倒数计时器重置刷新

Question

我想实现这个倒计时：http://codepen.io/ltzngr/pen/ysowF

每次页面加载，它重置！我不希望它重置，我希望它继续倒计时到2014年10月3日。

任何帮助将不胜感激！ :)

$(function() { 

var target_date = new Date().getTime() + (39000*3600*48); // set the countdown date 
var days, hours, minutes, seconds; // variables for time units 

var countdown = document.getElementById("tiles"); // get tag element 

getCountdown(); 

setInterval(function() { getCountdown(); }, 1000); 

function getCountdown(){ 

    // find the amount of "seconds" between now and target 
    var current_date = new Date().getTime(); 
    var seconds_left = (target_date - current_date)/1000; 

    days = pad(parseInt(seconds_left/86400)); 
    seconds_left = seconds_left % 86400; 

    hours = pad(parseInt(seconds_left/3600)); 
    seconds_left = seconds_left % 3600; 

    minutes = pad(parseInt(seconds_left/60)); 
    seconds = pad(parseInt(seconds_left % 60)); 

    // format countdown string + set tag value 
    countdown.innerHTML = "<span>" + days + "</span><span>" + hours + "</span><span>" + minutes + "</span><span>" + seconds + "</span>"; 
} 

function pad(n) { 
    return (n < 10 ? '0' : '') + n; 
} 

}）;

集此字符串

 var target_date = new Date().getTime() + (39000*3600*48); // 

至十月

   // year, month, day, hours, minutes, seconds, milliseconds 
       var target_date = new Date(2014, 10, 3, 0, 0, 0, 0);
