PPT组件二

1.在pptx.js官网下载压缩包
pptx
（2）选择版本下载

2.在public文件夹中添加pptxjs依赖文件
3.在index.html中引入

    <link rel="stylesheet" href="/PPTXjs/css/pptxjs.css" />
 
    <link rel="stylesheet" href="/PPTXjs/css/nv.d3.min.css" />
    <!-- for charts graphs -->
 
    <script
      type="text/javascript"
      src="/PPTXjs/js/jquery-1.11.3.min.js"
    ></script>
 
    <script type="text/javascript" src="/PPTXjs/js/jszip.min.js"></script>
    <!-- v2.. , NOT v.3.. -->
 
    <script type="text/javascript" src="/PPTXjs/js/filereader.js"></script>
    <!--https://github.com/meshesha/filereader.js -->
 
    <script type="text/javascript" src="/PPTXjs/js/d3.min.js"></script>
    <!-- for charts graphs -->
 
    <script type="text/javascript" src="/PPTXjs/js/nv.d3.min.js"></script>
    <!-- for charts graphs -->
 
    <script type="text/javascript" src="/PPTXjs/js/pptxjs.js"></script>
 
    <script type="text/javascript" src="/PPTXjs/js/divs2slides.js"></script>
    <!-- for slide show -->

4.在页面中使用

<template>
  <div id="pptx"></div>
</template>

<script>
export default {
  name: 'PptView',
  mounted() {
    this.pptxShow(this.src);
  },
  methods: {
    pptxShow(src) {
      this.$nextTick(() => {
        $("#pptx").pptxToHtml({
          pptxFileUrl: src,
          slidesScale: "100%",
        });
      });
    },
  },
  props: {
    src: {
      type: String,
      required: true,
    },
  },
}
</script>

<style scoped>

</style>
