vue前端导出zip包

1. npm install jszip  /npm install script-loader / npm install file-saver

2.功能代码

require('script-loader!file-saver');
import JSZip from 'jszip'

export function export_txt_to_zip(th, jsonData, txtName, zipName) {
  const zip = new JSZip()
  const txt_name = txtName || 'file'
  const zip_name = zipName || 'file'
  const data = jsonData
  let txtData = `${th}\r\n`
  data.forEach((row) => {
    let tempStr = ''
    tempStr = row.toString()
    txtData += `${tempStr}\r\n`
  })
  zip.file(`${txt_name}.txt`, txtData)
  zip.generateAsync({
    type: "blob"
  }).then((blob) => {
    saveAs(blob, `${zip_name}.zip`)
  }, (err) => {
    alert('导出失败')
  })
}

3.调用代码：

    handleDownload() {
      this.downloadLoading = true
      import('@/vendor/Export2Zip').then(zip => {
        const tHeader = ['Id', 'Title', 'Author', 'Readings', 'Date']
        const filterVal = ['id', 'title', 'author', 'pageviews', 'display_time']
        const list = this.list
        const data = this.formatJson(filterVal, list)
        zip.export_txt_to_zip(tHeader, data, this.filename, this.filename)
        this.downloadLoading = false
      })
    },
    formatJson(filterVal, jsonData) {
      return jsonData.map(v => filterVal.map(j => v[j]))
    }
