swiper插件在移动端，多个swiper左右滑动时有空白的问题

之前在项目上用到了多个swiper、但是结构结构代码css、以及js  几乎一样的
除了第一个swiper左右滑动有回弹、其他都没有回弹、于是尝试了各种方法都不行。

百思不得其解 ，最后在官网终于找到了解决方法、一下是代码
HTML代码

<nav>
    <div class="swiper-container" id="swiper">
        <ul class="swiper-wrapper tabTwo">
            <li class="swiper-slide curTwo active"><a href="javascript:void(0);">2019</a><p class="bord"></p></li>
            <li class="swiper-slide"><a href="javascript:void(0);">2018</a><p class="bord"></p></li>
            <li class="swiper-slide"><a href="javascript:void(0);">2017</a><p class="bord"></p></li>
            <li class="swiper-slide"><a href="javascript:void(0);">2016</a><p class="bord"></p></li>
        </ul>
    </div>
    <div class="shade"></div>
</nav>
<div class="month on">
    <div class="swiper-container">
        <ul class="swiper-wrapper tab">
            <li class="swiper-slide cur twoActive"><a href="javascript:void(0);">11</a></li>
            <li class="swiper-slide"><a href="javascript:void(0);">11</a></li>
            <li class="swiper-slide"><a href="javascript:void(0);">11</a></li>
            <li class="swiper-slide"><a href="javascript:void(0);">11</a></li>
        </ul>
    </div>
</div>

<div class="month">
    <div class="swiper-container">
        <ul class="swiper-wrapper tab">
            <li class="swiper-slide cur twoActive"><a href="javascript:void(0);">12</a></li>
            <li class="swiper-slide"><a href="javascript:void(0);">12</a></li>
            <li class="swiper-slide"><a href="javascript:void(0);">12</a></li>
            <li class="swiper-slide"><a href="javascript:void(0);">12</a></li>
        </ul>
    </div>
</div>

四五个swiper

接着JS代码：var mySwiper = new Swiper('.swiper-container', {

    autoplay: false,//可选选项，自动滑动

    slidesPerView : "auto",
    observer:true,
    observeParents:true,
});
一段js代码就可以控制全部的swiper了，因为结构什么的都一样
只需要在原本的swioer，js代码上加上 以下这两句监听swiper就行了
observer:true,
observeParents:true,
