如何将含有逗号的html表格数据导出为.csv文件？

function exportToCSV() {
  var table = document.getElementById("myTable");
  var csvString = "";

  for (var i = 0; i < table.rows.length; i++) {
    var rowData = table.rows[i].cells;

    for (var j = 0; j < rowData.length; j++) {
      var cellData = rowData[j].innerText;
      
      // 处理包含逗号的数据
      if (cellData.includes(",")) {
        cellData = "\"" + cellData + "\"";
      }
      
      // 添加数据到CSV字符串
      csvString += cellData;

      // 添加逗号作为字段分隔符
      if (j < rowData.length - 1) {
        csvString += ",";
      }
    }

    // 添加换行符作为行分隔符
    csvString += "\n";
  }

  // 保存CSV字符串为.csv文件
  var blob = new Blob([csvString], { type: "text/csv;charset=utf-8;" });
  var link = document.createElement("a");
  if (link.download !== undefined) {
    var url = URL.createObjectURL(blob);
    link.setAttribute("href", url);
    link.setAttribute("download", "table.csv");
    link.style.visibility = "hidden";
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
  }
}
