关于javascript:js导出文件

总结了自己工作中罕用的三种导出文件的形式

• 后端返回的单个链接下载

function download(url, filename) {  let link = document.createElement("a")  link.style.display = "none"  link.href = `${url}`  link.setAttribute("download", `${filename}`)  document.body.appendChild(link)  link.click()  document.body.removeChild(link)  link = null}

• 后端返回多个链接，批量下载

function batchDownload(data) {  data.forEach(item => {    download(item.filePath, item.fileName)  })}

• 后端返回一个流文件

function downloadFileStream(name = "1", content, suffix = "doc") {  //文件流文件下载  const blob = new Blob([content])  const fileName = `${name}.${suffix}`  const elink = document.createElement("a")  elink.download = fileName  elink.style.display = "none"  elink.href = URL.createObjectURL(blob)  document.body.appendChild(elink)  elink.click()  URL.revokeObjectURL(elink.href) // 开释URL 对象  document.body.removeChild(elink)}
