Blob 在生成 csv 文件时跳过第一列

Question

我正在尝试使用 blob 类生成 CSV 文件。第一行工作正常，但其余行正在跳过第一列var ExcelIndex = ['"user_name","user_hash","authenticate_id","first_name","last_name","description","department","phone_home","phone_mobile","phone_work","phone_other","phone_fax","address_street","address_city","address_state","address_country","address_postalcode","Errors"'];var dataInSingleStringArray = new Array();dataInSingleStringArray.push(ExcelIndex[0], "\n");var ExcelInde = ['"user_name","user_hash","authenticate_id","first_name","last_name","description","department","phone_home","phone_mobile","phone_work","phone_other","phone_fax","address_street","address_city","address_state","address_country","address_postalcode","Errors"'];// var dataInSingleStringArray = new Array();dataInSingleStringArray.push(ExcelInde[0], "\n");window.URL = window.webkitURL || window.URL;var contentType = 'text/csv';var csvFile = new Blob([dataInSingleStringArray], {type: contentType});var a = document.createElement('a');a.setAttribute("style", "margin-left: 700px;font-size: 2em;")a.download = 'failed_data.csv';a.href = window.URL.createObjectURL(csvFile);a.textContent = 'Download File';document.getElementById('link').appendChild(a);<div id="link"></div>

不要每次向数组添加数据时都添加“\n”，而是将数据添加到数组，然后用“\n”将其连接起来

      var ExcelIndex = ['"user_name","user_hash","authenticate_id","first_name","last_name","description","department","phone_home","phone_mobile","phone_work","phone_other","phone_fax","address_street","address_city","address_state","address_country","address_postalcode","Errors"'];

      var dataInSingleStringArray = new Array();

      dataInSingleStringArray.push(ExcelIndex[0]);

      var ExcelInde = ['"user_name","user_hash","authenticate_id","first_name","last_name","description","department","phone_home","phone_mobile","phone_work","phone_other","phone_fax","address_street","address_city","address_state","address_country","address_postalcode","Errors"'];

      // var dataInSingleStringArray = new Array();

      dataInSingleStringArray.push(ExcelInde[0]);

      //console.log(dataInSingleStringArray);

      //console.log(dataInSingleStringArray.join("\r\n"));

      window.URL = window.webkitURL || window.URL;

      var contentType = 'text/csv';

      var csvFile = new Blob([dataInSingleStringArray.join("\n")], {type: contentType});

      var a = document.createElement('a');

      a.setAttribute("style", "margin-left: 700px;font-size: 2em;")

      a.download = 'failed_data.csv';

      a.href = window.URL.createObjectURL(csvFile);

      a.textContent = 'Download File';

      document.getElementById('link').appendChild(a);
