我使用 jquery 创建了 4 级 megamenu。它根据我的要求工作 80%,有时它在选项卡之间滞后。我对 jquery 不是 100% 满意我们可以进一步改进 jquery 吗?有没有我遗漏的漏洞?如果有人能指出我正确的方向或我做错了什么,我将非常感激(免费更改任何 CSS/HTML)。

注意:一旦子级别窗口打开,它会显示默认 URL

用于 html/css/jquery https://jsfiddle.net/mg02rxra/4/

  <script>

$(function(){
var _timer;
$('#menu > li > a').on("mouseenter",function(){
mainLoad(this); //, 1000);
});
$('#menu').on("mouseleave", function(){
_timer = setTimeout(
showDefault , 100);
}).on("mouseenter", function(){
clearTimeout(_timer);
});

function mainLoad(param){
var li_ = param;
var x = $(param).parent();
var ul_ = x.find(".sublevel1");
$('#menu > li > a').removeClass('active');
$(param).addClass('active');
$('.sublevel1').css('display','none');
$(ul_).css('display','block');
}

function showDefault() {
$('.sublevel1').css('display','none');
$('#menu > li > a').removeClass('active');
}

$('.sublevel1 > div > li > a').on("mouseenter",function(){
var li_ = this;
var x = $(this).parent().index() + 1;
$('.level1-a').removeClass('active');
$('.level1:nth-child(' + x + ') .level1-a').addClass('active');
$('.default, .info').css('display','none');
$('.level1:nth-child(' + x +') .info').css('display','block');
});
$(".xman").on("mouseleave", function(){
_timer = setTimeout(
showDefault2 , 100);
}).on("mouseenter", function(){
clearTimeout(_timer);
});

function showDefault2() {
$('.level1-a').removeClass('active');
$('.info').css('display','none')
$('.default').css('display','block');
}

});
</script>

最佳答案

为什么要使用 jQuery 实现菜单-子菜单功能? Jquery 总是滞后 - 因为它总是执行代码,一旦你完成鼠标。但是你可以通过有效的方式使用 CSS 来做到这一点。请使用此链接获取此功能:http://cssmenumaker.com/menu/opera-drop-down-menu

此外,我附上代码如下
