CSS+JQ实现炫酷导航栏_html/css_WEB-ITnose
一步一步的学习,后面再做个综合页面
1.当前页面高亮显示的导航栏
首先是HTML代码,很简单,ul+li实现菜单
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>导航栏一</title></head><body> <header class="header"> <div class="nva"> <ul class="list"> <li><a href="Android.html">Android</a></li> <li><a href="C++.html">C++</a></li> <li><a href="IOS.html">IOS</a></li> <li><a href="Java.html">Java</a></li> <li><a href="Ruby.html">Ruby</a></li> </ul> </div> </header><h1 id="首页">首页</h1></body></html>
基本效果:
接下来设置CSS属性,这里要注意标签a是行级元素,所以需要用display转成块级元素,这个很常用,还有就是line-height的常见用法
*{ margin:0; padding: 0;}a{ text-decoration: none;}.nva{ width: 100%; height: 40px; margin-top: 70px; background-color: #222;}.list{ width: 80%; height: 40px; margin: 0 auto; list-style-type: none;}.list li{ float: left;}.list li a{ padding: 0 30px; color: #aaa; line-height: 40px; display: block;}.list li a:hover{ background:#333; color:#fff;}.list li a.on{ background:#333; color:#fff;}h1{ margin: 20px auto; text-align: center;}实现的效果:
最后就是JS动态添加定位效果了
js里面这样考虑,页面跳转就会有链接,根据链接的后缀来匹配属性,匹配则更改样式即可达到想要的效果
需要注意的就是如何获取URL,如何从URL里面查找出href信息
$(function(){ //当前链接以/分割后最后一个元素索引 var index = window.location.href.split("/").length-1; //最后一个元素前四个字母,防止后面带参数 var href = window.location.href.split("/")[index].substr(0,4); if(href.length>0){ //如果匹配开头成功则更改样式 $(".list li a[href^='"+href+"']").addClass("on"); //[attribute^=value]：匹配给定的属性是以某些值开始的元素。 }else { //默认主页高亮 $(".list li a[href^='index']").addClass("on"); }});效果图
2.划入自动切换的导航条
在1的基础上,修改一下HTMLa标签内容,然后通过CSS设置动画效果
<ul class="list"> <li><a href="index01.html"> <b>首页</b> <i>Index</i> </a></li> <li><a href="Android.html"> <b>Android</b> <i>安卓</i> </a></li> <li><a href="C++.html"> <b>C++</b> <i>谁加加</i> </a></li> <li><a href="IOS.html"> <b>IOS</b> <i>苹果</i> </a></li> <li><a href="Java.html"> <b>Java</b> <i>爪哇</i> </a></li> <li><a href="Ruby.html"> <b>Ruby</b> <i>如八一</i> </a></li> </ul>
CSS实现动画效果,首先把b和i标签都设置为块级元素,这样的话就可以垂直分布,再给a设置一个transition,所谓的动画,就是划入后改变把a上移,再给a加个边框好观察,看下图
最后想实现效果,就给包裹菜单的div设置一个溢出隐藏属性即可
*{ margin:0; padding: 0;}a{ text-decoration: none;}.nva{ width: 100%; height: 40px; margin-top: 70px; background-color: #222; overflow: hidden;}.list{ width: 80%; height: 40px; margin: 0 auto; list-style-type: none;}.list li{ float: left;}.list li a{ padding: 0 30px; color: #aaa; line-height: 40px; display: block; transition: 0.3s;} .list b,.list i{ display: block; }.list li a:hover{ margin-top: -40px; background:#333; color:#fff;}.list li a.on{ background:#333; color:#fff;}h1{ margin: 20px auto; text-align: center;}
也可以采用JQ来实现,代码如下
$(function () { $(".list a").hover(function () { //stop是当执行其他动画的时候停止当前的 $(this).stop().animate({ "margin-top": -40 }, 300); }, function () { $(this).stop().animate({ "margin-top": 0 }, 300); });});3.弹性子菜单实现
首先子菜单使用div包裹,里面都是a标签,如下
<li><a href="Android.html"> <b>Android</b> </a> <div class="down"> <a href="#">子菜单1</a> <a href="#">子菜单2</a> <a href="#">子菜单3</a> <a href="#">子菜单4</a> </div> </li>
接下来设置样式,既然是子菜单,就要脱离文档页面,所以使用absolute属性,使用这个属性那么父容器就要是relative
*{ margin:0; padding: 0;}a{ text-decoration: none;}.nva{ width: 100%; height: 40px; margin-top: 70px; background-color: #222; position: relative;}.list{ width: 80%; height: 40px; margin: 0 auto; list-style-type: none;}.list li{ float: left;}.list li a{ padding: 0 30px; color: #aaa; line-height: 40px; display: block; transition: 0.3s;}.list b{ display: block;}.list li a:hover{ background:#333; color:#fff;}.list li a.on{ background:#333; color:#fff;}.list .down{ position: absolute; top: 40px; background-color: #222; /*display: none;*/}.list .down a{ color: #aaa; padding-left: 30px; display: block;}h1{ margin: 20px auto; text-align: center;}如下效果:
接下来使用JQ和easing插件来控制动画
find方法一般用来查找操作元素的后代元素的
$(function () { $(".list li").hover(function () { //这里使用了easing插件 $(this).find(".down").stop().slideDown({duration:1000,easing:"easeOutBounce"}); }, function () { $(this).find(".down").stop().slideUp({duration:1000,easing:"easeOutBounce"}); });});效果,图片录制不太好,实际上都是弹性动画的
