<script>
import Pdfh5 from "pdfh5";
import "pdfh5/css/pdfh5.css";
import { baseURL } from "@/config";

export default {
  name: "basic-info",
  data() {
    return {
      imgList: "", //
      navTitle: "",
      pdfh5: null,
      show: false,
      index: 0,
    };
  },
  created() {
    this.init();
  },
  mounted() {
    this.initPdf();
  },
  methods: {
    init() {
      let { name } = this.$route.query;
      this.navTitle = name;
    },
    initPdf() {
      this.pdfh5 = new Pdfh5("#pdf", {
        pdfurl: baseURL,
        goto: 1, // 回到顶部
      });
       // 允许pdf滚动
      this.pdfh5.scrollEnable(true);
      // 请求成功的回调
      this.pdfh5.on("success", () => {
        const list = [];
        // 通过 document.images 获取所有HTML图片元素的集合,并将HTMLCollection格式(HTML元素的集合)转换成普通数组
        const imageList = Array.prototype.slice.call(document.images)
        imageList .forEach((el) => {
          list.push(el.currentSrc);
        });
        this.imgList= list;
      });
    },
    goBack() {
      this.$router.go(-1);
    },
    clickImg() {
      this.show = true;
    },
    onChange(index) {
