容器外的 Swiper 导航按钮

Question

我试图在 swiper 容器外显示导航按钮，因为容器溢出：隐藏我不得不创建一个带有位置的包装：相对并绝对定位按钮。

那行得通，问题是现在导航按钮控制所有滑块，我想不出解决这个问题的方法。

如果滑块与不同的内容相同，我不想用不同的类初始化多个滑块。

JSFiddle

var sliderProdutosDestaque = new Swiper('.slider-produtos-destaque.swiper-container', {
  slidesPerView: 2,
  spaceBetween: 10,
  navigation: {
    nextEl: '.swiper-next',
    prevEl: '.swiper-prev',
  }
});

body {
  padding: 20px 60px 40px;
}

.slider-produtos-wrap {
  position: relative;
  width: 100%;
  margin-top: 20px;
}

.swiper-slide {
  z-index: 1;
  height: 150px;
  background: blue;
}

.swiper-prev,
.swiper-next {
  width: 60px;
  height: 60px;
  background: red;
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  border-radius: 60px;
  z-index: 9999;
}

.swiper-prev {
  left: -30px;
}

.swiper-next {
  right: -30px;
}

简单、小巧、整洁。

document.querySelectorAll('.swiper-container').forEach(function(elem) {
  new Swiper(elem, {
    slidesPerView: 2,
    spaceBetween: 10,
    navigation: {
      nextEl: elem.nextElementSibling.nextElementSibling,
      prevEl: elem.nextElementSibling,
    }
  });
});

body {
  padding: 20px 60px 40px;
}

.slider-produtos-wrap {
  position: relative;
  width: 100%;
  margin-top: 20px;
}

.swiper-slide {
  z-index: 1;
  height: 150px;
  background: blue;
}

.swiper-prev,
.swiper-next {
  width: 60px;
  height: 60px;
  background: red;
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  border-radius: 60px;
  z-index: 9999;
}

.swiper-prev {
  left: -30px;
}

.swiper-next {
  right: -30px;
}

<div class="slider-produtos-wrap">

    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
      <div class="swiper-slide">Slide 2</div>
      <div class="swiper-slide">Slide 3</div>
    </div>
  </div>

  <div class="swiper-prev"></div>
  <div class="swiper-next"></div>

</div>

<div class="slider-produtos-wrap">
  <div class="slider-produtos-destaque swiper-container">
    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
      <div class="swiper-slide">Slide 2</div>
      <div class="swiper-slide">Slide 3</div>
    </div>
  </div>

  <div class="swiper-prev"></div>
  <div class="swiper-next"></div>

</div>

一种可能的解决方案是循环遍历包含滑块容器的元素，然后获取所需的元素（Swiper、Next Btn、Prev Btn）并在 Swiper 的设置中使用它。

var x = document.getElementsByClassName("slider-produtos-wrap");

for(var i = 0; i < x.length; i++) {

    var el = x[i];

  var swiper = el.getElementsByClassName("swiper-container")[0];
  var nx = el.getElementsByClassName("swiper-next")[0];
  var pr = el.getElementsByClassName("swiper-prev")[0];

  new Swiper(swiper, {
        slidesPerView: 2,  
        spaceBetween: 10,
        navigation: {
          nextEl: nx,
          prevEl: pr
        }
  });
}
