我使用的是 3 级下拉菜单，它本身可以正常工作，但在添加到我的 magento 模板时会发生冲突。我添加了 $.noConflict(true);这解决了一些问题，但我仍然收到未捕获的类型错误，而且下拉菜单的第 3 级未显示。

javascript 代码放在模板底部之前
<script src="js/jquery-1.9.1.min.js" type="text/javascript"></script>
<script src="js/jquery/jquery.menu-aim.js" type="text/javascript"></script>
<script src="js/bootstrap.min.js" type="text/javascript"></script>

$.noConflict(true);
var $menu = $(".dropdown-menu");
// jQuery-menu-aim: <meaningful part of the example>
// Hook up events to be fired on menu row activation.
$menu.menuAim({
activate: activateSubmenu,
deactivate: deactivateSubmenu
});
// jQuery-menu-aim: </meaningful part of the example>
// jQuery-menu-aim: the following JS is used to show and hide the submenu
// contents. Again, this can be done in any number of ways. jQuery-menu-aim
// doesn't care how you do this, it just fires the activate and deactivate
// events at the right times so you know when to show and hide your submenus.
function activateSubmenu(row) {
var $row = $(row),
submenuId = $row.data("submenuId"),
$submenu = $("#" + submenuId),
height = $menu.outerHeight(),
width = $menu.outerWidth();
// Show the submenu
$submenu.css({
display: "block",
top: -1,
left: width - 3, // main should overlay submenu
height: height - 4 // padding for main dropdown's arrow
});
// Keep the currently activated row's highlighted look
$row.find("a").addClass("maintainHover");
}
function deactivateSubmenu(row) {
var $row = $(row),
submenuId = $row.data("submenuId"),
$submenu = $("#" + submenuId);
// Hide the submenu and remove the row's highlighted look
$submenu.css("display", "none");
$row.find("a").removeClass("maintainHover");
}
// Bootstrap's dropdown menus immediately close on document click.
// Don't let this event close the menu if a submenu is being clicked.
// This event propagation control doesn't belong in the menu-aim plugin
// itself because the plugin is agnostic to bootstrap.
$(".dropdown-menu li").click(function(e) {
e.stopPropagation();
});
$(document).click(function() {
// Simply hide the submenu on any click. Again, this is just a hacked
// together menu/submenu structure to show the use of jQuery-menu-aim.
$(".popover").css("display", "none");
$("a.maintainHover").removeClass("maintainHover");
});

最佳答案
从 $(".dropdown-menu"); 获取 null 意味着它不是由 jQuery 呈现的，而是由其他库呈现的，看起来你不是正确使用 .noConflict。
试试这个:
$.noConflict(true);
var $menu = jQuery(".dropdown-menu");
//...
