idangero.us swiper - “未定义 Swiper”错误

Question

I've recently tried to set up a "idangero.us Swiper" feature on my site. Unfortunately, it doesn't seem to be working. My experience with JS is very limited so I'm at a complete loss on how to fix this.

The error I receive is Uncaught ReferenceError: Swiper is not defined

Thank you for any help you can give. http://www.hollywoodfeed.com/pages/catalog-page-1

My HTML is

<!-- Swiper -->
<style>
.swiper-container{
width:100%;
height:auto;
margin:20px auto;
}
.swiper-slide{     
text-align:center;
font-size:18px;
background:#fff;
line-height:300px;
}
</style>

<div class="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 class="swiper-slide">Slide 4</div>
<div class="swiper-slide">Slide 5</div>
<div class="swiper-slide">Slide 6</div>
<div class="swiper-slide">Slide 7</div>
<div class="swiper-slide">Slide 8</div>
<div class="swiper-slide">Slide 9</div>
<div class="swiper-slide">Slide 10</div>
</div>

<div class="swiper-pagination"></div>

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

JS

<!-- Swiper Include Files -->
<script>  {{ 'swiper.min.js' | asset_url }}</script>

<script>
  var swiper;
  $(document).ready(function () {
var swiper = new Swiper('.swiper-container', {
    nextButton: '.swiper-button-next',
    prevButton: '.swiper-button-prev',
    pagination: '.swiper-pagination',
    paginationType: 'fraction'
})
});
</script>

Answer 1

It looks to me that whatever templating system you are using isn't putting the dependency script file on the page.

<!-- Swiper Include Files -->
<script>  {{ 'swiper.min.js' | asset_url }}</script>

The above script outputs the below:

<script>     
  //cdn.shopify.com/s/files/1/0659/4529/t/75/assets/swiper.min.js?10728068994914913511
</script>

The reference to the script file shouldn't be inside the script element itself. Instead it should be in the script tags src attribute. Like so:

<script src="//cdn.shopify.com/s/files/1/0659/4529/t/75/assets/swiper.min.js?10728068994914913511">
</script>

tl;dr

The swiper dependencies were missing. You need to include them properly.

即使您没有将链接 swiper.js 文件的脚本标记放在 head 部分的顶部，您也会收到此错误。
