Vue exports tables ending in .xlsx

Vue exports tables ending in .xlsx

1. First, npm downloads two dependencies (file-saver xlsx)

npm install -S file-saver xlsx 

2. Import these two dependencies (file-saver xlsx) on the page that needs to export .xlsx:

import FileSaver from "file-saver";
import XLSX from "xlsx";

3.js part:

 exportExcel() {
    
    
      // 设置当前日期
      let time = new Date();
      let year = time.getFullYear();
      let month = time.getMonth() + 1;
      let day = time.getDate();
      let name = "故障信息" + year + "" + month + "" + day;
      // console.log(name)
      /* generate workbook object from table */
      //  .table要导出的是哪一个表格
      var wb = XLSX.utils.table_to_book(document.querySelector(".table"));
      /* get binary string as output */
      var wbout = XLSX.write(wb, {
    
    
        bookType: "xlsx",
        bookSST: true,
        type: "array",
      });
      try {
    
    
        //  name+'.xlsx'表示导出的excel表格名字
        FileSaver.saveAs(
          new Blob([wbout], {
    
     type: "application/octet-stream" }),
          name + ".xlsx"
        );
      } catch (e) {
    
    
        if (typeof console !== "undefined") console.log(e, wbout);
      }
      return wbout;
    },
