更改js代碼將彈出底部

Question

嗨下面的JS代碼將彈出窗口放在頂部。我試圖改變它使彈出頁面到頁面的底部，但它不起作用。關於如何將彈出窗口更改爲頁面底部的任何想法。

(function(window) { 

    if (!!window.cookieChoices) { 
    return window.cookieChoices; 
    } 

    var document = window.document; 
    // IE8 does not support textContent, so we should fallback to innerText. 
    var supportsTextContent = 'textContent' in document.body; 

    var cookieChoices = (function() { 

    var cookieName = 'displayCookieConsent'; 
    var cookieConsentId = 'cookieChoiceInfo'; 
    var dismissLinkId = 'cookieChoiceDismiss'; 

    function _createHeaderElement(cookieText, dismissText, linkText, linkHref) { 
     var butterBarStyles = 'position:fixed;width:100%;background-color:#000000;color:#ffffff;' + 
      'margin:0; left:0; top:0;padding:4px;z-index:1000;text-align:center;'; 

     var cookieConsentElement = document.createElement('div'); 
     cookieConsentElement.id = cookieConsentId; 
     cookieConsentElement.style.cssText = butterBarStyles; 
     cookieConsentElement.appendChild(_createConsentText(cookieText)); 

     if (!!linkText && !!linkHref) { 
     cookieConsentElement.appendChild(_createInformationLink(linkText, linkHref)); 
     } 
     cookieConsentElement.appendChild(_createDismissLink(dismissText)); 
     return cookieConsentElement; 
    } 

    function _createDialogElement(cookieText, dismissText, linkText, linkHref) { 
     var glassStyle = 'position:fixed;width:100%;height:100%;z-index:999;' + 
      'top:0;left:0;opacity:0.5;filter:alpha(opacity=50);' + 
      'background-color:#ccc;'; 
     var dialogStyle = 'z-index:1000;position:fixed;left:50%;top:50%'; 
     var contentStyle = 'position:relative;left:-50%;margin-top:-25%;' + 
      'background-color:#fff;padding:20px;box-shadow:4px 4px 25px #888;'; 

     var cookieConsentElement = document.createElement('div'); 
     cookieConsentElement.id = cookieConsentId; 

     var glassPanel = document.createElement('div'); 
     glassPanel.style.cssText = glassStyle; 

     var content = document.createElement('div'); 
     content.style.cssText = contentStyle; 

     var dialog = document.createElement('div'); 
     dialog.style.cssText = dialogStyle; 

     var dismissLink = _createDismissLink(dismissText); 
     dismissLink.style.display = 'block'; 
     dismissLink.style.textAlign = 'right'; 
     dismissLink.style.marginTop = '8px'; 

     content.appendChild(_createConsentText(cookieText)); 
     if (!!linkText && !!linkHref) { 
     content.appendChild(_createInformationLink(linkText, linkHref)); 
     } 
     content.appendChild(dismissLink); 
     dialog.appendChild(content); 
     cookieConsentElement.appendChild(glassPanel); 
     cookieConsentElement.appendChild(dialog); 
     return cookieConsentElement; 
    } 

    function _setElementText(element, text) { 
     if (supportsTextContent) { 
     element.textContent = text; 
     } else { 
     element.innerText = text; 
     } 
    } 

    function _createConsentText(cookieText) { 
     var consentText = document.createElement('span'); 
     _setElementText(consentText, cookieText); 
     return consentText; 
    } 

    function _createDismissLink(dismissText) { 
     var dismissLink = document.createElement('a'); 
     _setElementText(dismissLink, dismissText); 
     dismissLink.id = dismissLinkId; 
     dismissLink.href = '#'; 
     dismissLink.style.marginLeft = '24px'; 
     return dismissLink; 
    } 

    function _createInformationLink(linkText, linkHref) { 
     var infoLink = document.createElement('a'); 
     _setElementText(infoLink, linkText); 
     infoLink.href = linkHref; 
     infoLink.target = '_blank'; 
     infoLink.style.marginLeft = '8px'; 
     return infoLink; 
    } 

    function _dismissLinkClick() { 
     _saveUserPreference(); 
     _removeCookieConsent(); 
     return false; 
    } 

    function _showCookieConsent(cookieText, dismissText, linkText, linkHref, isDialog) { 
     if (_shouldDisplayConsent()) { 
     _removeCookieConsent(); 
     var consentElement = (isDialog) ? 
      _createDialogElement(cookieText, dismissText, linkText, linkHref) : 
      _createHeaderElement(cookieText, dismissText, linkText, linkHref); 
     var fragment = document.createDocumentFragment(); 
     fragment.appendChild(consentElement); 
     document.body.appendChild(fragment.cloneNode(true)); 
     document.getElementById(dismissLinkId).onclick = _dismissLinkClick; 
     } 
    } 

    function showCookieConsentBar(cookieText, dismissText, linkText, linkHref) { 
     _showCookieConsent(cookieText, dismissText, linkText, linkHref, false); 
    } 

    function showCookieConsentDialog(cookieText, dismissText, linkText, linkHref) { 
     _showCookieConsent(cookieText, dismissText, linkText, linkHref, true); 
    } 

    function _removeCookieConsent() { 
     var cookieChoiceElement = document.getElementById(cookieConsentId); 
     if (cookieChoiceElement != null) { 
     cookieChoiceElement.parentNode.removeChild(cookieChoiceElement); 
     } 
    } 

    function _saveUserPreference() { 
     // Set the cookie expiry to one year after today. 
     var expiryDate = new Date(); 
     expiryDate.setFullYear(expiryDate.getFullYear() + 1); 
     document.cookie = cookieName + '=y; path=/; expires=' + expiryDate.toGMTString(); 
    } 

    function _shouldDisplayConsent() { 
     // Display the header only if the cookie has not been set. 
     return !document.cookie.match(new RegExp(cookieName + '=([^;]+)')); 
    } 

    var exports = {}; 
    exports.showCookieConsentBar = showCookieConsentBar; 
    exports.showCookieConsentDialog = showCookieConsentDialog; 
    return exports; 
    })(); 

    window.cookieChoices = cookieChoices; 
    return cookieChoices; 
})(this); 

謝謝。
