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" /><!-- word">for charts graphs --><scripttype="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><!-- word">for charts graphs --><script type="text/javascript" src="/PPTXjs/js/nv.d3.min.js"></script><!-- word">for charts graphs --><script type="text/javascript" src="/PPTXjs/js/pptxjs.js"></script><script type="text/javascript" src="/PPTXjs/js/divs2slides.js"></script><!-- word">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>
