div的位置问题

我试图在li中添加一个div，并且似乎与mouseEnter事件相关联。问题是如果我将div附加到文档看起来很棒。像这样div的位置问题

$(document.body).append('<div id="subMenu" class="ui-state-hover" style="width:150px;height:200px; float: left;">subCategory</div>'); 
$("#subMenu").css({ 
     position:'absolute', 
     top: $(this).offset().top, 
     left: ($(this).offset().left + $(this).width()) 
    }).show();

现在，当我尝试添加同一div但李并没有在实际上

$(document.body).append('<div id="subMenu" class="ui-state-hover" style="width:150px;height:200px; float: left;">subCategory</div>'); 
$("#subMenu").css({ 
     position:'absolute', 
     top: $(this).offset().top, 
     left: ($(this).offset().left + $(this).width()) 
    }).show();

here's a video

工作出了什么问题？ ??

这是HTML

跳出来的一件事（略有不相关）是您使用表格进行布局。只有一行或多行但只有一列的表格可能不是表格的最佳使用，因为它们往往会混淆代码。 – BryanH

最有可能的<div>位置是绝对的其父母之一。

试过给.menuCat liposition:relative;？

不要忘记相应地编辑top和left值。

感谢您的回答，您的解决方案由好的行给予。感谢您的帮助 – Jorge

您正在以一种非常复杂的方式重塑车轮 - 更糟的是，
只能使用HTML和CSS获得“悬停菜单”。（加上最小数量的JS虚假：悬停在旧的，不兼容的浏览器中......）

在HTMLDog中阅读the article以了解它，或者只是看看the working example。
（Vertical menus是完全可能的。）

如果你觉得复杂就自己写（不用这么辛苦，但是......），也有JavaScript库做这些菜单为您，如Suckerfish。

我希望这有助于 - 下一次，先搜索！ :)

我必须同意@ANeves ...由于不必要的原因，代码非常麻烦，而不是有必要创建混乱的代码！ –
