本文将持续添加我自己用原生JS写的各种菜单特效,虽然网上一搜一大堆,但我还是喜欢自己来写一写!
这是上一篇:Javascript实战(带收放动画效果的导航菜单)
下面是经过优化后的完整代码,优化了CSS样式、简化事件函数、减少HTML层级,删了至少20行以上的冗余代码
*{ margin: 0; padding: 0; } a,img{border:0;} ul{ position: absolute; top: 20px; left: 30px; z-index: 100; } #ul li{ display: inline-block; position: relative; height: 30px; text-align: center; line-height: 30px; padding: 3px; border: 1px solid gray; border-radius: 10px 10px 0 0; background-color: aliceblue; cursor: pointer; -webkit-transition: all ease-in-out 0.3s; -moz-transition: all ease-in-out 0.3s; -ms-transition: all ease-in-out 0.3s; -o-transition: all ease-in-out 0.3s; transition: all ease-in-out 0.3s; } #ul li:hover{background-color: aquamarine;} .nav-div{ position: absolute; width: 100%; left: -1px; top: 37px; display: none; border: 1px solid gray; border-top: 0; border-radius:0 0 10px 10px; background-color: aliceblue; } .show-hide{ position: relative; display: block; border-radius:0 0 10px 10px; background-color: lightblue; -webkit-transition: all ease-in-out 0.3s; -moz-transition: all ease-in-out 0.3s; -ms-transition: all ease-in-out 0.3s; -o-transition: all ease-in-out 0.3s; transition: all ease-in-out 0.3s; border-bottom: 1px solid gray; } .show-hide:hover{background-color: lavender} .a-div{ background-color: aliceblue; display: none; border-radius:0 0 10px 10px; opacity: 0} .a{ z-index: -1; display: block; text-decoration: none; border-radius:10px; -webkit-transition: all ease-in-out 0.3s; -moz-transition: all ease-in-out 0.3s; -ms-transition: all ease-in-out 0.3s; -o-transition: all ease-in-out 0.3s; transition: all ease-in-out 0.3s; } .a:hover{background-color: lavender}

下面是第二个特效:(具体实现比第一个简单很多,主要注意CSS布局)
*{ margin: 0; padding: 0; } a,img{border:0;} #menu{ position: absolute; top: 30px; left: 0; right: 0; margin: auto; width: 400px; border-left: 1px solid gray; border-top: 1px solid gray; background-color: lemonchiffon; text-align: center; } #menu li{ list-style: none; float: left; width: 99px; height: 30px; line-height: 30px; border-right: 1px solid gray; background-color: burlywood; color: white; -webkit-transition: all ease-in-out 0.5s; -moz-transition: all ease-in-out 0.5s; -ms-transition: all ease-in-out 0.5s; -o-transition: all ease-in-out 0.5s; transition: all ease-in-out 0.5s; } #menu li:hover{ background-color: lemonchiffon; color: #336699; } .contain{ position: absolute; left: -1px; display: none; width: 399px; height: 300px; color: #336699; border-left: 1px solid gray; border-right: 1px solid gray; border-bottom: 1px solid gray; background-color: lemonchiffon; }
