Jquery 导航下拉列表重叠可以'；不能得到正确的z指数
我使用的是引导，我的下拉列表有问题。 我有一些JS，如果下拉列表要碰到窗口边缘，它会改变下拉列表的位置。它将其移动到父下拉列表的另一侧。问题是下拉列表与根下拉列表重叠，z索引关闭 我试着根据我能想到的一切调整z指数，但没有成功。有什么想法吗 HTML: jQuery：Jquery 导航下拉列表重叠可以'；不能得到正确的z指数,jquery,html,css,twitter-bootstrap,Jquery,Html,Css,Twitter Bootstrap,我使用的是引导，我的下拉列表有问题。 我有一些JS，如果下拉列表要碰到窗口边缘，它会改变下拉列表的位置。它将其移动到父下拉列表的另一侧。问题是下拉列表与根下拉列表重叠，z索引关闭 我试着根据我能想到的一切调整z指数，但没有成功。有什么想法吗 HTML: jQuery： $(document).ready(function() { $('.dropdown').parent().hover(function() { var menu = $(this).find("ul");
$(document).ready(function() {
$('.dropdown').parent().hover(function() {
var menu = $(this).find("ul");
var menupos = $(menu).offset();
if (menupos.left + menu.width() > $(window).width()) {
var newpos = -$(menu).width();
menu.css({ left: newpos });
}
});
});
我觉得这里有很多不必要的css样式，但主要是在最后一个ul上缺少了一个z索引（我用newStyle类更新了这个索引）
因此，我可以在您的样式中找到一些变化，但JSFIDLE有其他修改

您是否尝试过为设置z索引的元素指定一个位置，例如位置：绝对？我现在不能测试它，但我知道丢失的位置可能会弄乱z-指数。我查看了位置并确保它已设置。
