        @loaded="loadPdfHandler"
      ></pdf>
    </div>
  </div>
</template>

3、script部分

<script>
import pdf from "vue-pdf";
import CMapReaderFactory from 'vue-pdf/src/CMapReaderFactory.js';
export default {
  data() {
    return {
      currentPage: 0, // pdf文件页码
      pageCount: 0, // pdf文件总页数,
      flag: true,
    }
  },
  components: {
    pdf,
  },
  computed: {
    path() {
      return this.$route.query.path //path是pdf的地址，我是在上个页面路由通过query传过来的，具体根据自己的情况
    },
    pdffile() {
      return pdf.createLoadingTask({
        url: this.path,
        CMapReaderFactory //这里用来解决部分pdf预览乱码问题，主要是看不到汉字的问题
      })
    }
  },
  methods: {
    loadPdfHandler (e) {
      this.currentPage = 1 // 加载的时候先加载第一页
    },
    changePdfPage (val) {
      if(!this.flag) return
      this.flag = false
      setTimeout(() => { //这里的定时器用来防止用户频繁点击，我设置的0.5秒内无论点击多少次都只触发一次
        this.flag = true
        if (val === 0 && this.currentPage > 1) {
          this.currentPage--
        }
        if (val === 1 && this.currentPage < this.pageCount) {
          this.currentPage++
        }
      }, 500)
    },
  }
}
</script>
