js下载篇

1、地址下载

// 地址下载,fileName暂无作用
export const urlDownload = (url, fileName = '下载文件') => {
  // 创建隐藏的可下载链接
  let eleLink = document.createElement('a')
  eleLink.download = fileName
  eleLink.style.display = 'none'
  eleLink.href = url
  // 触发点击
  document.body.appendChild(eleLink)
  eleLink.click()
  // 然后移除
  document.body.removeChild(eleLink)
}

2、转化text下载

// 内容转化为文件下载
export const fileDownload = (file, fileName = '下载文件') => {
  // 创建隐藏的可下载链接
  let eleLink = document.createElement('a')
  eleLink.download = fileName
  eleLink.style.display = 'none'
  // 字符内容转变成blob地址
  let blob = new Blob([file])
  eleLink.href = URL.createObjectURL(blob)
  // 触发点击
  document.body.appendChild(eleLink)
  eleLink.click()
  // 然后移除
  document.body.removeChild(eleLink)
}
