我正在尝试获取此 Flickity 示例（CodePen）在 VueJS 组件中工作。

HTML

<div class="carousel">
  <div class="carousel-cell"></div>
  <div class="carousel-cell"></div>
  <div class="carousel-cell"></div>
  <div class="carousel-cell"></div>
  <div class="carousel-cell"></div>
</div>

JS

 var flkty = new Flickity('.carousel');

    flkty.on( 'dragStart', function() {
      console.log('dragStart');
    });

我收到此错误：

Flickity 的坏元素：轮播

我的不工作的版本：

JS数据()

import Flickity from 'flickity'
var flkty = new Flickity('.carousel')
export default {
  data () {
    return {
      flickityOptions: {
        dragThreshold: 50,
        initialIndex: 1,
        prevNextButtons: false,
        pageDots: false,
        wrapAround: false,
        hash: true,
        percentPosition: false
      },

JS挂载()

  mounted () {
    flkty.on('dragStart', function () {
      this.stageDragging = true
      console.log('stageDragging: ' + this.stageDragging)
    })
    flkty.on('dragEnd', function () {
      this.stageDragging = false
      console.log('stageDragging: ' + this.stageDragging)
    })

如何在 VueJS 组件中使用这个 Flickity 示例 ？

在您的部分中，JavaScript 在模板在文档中呈现之前执行，因此如果在挂钩之外调用<script>，Flickity 将无法找到。.carouselVue 实例有一个mounted()生命周期钩子，它在其模板渲染时被调用，你应该在这里创建 Flickity 轮播：

// const flkty = new Flickity(...) // DON'T DO THIS HERE
export default {
  mounted() {
    this.$nextTick(() => {
      const flkty = new Flickity(...)
      // ...
    });
  }
}

此外，不要将类名传递.carousel给 Flickity，而是将 a 传递ref给.carousel元素以避免.carousel在文档中抓取意外元素（例如，如果您有多个组件实例）。

// template
<div ref="carousel">

// script
new Flickity(this.$refs.carousel)

var app = new Vue({
  el: '#app',
  data() {
    return {
      options: {
        dragThreshold: 50,
        initialIndex: 1,
        prevNextButtons: false,
        pageDots: false,
        wrapAround: false,
        hash: true,
        percentPosition: false,
      },
      itemsCount: 5,
      flkty: null,
    }
  },
  mounted: function () {
    this.flkty = new Flickity(`#${this.$el.id} .carousel`);
    this.flkty.on( 'dragStart', function() {
      console.log('dragStart');
    });
  }
})

Vue.config.devtools = false;
Vue.config.productionTip = false;
* { box-sizing: border-box; }

body { font-family: sans-serif; }

.carousel {

.carousel-cell {

具体的 Rails 案例：

错误提示，因为我的 CDN 脚本标签和 JS 代码在Javascript/Packs同一时间layout.html.erb

<%= javascript_pack_tag 'flickity' %>
<script src="https://unpkg.com/flickity@2/dist/flickity.pkgd.min.js"></script>
