swiper 实现滑动解锁

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

原生写法：

<!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="data:images/1closeLight.png" class="p2_bg1" /> //充当一个提示过度的效果

                <!--手滑动关闭图-->

                <img src="data: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){
                //符合条件需要执行的事件

                $(".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:;

    margin:;

    overflow: hidden;

}

html,body{

    width: 100%;

    height: 100%;

}

.page2{

    position: fixed;

    top:;

    left:;

    width: 100%;

    height: 100%;

}

.page2>.bg2{

    position: fixed;

    top:;

    left:;

    height: 100vh;

    width: 100vw;

    background-color: #000000;

    opacity: 0.6;

}

.silder_bg{

    width: 78vw;

    height: 10vh;

    position: absolute;

    top:5vh;

    left:;

    right:;

    margin: 0 auto;

    z-index:;

    background-color: #F2F2F2;

    border-radius: 6vh;

}

.p2_bg1{

    width: 10vh;

    height: 10vh;

    position: absolute;

    top:;

    left: 20vw;

    right:;

    z-index:;

    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:;

    left:;

    right:;

    z-index:;

}

.silder_bg span{

    width: 78vw;

    height: 5vh;

    position: absolute;

    top:3vh;

    left: 4vw;

    right:;

    z-index:;

    font-family: "微软雅黑";

    font-size:14px ;

    text-align: center;

}

以上是原生的写法，还可以使用jq的拖拽（draggable）这个方法

下面说下使用swiper的写法

<!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="data: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="data: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即可

            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
