我正在创建一个具有四个深度级别的导航菜单，我一次显示3个深度级别，当用户进入深度级别4时，第一个深度级别应向左移动并仅显示第二个，第3，第4深度水平。
但我在这里遇到的问题是，点击深度级别3中的菜单项（没有孩子），菜单也向左移动。
即，点击菜单项1＆gt;菜单项目1.2＆gt;菜单item1.2.2＆GT;菜单item1.2.2.1 这里菜单项1.2.2.1没有孩子，但菜单也向左移动
特别是，如果只有儿童子菜单，如何移动我的菜单？
这是我的代码：
$(document).ready(function(){
$('.menu-item').click(function(event){
event.stopPropagation();
$('.dropdown',this).slideToggle(300);
$('.col ul li').removeClass('active');
$(this).siblings().find(".dropdown").hide();
});
/*sub-col-1.2*/
$('.col ul li').click(function(event){
event.stopPropagation();
$(this).toggleClass('active');
$(this).siblings().find("li").removeClass('active');
//$('.sub-col li').removeClass('active');
//$(this).children().find(".sub-sub-sub-col").hide();
});
/*sub-sub-col*/
$('.col ul li ul').click(function(event){
event.stopPropagation();
$(this).toggleClass('active');
});
$('.sub-sub-col > ul > li').click(function() {
var clicks = $(this).data('clicks');
if (clicks) {
$('.dropdown').animate({
'left' : '0px'
})
}
else {
$('.dropdown').animate({
'left' : '-510px'
})
}
$(this).data("clicks", !clicks);
});
/*sub-sub-sub-col*/
$('.col ul ul li ul').click(function(event){
event.stopPropagation();
$(this).toggleClass('active');
});

答案 0 :(得分：0)
试试这个：
$('.sub-sub-col > ul > li').click(function() {
if(!$(this).find('.sub-sub-sub-col').length){
return false;
}
var clicks = $(this).data('clicks'); //continue your code
});
或者：
if(!$(this).children('.sub-sub-sub-col').length){
return false;
}
<强> ============================================ ====
// if click on sub-col
$('.sub-col > ul > li').on('click', function(){
if (!$(this).hasClass('active')) {
$('.dropdown').animate({
'left' : '10px'
})
}
});
$('.sub-sub-col > ul > li').click(function() {
// var clicks = $(this).data('clicks');
if (!$(this).hasClass('active')) {
$('.dropdown').animate({
'left' : '10px'
})
}
else {
$('.dropdown').animate({
'left' : '-510px'
})
}
// $(this).data("clicks", !clicks);
});
