Swiper nav buttons outside container

问题

I'm trying to display the nav buttons outside the swiper container, because of the container overflow: hidden i had to create a wrap with position: relative and position the buttons absolutely.

That worked, the problem is that now the nav buttons control all sliders and i can't figure out a way to solve this.

I don't want to initialize multiple sliders with different classes if the slider is the same with different content.

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;
}

A possible solution is to loop through the elements that contain the slider container, and then grabbing the elements that are required (Swiper, Next Btn, Prev Btn) and using this in the setup for the Swiper.

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
        }
  });
}

Easy, tiny and tidy.

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;
}

Another way for anyone that might find it useful. Pass in count as a props with a different value for each slider. I did count="1" and count="2". This gives each sliders navigation arrows a different class so they will work independently of each other

<div :class="'swiper-button-prev-' + count" slot="button-prev"></div>
<div :class="'swiper-button-next-' + count" slot="button-next"></div>

props: ['count'],
data() {
  return {
    swiperOption: {
    slidesPerView: 'auto',
    spaceBetween: 45,
    grabCursor: true,
    centerInsufficientSlides: true,
    navigation: {
      nextEl: `.swiper-button-next-${this.count}`,
      prevEl: `.swiper-button-prev-${this.count}`
    }
  }
}

.swiper-container {
    width: 100%;
    height: 400px;
    padding: 0 50px;
}
.swiper-container::before{
    content: "";
    display: block;
    background: #fff;
    left: 0;
    position: absolute;
    top: 0;
    height: 400px;
    width: 40px;
    z-index: 9;
}
.swiper-container::after{
    content: "";
    display: block;
    background: #fff;
    right: 0;
    position: absolute;
    top: 0;
    height: 400px;
    width: 40px;
    z-index: 9;
}
