swiper.js http://www.swiper.com.cn/ 官方网站,下载的类库和要用那些api我们都需在这里查找
http://www.swiper.com.cn/demo/senior/index.html各种效果,我们要做的就是这种
我们简单发现,就是每一屛会出现动画(css3 animation),切换的当前屏会重新执行动画,可推出,没显示的屏删除了动画
看我们发现了什么?看第一张firebug截图
每一屛就是一个section标签, 在当前显示的section上有了其他兄弟没有的 swiper-slide-active类名
再看当前显示的section下的子标签通过这个swiper-slide-active 类添加了什么,截图
看右侧,发现了,section有swiper-slide-active 类名下的元素添加了animation动画处理
我们已经可以得出原理了
当前显示的那一屏,就是那个section标签有一个swiper-slide-active 类名
有了swiper-slide-active 类名,他下面的子元素会添加css3动画效果(动画css样式)
我们的动画样式就是挂在在swiper-slide-active下面的,通过添加删除这个类名,实现下面元素动画的有无(当前那一屏动画的有无)
我们总结如下
初始
<section class="swiper-slide-active">第一屏</section> 带有类名 swiper-slide-active,所以下面的元素有了动画效果
<section>第二屏</section>
<section>第三屏</section>
滑动到下一屏
<section>第一屏</section> 删除类名swiper-slide-active
<section class="swiper-slide-active">第二屏</section> 带有类名 swiper-slide-active,所以下面的元素有了动画效果
<section>第三屏</section> 删除类名swiper-slide-active
我们先来最简单的例子,最后在套用这个swiper插件
做一个带动画显示内容的tab切换效果,下面是代码,加载好jquery,复制粘贴查看效果
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>css3</title> <style> /* yu she */ *{ margin:0; padding:0;} a{ text-decoration:none;} img{ border:none;} ul{ list-style:none;} body{ color:#222121; font-size:15px; font-family:"宋体"; background-color:#fefefe} .clearfix:after{ content:"."; display:block; height:0; clear:both; overflow:hidden;} .clearfix{ zoom:1;} /*clear*/ .left{float:left;} .right{float:right;} .clear{clear:both;} .wrapper{margin:0 auto;width:1000px;} /*=========main========*/ .demo{ width:350px; margin:20px; float:left;} .tab-list1{ height:40px; line-height:40px;} .tab-list1 span{ color:#0CC; margin:0 10px; cursor:pointer;} .tab-list1 span:hover{color:#F33;} .tab-list1 span.adstyle1{ color:#F33;} .tab-con1{ width:300px; height:300px; background:#CC9; position:relative;} .tab-con1 div{position:absolute; left:150px; top:150px;transition:all .6s ease-in .2s; opacity:0; width:0px; height:0px; overflow:hidden;} .tab-con1 div.addss1{opacity:1; left:0px; top:0px; width:300px; height:300px;} </style> </head> <body> <div class="demo"> <div class="tab-list1"> <span class="adstyle1">第一个</span> <span>第二个</span> <span>第三个</span> </div> <div class="tab-con1"> <div class="addss1">1111111 * @param str 检验的内容 * @param cType 预设的检验规则 字符串</div> <div>222222222 * @param str 检验的内容 * @param cType 预设的检验规则 字符串</div> <div>3333333 * @param str 检验的内容 * @param cType 预设的检验规则 字符串</div> </div> </div> </body> <script src="js/jquery-1.10.2.js"></script> <script type="text/javascript"> $(document).ready(function(){ $(".tab-list1").children().click(function(){ $(this).addClass("adstyle1").siblings().removeClass("adstyle1"); $(".tab-con1").children().eq($(this).index()).addClass("addss1").siblings().removeClass("addss1"); }); }); </script> </html>
看见效果了吧!每次切换到对象显示内容,内容是动画出现的,核心js处理
$(".tab-con1").children().eq($(this).index()).addClass("addss1").siblings().removeClass("addss1");
});
切换显示的内容会添加类名 addss2(这个作用就是那个active类名作用),在这个类名下会加载动画样式,
根据原理我们做了这种切换动画的最简单实现
下面我们拿出一套swiper全屏模板,代码如下
<!doctype html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0,user-scalable=yes, minimum-scale=1.0, maximum-scale=1.5" id="viewport" /> <title>Demo</title> <link rel="stylesheet" href="css/idangerous.swiper.css"> <style> /* Demo Styles */ html { height: 100%; } body { margin: 0; font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: 1.5; position: relative; height: 100%; } .swiper-container { width: 100%; height: 100%; color: #fff; text-align: center; } .pagination { position: absolute; z-index: 20; left: 10px; bottom: 10px; } .swiper-pagination-switch { display: block; width: 8px; height: 8px; border-radius: 8px; background: #555; margin: 0 0px 5px; opacity: 0.8; border: 1px solid #fff; cursor: pointer; } .swiper-active-switch { background: #06F; } #wipeprev{ position: absolute; z-index: 20; left: 50%; top: 30px; width:20px; height:80px; margin-left:-10px; background:#999;} #swipernext{position: absolute; z-index: 20; left: 50%; bottom: 30px; width:20px; height:80px; margin-left:-10px; background:#999;} /*main*/ .ping1{ background:#FC6;} .ping2{ background:#C6C;} .ping3{ background:#0CF;} .ping1 p,ping2 p,ping3 p{ font-size:15px; text-align:center;} </style> </head> <body> <div> <div> <div class="swiper-slide ping1"> <p>第一屏</p> </div> <div class="swiper-slide ping2"> <p>第二屏</p> </div> <div class="swiper-slide ping3"> <p>第三屏</p> </div> </div> <div></div> </div> <script src="js/jquery-1.10.1.min.js"></script> <script src="js/idangerous.swiper-2.1.min.js"></script> <script> var mySwiper = new Swiper('.swiper-container',{ mode: 'vertical', //loop: true, pagination: '.pagination', paginationClickable: true, resistance: false, speed: 0.1, onSlideChangeEnd : function(swiper){ //mySwiper.activeLoopIndex //mySwiper.activeIndex==0){ } }); </script> </body> </html>
swiper不是基于jq的,可有可无,swiper的css文件和js文件是插件必须的,调用插件代码如下(有一篇博文介绍了插件开发)
var mySwiper = new Swiper('.swiper-container',{ mode: 'vertical', //loop: true, pagination: '.pagination', paginationClickable: true, resistance: false, speed: 0.1, onSlideChangeEnd : function(swiper){ //mySwiper.activeLoopIndex //mySwiper.activeIndex==0){ } });
那些解释可以去api查看,onSlideChangeEnd是滑动结束事件,里面我们可以做回调处理,没有事件没么联系后台
我们firebug发现,原理同分析一样,当前屏会添加一个 swiper-slide-active 类名
我们把动画css都写在插件提供的切换类名下就好了,相比tab切换实例去自己设置active简洁多了
我们在<div class="swiper-slide ping2"> 下添加子结构,提供动画源,在style添加基于swiper-slide-active的动画css样式
修改后代码如下
<!doctype html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0,user-scalable=yes, minimum-scale=1.0, maximum-scale=1.5" id="viewport" /> <title>Demo</title> <link rel="stylesheet" href="css/idangerous.swiper.css"> <style> /* Demo Styles */ html { height: 100%; } body { margin: 0; font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: 1.5; position: relative; height: 100%; } .swiper-container { width: 100%; height: 100%; color: #fff; text-align: center; } .pagination { position: absolute; z-index: 20; left: 10px; bottom: 10px; } .swiper-pagination-switch { display: block; width: 8px; height: 8px; border-radius: 8px; background: #555; margin: 0 0px 5px; opacity: 0.8; border: 1px solid #fff; cursor: pointer; } .swiper-active-switch { background: #06F; } #wipeprev{ position: absolute; z-index: 20; left: 50%; top: 30px; width:20px; height:80px; margin-left:-10px; background:#999;} #swipernext{position: absolute; z-index: 20; left: 50%; bottom: 30px; width:20px; height:80px; margin-left:-10px; background:#999;} /*main*/ .ping1{ background:#FC6;} .ping2{ background:#C6C;} .ping3{ background:#0CF;} .ping1 p,ping2 p,ping3 p{ font-size:15px; text-align:center;} .base1{ height:200px; width:200px; margin:100px; background:#FFF; border-radius:100px;} .base2{height:200px; width:200px; margin:100px; background:#FFF; border-radius:100px;} .base3{height:200px; width:200px; margin:100px; background:#FFF; border-radius:100px;} .swiper-slide-active .ani1{animation:do1 1s ease-in forwards infinite;} @keyframes do1{ 0%{transform:scale(1);} 100%{transform:scale(1.5);} } .swiper-slide-active .ani2{animation:do2 1s ease-in forwards infinite;} @keyframes do2{ 0%{transform:scale(1); opacity:1;} 100%{transform:scale(1.5); opacity:0.2;} } .swiper-slide-active .ani3{animation:do3 1s ease-in forwards infinite;} @keyframes do3{ 0%{background:#FFF;} 100%{ background:#699;} } </style> </head> <body> <div> <div> <div class="swiper-slide ping1"> <p>第一屏</p> <div class="ani1 base1">我是动画1</div> </div> <div class="swiper-slide ping2"> <p>第二屏</p> <div class="ani2 base2">我是动画2</div> </div> <div class="swiper-slide ping3"> <p>第三屏</p> <div class="ani3 base3">我是动画3</div> </div> </div> <div></div> </div> <script src="js/jquery-1.10.1.min.js"></script> <script src="js/idangerous.swiper-2.1.min.js"></script> <script> var mySwiper = new Swiper('.swiper-container',{ mode: 'vertical', //loop: true, pagination: '.pagination', paginationClickable: true, resistance: false, speed: 0.1, onSlideChangeEnd : function(swiper){ //mySwiper.activeLoopIndex //mySwiper.activeIndex==0){ } }); </script> </body> </html>
我只做了最简单处理,动画那么神奇,全靠思维,看见swiper.js的效果,只要花时间去处理,用这个逻辑也是很简单就能实现的
<link rel="stylesheet" href="css/idangerous.swiper.css">
<script src="js/idangerous.swiper-2.1.min.js"></script>
