vue-awesome-swiper 组件内设置样式失效问题


给外框定义id

<swiper class="swiper" id="pa" :options="swiperOption"  ref="mySwiper">
    <!-- slides -->
    <swiper-slide style="background: #007aff"> I'm slide 1</swiper-slide>
    <swiper-slide style="background: yellow"> I'm slide 2</swiper-slide>
    <swiper-slide style="background: red"> I'm slide 3</swiper-slide>
    <swiper-slide style="background: green"> I'm slide 4</swiper-slide>
    <!-- Optional controls -->
    <div class="swiper-pagination" slot="pagination"></div>
  </swiper>

方法一:全局覆盖

  • 单独新建css文件,在index.html引入
  • 在组件内书写 不要加scoped
<style>
  .swiper {
    width: 100%;
    height: 600px;
  }

  swiper-slide {
    width: 100%;
    height: 600px;
  }

  .swiper-pagination-bullet {
    width: 20px;
    height: 20px;
    text-align: center;
    line-height: 20px;
    font-size: 12px;
    color:#000;
    opacity: 1;
    background: rgba(0,0,0,0.2);
  }
  .swiper-pagination-bullet-active {
    color:#fff;
    background: #ff51d6;
  }

注:如果存在优先级问题 添加 !important提升指定样式规则的应用优先权 例如:

<style>
    .swiper-pagination-bullet-active {
        color: #fff !important}
</style>

方法二:局部样式限定

用该组件最外层class包裹内部轮播样式,不加scoped

<style css="less">
.swiper{
    .swiper-pagination-bullet-active {
        color: #fff}
}
</style>

方法三:样式穿透(推荐)

/deep/ 是sass和less的样式穿透
#pa /deep/ .swiper-pagination-bullet {
    width: 20px;
    height: 20px;
    text-align: center;
    line-height: 20px;
    font-size: 12px;
    color:#000;
    opacity: 1;
    background: rgba(0,0,0,0.2);
  }
  #pa /deep/ .swiper-pagination-bullet-active {
    color:#fff;
    background: #ff51d6;
  }
>>>是stylus的样式穿透
#pa >>> .swiper-pagination-bullet {
    width: 20px;
    height: 20px;
    text-align: center;
    line-height: 20px;
    font-size: 12px;
    color:#000;
    opacity: 1;
    background: rgba(0,0,0,0.2);
  }
  #pa >>> .swiper-pagination-bullet-active {
    color:#fff;
    background: #ff51d6;
  }

<script>
  import {swiper, swiperSlide} from 'vue-awesome-swiper'
  import 'swiper/dist/css/swiper.css'

  export default {
    name: 'carrousel',
    data() {
      return {
        swiperOption: {
          // spaceBetween: 30, //板块间距
          loop: true, //无缝轮播
          centeredSlides: true,
          autoplay: {  //自动轮播

            paginationType: 'custom',
          }
        }
      }
    },
    components: {
      swiper,
      swiperSlide
    },
    // 如果你需要得到当前的swiper对象来做一些事情,你可以像下面这样定义一个方法属性来获取当前的swiper对象,同时notNextTick必须为true
    computed: {
      swiper() {
        // console.log(this.$refs.mySwiper.swiper);
        return this.$refs.mySwiper.swiper
      }
    },
    mounted() {
      // 然后你就可以使用当前上下文内的swiper对象去做你想做的事了
      console.log('this is current swiper instance object', this.swiper);
      // this.swiper.slideTo(3, 1000, false)
      console.log('mounted');
      //鼠标覆盖停止自动切换
      this.swiper.el.onmouseover = function () {
        this.swiper.autoplay.stop();
      };
      //鼠标离开开始自动切换
      this.swiper.el.onmouseout = function () {
        this.swiper.autoplay.start();
      };
    }
  }
</script>
<style scoped>
  .swiper {
    width: 100%;
    height: 600px;
  }

  swiper-slide {
    width: 100%;
    height: 600px;
  }

  #pa /deep/ .swiper-pagination-bullet {
