我使用jQuery在我的website上轉置吉他和絃，但由於某種原因，它不能在Internet Explorer中工作，但適用於其他任何瀏覽器。請幫忙。jquery無法在Internet Explorer中工作？

你可以發佈一些代碼或錯誤消息，以便我們可以幫助你更多？ – 2011-01-21 20:13:53

Im 99.9999999％肯定它不是jQuery。當談到它的JavaScript語法寬容時，Internet Explorer更加挑剔。例如，如果您的JS代碼中有額外的逗號，則Chrome和FireFix可能會忽略它，而Internet Explorer會崩潰。

您需要向我們提供一些代碼或至少一條錯誤消息，或者幫助我們瞭解您的問題。

我從來沒有碰過JS代碼;我只複製並將其粘貼到相應的文件夾中。它來自我從http://codegavin.com/projects/transposer下載的插件，但這裏是jquery.transposer.js代碼：

這是我的代碼，我把其中的和絃在頁面上：

    <script type="text/javascript"> 
    $(function() { 
     $("pre").transpose(); 
    }); 
    </script> 
    <link rel="stylesheet" type="text/css" href="jquery.transposer.css" /> 

    <pre class="content" data-key="G"> 
G   D    Em 
I sing a simple song of love 
     C Em  D 
To my Savior, to my Jesus. 
G    D     Em 
I'm grateful for the things You've done, 
      C Em    D 
My loving Savior, my precious Jesus. 

Am   Em    D    G 
My heart is glad that You've called me Your own. 
Am   Em    D 
There's no place I'd rather be than 

     G D C 
In Your arms of love, 
     G D C 
In Your arms of love, 
      Em  D   C 
Holding me still, holding me near, 
       G 
In Your arms of love. 
    </pre>
