pdf地址展示成Swiper轮播方式-复制链接

1、安装vue-pdf插件，swiper插件、clipboard

npm install vue-pdf -s
npm install swiper -S
npm install clipborad -S

2、使用，标题头提取的组件，slot占位

<template>
    <div class="pagepdf">
        <page-title :headerSetting="headerSetting">
          
          <div slot="header_left" class="header_ico">
            <img class="goBackIcon" :src="goBackIcon" alt="" />
          div>
          <div slot="header_center">pdfdiv>
          
          <div slot="header_right" class="header_right copyDom" @click="copy(url)">
              复制连接
          div>
        page-title>

        <div class="tools" v-show="lists.length>0">
            <div class="swiper-button-prev mr10">上一页div>
            <div class="page">{{currentId}}/{{pageTotalNum}} div>
            <div class="swiper-button-next mr10">下一页div>
        div>
        <div class="">
            <div id="tabApp1" class="swiper-container" style="visibility: hidden;">
                <div class="swiper-wrapper" ref="swiperWrapper0">
                    <div class="swiper-slide" v-for="(item, index) in lists" :class="{ active: currentId == item.id }"
                        :key="index">

        div>
        <div id="tabContain" class="tabContain swiper-container" v-show="lists.length>0">
            <div class="swiper-wrapper">
