the timestamp for 2 days from now: 
var timestamp = new Date().getTime() + (2* 24 * 60 * 60 * 1000) 
if(otherDate>timestamp) exceeds++; 

Answer 2

var today = new Date(); 
var dd = today.getDate(); 
var mm = today.getMonth()+1; //January is 0! 
var yyyy = today.getFullYear(); 

if(dd<10) { 
    dd='0'+dd 
} 

if(mm<10) { 
    mm='0'+mm 
} 

today = mm+'/'+dd+'/'+yyyy; 
document.write(today); 
var currentDate = "03/23/2015"; 
if(today <= currentDate){ 
alert('yes'); 
} 

Answer 3

您可以將您的日期轉換爲Unix TimeStamp，這是從1970-01-01 00:00:00到您的特定日期的毫秒數。 那麼，有代碼

var yourDate = new Date(Date.UTC(2015, 02, 25)).getTime(); //Get the timestamp 
var today = new Date().getTime();   
if(today - yourDate > 60 * 60 * 1000 * 24 * 2){alert('greater than 2 days')}
