                </td>
            </tr>
</table>
<?php require "footer.php" ;?>

当我将鼠标悬停在导航中的帐户菜单上时，会出现下拉菜单。但是当我离开下拉菜单时，它并没有消失。我的代码有什么问题请帮忙？？

只有您的内联 jQuery 工作，而不是<script>代码块中的 jQuery。

因此，修改您的锚标记如下：

<a href="javascript:void(0);" onmouseover=" $('#droptwo').css({'left':'325px'});"  onmouseout="$('#droptwo').css({'left':'-1000px'});" class="menu" style="color:#FFFFFF;">&nbsp;Account&nbsp;</a>

它会起作用。

要使您的 jQuery 代码块工作，首先从锚标记中删除内联 javascript：

<a href="javascript:void(0);" class="menu" style="color:#FFFFFF;">&nbsp;Account&nbsp;</a>

然后修改你的jQuery代码块：

$(document).ready(function() {

    $('#droptwo').css({'left':'-1000px'});

    $("span > a").hover(
        function() {
            $('#droptwo').css({'left':'325px'});       
        },
        function() {
            $('#droptwo').css({'left':'-1000px'});
        }
    );
}); //END document.ready
