我正在尝试在 li 中添加一个 div 并显示为与 mouseEnter 事件关联。如果我将 div 附加到文档中，就会出现问题，看起来很棒。像这样
$(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，当我尝试附加相同的 div 但附加到 li 时，实际上不起作用
$(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();
有什么问题吗？？？
这是html

最佳答案
您正在重新发明轮子 - 更糟糕的是，以一种非常复杂的方式。
您只能使用 HTML 和 CSS 获得“悬停菜单”。 (加上最少量的 JS 来伪造:在旧的、不兼容的浏览器中悬停……)
阅读the article在 HTMLDog 中学习它，或者只看 the working example .
(Vertical menus 也是完全可能的。)
如果您觉得自己编写它很复杂(不是很难，但是......)，也有 javascript 库可以为您完成这些菜单，例如 Suckerfish .
希望这对您有所帮助 - 下次，请先搜索! :)
