最近项目中有这样一个需求，研究了两种写法一个原生，一个使用框架css

原生写法：html

<!DOCTYPE html>
<html>

    <head>
        <meta charset="UTF-8">
        <title></title>
            <link rel="stylesheet" href="css/huapin.css" />
    <!--        <link rel="stylesheet" href="css/swiper.min.css" />-->
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
    </head>

    <body>
        <div class="page2">
            <div class="silder_bg">
                <span>滑动滑动</span>
                <!--滑动的白点-->
                <img src="images/1closeLight.png" class="p2_bg1" /> //充当一个提示过分的效果
                <!--手滑动关闭图-->
                <img src="images/2closeBar.png" id='silder' class="p2_bg2"/>
            </div>
        </div>
        <div class="page3">
               
        </div>
    </body>
    <script src="js/zepto.js"></script>
    <script>
        document.getElementById('silder').addEventListener('touchmove',function(event){ //使用touchmove监听滑动
            event.preventDefault();
            var el = event.target;
            var touch = event.touches[0];
            var  curX = touch.pageX - this.offsetLeft - 73;

            if(curX <= 0) return;
            if(curX > 224){
                //符合条件须要执行的事件
                $(".page2").hide();
                $(".page3").show();
                setTimeout(function(){
                    p2show()
                },2000);
            }
            el.style.webkitTransform = 'translateX(' + curX + 'px)';//使其在x轴位移
        },false);

        document.getElementById('silder').addEventListener('touchend', function(event) {  //使用touchend监听滑动结束
            this.style.webkitTransition = '-webkit-transform 0.3s ease-in';
            this.addEventListener( 'webkitTransitionEnd', function( event ) { this.style.webkitTransition = 'none'; }, false );
            this.style.webkitTransform = 'translateX(0px)';
        }, false);
    </script>

</html>

huapin.css:

*{
    border: 0;
    margin: 0;
    overflow: hidden;
}
html,body{
    width: 100%;
    height: 100%;
}
.page2{
    
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

.page2>.bg2{
    position: fixed;
    top: 0;
    left: 0;
    height: 100vh;
    width: 100vw;
    background-color: #000000;
    opacity: 0.6;

}
.silder_bg{
    width: 78vw;
    height: 10vh;
    position: absolute;
    top:5vh;
    left: 0;
    right: 0;
    margin: 0 auto;
    z-index:200;
    background-color: #F2F2F2;
    border-radius: 6vh;

}

.p2_bg1{
    width: 10vh;
    height: 10vh;
    position: absolute;
    top:0;
    left: 20vw;
    right: 0;
    z-index:400;
    animation: light 3s linear infinite;
    -webkit-animation:light 3s linear infinite;
}
/*滑动css3动画*/
@keyframes light{
    from{left:12vw;}
    to{left:60vw ;}
}
@-webkit-keyframes light{
    from{left:10vw;opacity: 0.4;}
    to{left:55vw ;opacity: 0.4;}
}


.p2_bg2{
    width: 10vh;
    height: 10vh;
    position: absolute;
    top:0;
    left: 0;
    right: 0;
    z-index:200;

}
.silder_bg span{
    width: 78vw;
    height: 5vh;
    position: absolute;
    top:3vh;
    left: 4vw;
    right: 0;

    z-index:200;
    font-family: "微软雅黑";
    font-size:14px ;
    text-align: center;
}

以上是原生的写法，还能够使用jq的拖拽（draggable）这个方法css3

下面说下使用swiper的写法web

<!doctype html>
<html lang="en">

    <head>
        <meta charset="UTF-8">
        <title>Swiper Playground</title>
        <link rel="stylesheet" href="css/swiper.min.css">
        <link rel="stylesheet" href="css/huapin.css" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
        <style>
            html,
            body {
                position: relative;
                height: 100%;
            }
            
            body {
                font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
                font-size: 14px;
                color: #000;
                margin: 0;
                padding: 0;
            }
            
            .swiper-container {
                width: 100%;
                height: 100%;
                z-index: 300;
            }
            
            img {
                width: 100%;
            }
            
            .swiper-slide {
                z-index: 300;
            }
            
            .p2_bg {
                width: 10vh;
                height: 10vh;
                z-index: 300;
            }
        </style>
    </head>

    <body>
    //html布局同上面，只是加了个swiper-container容器
        <div class="silder_bg">
            <span>滑动滑动</span>
            <!--滑动的白点-->
            <img src="images/1closeLight.png" class="p2_bg1" />
            <!--手滑动关闭图-->
            <div class="swiper-container">
                <div class="swiper-wrapper">
                    <div class="swiper-slide">  //去掉swiper.min.css对swiper-slide的默认样式
                        <img src="images/2closeBar.png" class="p2_bg" />
                    </div>

                </div>
            </div>
        </div>
        <script src="js/zpto.js"></script>
        <script src="js/swiper.min.js"></script>
        <script>
         简单思路：滑动swiper时监听滑动距离判断条件便可
            var swiper = new Swiper('.swiper-container', {
                slidesPerView: 'auto',
                freeMode: true,
                on: {
                    touchMove: function() {
                        //     alert(swiper.translate)
                        if(swiper.translate > 130) {
                            $(".silder_bg").fadeOut(500)
                        }
                    },
                },
            });
        </script>
    </body>

</html>

以上两种写法，原生的实现起来互动的更加快速，swiper滑动的相对有弹性一点，所要监听的距离更短，也可实现效果api

1. swiper实现触摸滑动
2. swiper实现左右滑动案例
3. Swiper 滑动
4. 实现图片滑动解锁
5. 滑动解锁
6. swiper 滑动插件
7. swiper禁止滑动
8. swiper手动滑动后失效解决
9. swiper禁止手动滑动
10. 微信小程序 swiper滑动出现无限滑动bug
