介绍 ​

常用于一组图片或卡片轮播。

基础用法 ​

auto-play 自动轮播的时长 init-page 初始索引值 pagination-visible 是否显示分页指示器 pagination-color 指示器颜色自定义

html
<template>
  <nut-swiper :init-page="page" :pagination-visible="true" pagination-color="#426543" pagination-unselected-color="#808080" auto-play="3000">
    <nut-swiper-item>
      <img src="https://storage.360buyimg.com/jdc-article/NutUItaro34.jpg" alt="" />
    </nut-swiper-item>
    <nut-swiper-item>
      <img src="https://storage.360buyimg.com/jdc-article/NutUItaro2.jpg" alt="" />
    </nut-swiper-item>
    <nut-swiper-item>
      <img src="https://storage.360buyimg.com/jdc-article/welcomenutui.jpg" alt="" />
    </nut-swiper-item>
    <nut-swiper-item>
      <img src="https://storage.360buyimg.com/jdc-article/fristfabu.jpg" alt="" />
    </nut-swiper-item>
  </nut-swiper>
</template>
<script lang="ts">
  import { reactive, toRefs } from 'vue';
  export default {
    setup() {
      const state = reactive({
        page: 2,
      });
      return { ...toRefs(state) };
    }
  };
</script>
<style lang="scss">
  .nut-swiper-item {
    line-height: 150px;
    img {
      width: 100%;
      height: 100%;
    }
  }
</style>

异步加载 ​
