將字符串作爲變量傳遞到JavaScript函數不起作用

Question

我陷入了一個令人尷尬的簡單問題。我非常瞭解ASP.NET，但我沒有那麼好。我的主頁上有一個精彩的倒計時鐘，它使用各種JavaScript文件。我找到了存儲結束日期的文件，它是一個靜態值。

$(".count-down").ccountdown(2016,12,25,'10:00'); 

我想讀的是從我的數據庫填充，從而使他人在CMS可以設置一個管理面板中值hiddenfield的日期。我編碼如下：

var countdowndate = document.getElementById('hdnCountdownDate').value; 
//alert(countdowndate); 
$(".count-down").ccountdown(countdowndate); 

（注;所述.ccountdown是不是一個錯字）

的ASP.NET字段;

<form runat="server"> 
    <asp:HiddenField ID="hdnCountdownDate" runat="server" /> 
</form> 

主頁的代碼隱藏設置隱藏字段值;

hdnCountdownDate.Value = "2016,12,25,'10:00'" 

我把警報的變量的聲明和設置後，它會給出確切的相同的值靜態的，但是當我換變量與靜態文本的功能，它僅適用。有人能幫助我嗎？

呈現的HTML是;

<input type="hidden" name="ctl00$hdnCountdownDate" id="hdnCountdownDate" value="2016,12,25,'10:00'"> 

我試着將countdowndate變量拆分成它的變量變量，但是sitll不起作用;

var countdowndate = document.getElementById('hdnCountdownDate').value; 
var resarray = countdowndate.split(","); 
$(".count-down").ccountdown(resarray[0],resarray[1],resarray[2],resarray[3]); 

JS函數是;

(function($) { 
$.fn.ccountdown = function(_yr, _m, _d, _t) { 
    var $this = this; 
    var _montharray = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec") 
    var _today = new Date(); 
    // calling function first time so that it wll setup remaining time 
    var _changeTime = function() { 
     var _today = new Date(); 
     var _todayy = _today.getYear(); 
     if (_todayy < 1000) 
      _todayy += 1900; 
     var _todaym = _today.getMonth(); 
     var _todayd = _today.getDate(); 
     var _todayh = _today.getHours(); 
     var _todaymin = _today.getMinutes(); 
     var _todaysec = _today.getSeconds(); 
     _todaysec = "0" + _todaysec; 
     _todaysec = _todaysec.substr(_todaysec.length - 2); 
     var _todaystring = _montharray[_todaym] + " " + _todayd + ", " + _todayy + " " + _todayh + ":" + _todaymin + ":" + _todaysec; 
     var _futurestring = _montharray[_m - 1] + " " + _d + ", " + _yr + " " + _t; 
     /* calculation of remaining days, hrs, min, and secs */ 
     _dd = Date.parse(_futurestring) - Date.parse(_todaystring); 
     _dday = Math.floor(_dd/(60 * 60 * 1000 * 24) * 1); 
     _dhour = Math.floor((_dd % (60 * 60 * 1000 * 24))/(60 * 60 * 1000) * 1); 
     _dmin = Math.floor(((_dd % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000))/(60 * 1000) * 1); 
     _dsec = Math.floor((((_dd % (60 * 60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) % (60 * 1000))/1000 * 1); 
     var el = $($this); 
     var $ss = el.find(".second"), $mm = el.find(".minute"), $hh = el.find(".hour"), $dd = el.find(".days"); 
     $ss.val(_dsec).trigger("change"); 
     $mm.val(_dmin).trigger("change"); 
     $hh.val(_dhour).trigger("change"); 
     $dd.val(_dday).trigger("change"); 
}; 
    _changeTime(); 
    setInterval(_changeTime, 1000); 
}; 

})(jQuery);

您需要將4個參數傳遞給.ccountdown()：年，月，日和時間字符串。

在您的代碼中，您只傳遞一個參數，該參數是從輸入中獲取的字符串。
