IE7 未加载 JavaScript 文件

互联网上有很多关于这个问题的信息，但是我找不到与此非常具体的东西。

我一直在用新的欧盟cookie法律信息（javascript）更新网站。我刚刚注意到 ie7 没有加载 javascript 文件。已测试警报，但未显示。

脚本包括：

<script src="http://code.jquery.com/jquery-latest.js"></script> 
<script src="cookiesJs/jquery.cookie.js"></script>
<script src="cookiesJs/c.js"></script>

c.js：

document.write('<style type="text/css">a{text-decoration: none;}#cookieMessage {font-family: Arial, Helvetica, sans-serif;color: #222;background-color: #D1D3D4;padding: 8px;height: auto;position: fixed;width:200px;margin: 0px 0px 0 0;bottom:0px;right:10px;border:#FFF 2px solid;border-bottom:0px;padding: 0px 8px 8px 8px;-moz-border-radius-topleft: 8px;-moz-border-radius-topright: 8px;-webkit-border-top-left-radius: 8px;-webkit-border-top-right-radius: 8px;border-top-right-radius: 8px;border-top-left-radius: 8px;text-align:left;overflow:hidden;z-index:999999;}#cookieMessage h6 {font-size: 14px;text-transform: uppercase;padding: 0px;margin-top: 8px;margin-right: 0px;margin-bottom: 5px;margin-left: 0px;color: #222;}#cookieMessage img {border:0px;}#cookieMessage p {text-align: left;font-size: 11px;padding: 0px;margin-top: 0px;margin-right: 0px;margin-bottom: 2px;margin-left: 0px;color: #222;}#cookieMessage p a {color: #333;}#cookieMessage h6 a {color: #333;text-decoration: none;}#arrow{margin-top: -20px;}</style>');

      if ( results )
        return ( unescape ( results[2] ) );
      else
        return null;
    }
var x = get_cookie("consentCookie");
    if(x == null){
        document.cookie = "consentCookie=yes; path=/";
        location.reload();
    }var x = get_cookie("consentCookie");

        document.write(policy);

        // if they have visited before but not accepted
        document.write('<div id="cookieMessage">');
        var policy = '<a href="#_" id="polup"><h6>Cookie Policy</h6> <img id="arrow" align="right" src="cookiesJs/cookieimg/arrow.gif" width="18" height="14" alt="arrow" /></a></h6>';
        document.write(policy);
        document.write('<p>Our website uses cookies.

        $("#cookieMessage").css("height","20");
    }else{
        //if they  have visited and accepted
        document.write('<div id="cookieMessage" style="display: none"><h6>Cookie Policy</h6></div>');
    }

我不明白为什么IE不加载文件。
