这里有点 jquery 新手，所以放轻松。
基本上我正在尝试将 hoverIntent 插入此下拉菜单：
http://www.sooperthemes.com/open-source/jquery/jquery-sooperfish-dropdown-menus
我已经坚持了几天了，我知道这可能很简单，但我似乎找不到合适的选择器来应用意图函数。
任何帮助，将不胜感激。
- 更新 -
我想我几乎拥有它，只是有些不太对劲。我已经更新了下面的js。
悬停意图代码位于底部
$.fn.sooperfish = function(op) {
var sf = $.fn.sooperfish;
sf.o = [];
sf.op = {};
sf.c = {
menuClass : 'sf-js-enabled',
isParent : 'sf-parent',

if ($.easing.easeOutOvershoot) { //set default easing
sooperEasingShow = 'easeOutOvershoot';
} else {
sooperEasingShow = 'linear';
};
if ($.easing.easeInTurbo) {
sooperEasingHide = 'easeInTurbo';
} else {
sooperEasingHide = 'linear';
};
sf.defaults = {
multiColumn : true,
dualColumn : 12, //if a submenu has at least this many items it will be divided in 2 columns
tripleColumn : 18, //if a submenu has at least this many items it will be divided in 3 columns
hoverClass : 'sfHover',
delay : 500, //make sure menus only disappear when intended, 500ms is advised by Jacob Nielsen
animationShow : {height:'show',delay:'500'},
