如何利用vue展示.docx文件、excel文件和csv文件内容

npm install --save mammoth

import mammoth from "mammoth"

<div style="height:850px;overflow-y:auto;" v-html="content"/>

//根据文件url，以arraybuffer的形式获取docx文件内容，传给插件转成html格式，展示在页面上
var xhr = new XMLHttpRequest()
xhr.open('GET', fileurl, true)
xhr.responseType = 'arraybuffer'
const rhis = this
xhr.onload = function(){
  if(xhr.status === 200){
    mammoth.convertToHtml({arrayBuffer: new Uint8Array(xhr.response)}).then(function(res){
	  rhis.$nextTick(()=>{
	    rhis.content = res.value
	  })
    })
  }
}
xhr.send()
