計算差異之間的兩個時間戳並獲得Unix時間戳差異

Question

我想計算兩個日期時間之間的區別，一個日期是由用戶提交的，另一個是當前時間：

user submitted time - now = difference in unix 

用戶提交的時間格式爲：

2014-03-26 10:52:00 

感謝您的幫助。

Answer 1

你可以簡單地用getTime()返回的毫秒數做到這一點。

var ds = "2014-03-26 10:52:00"; 
var newDate = new Date(ds).getTime(); //convert string date to Date object 
var currentDate = new Date().getTime(); 
var diff = currentDate-newDate; 
console.log(diff); 

有時，在解析日期字符串機會跨瀏覽器的兼容性，因此這是更好地分析它像

var ds = "2014-03-26 10:52:00"; 
var dateArray = ds.split(" "); // split the date and time 
var ds1 = dateArray[0].split("-"); // split each parts in date 
var ds2 = dateArray[1].split(":"); // split each parts in time 
var newDate = new Date(ds1[0], (+ds1[1] - 1), ds1[2], ds2[0], ds2[1], ds2[2]).getTime(); //parse it 
var currentDate = new Date().getTime(); 
var diff = currentDate - newDate; 
console.log(diff); //timestamp difference 

Answer 2

您可以使用MomentJS庫

var user_submited_time = moment('2014-03-26 10:52:00'); 
var now = moment(); 
var value = user_submited_time - now;
