在Javascript中导出的csv文件中创建下拉菜单

var dropdownOptions = ["选项1", "选项2", "选项3"];

var csvRow = dropdownOptions.join(",") + "\n";

var dropdownOptions = ["选项1", "选项2", "选项3"];

// 创建csv文件内容
var csvContent = "下拉菜单\n"; // csv文件的标题行
for (var i = 0; i < data.length; i++) {
  var dropdownIndex = i % dropdownOptions.length; // 获取下拉菜单选项的索引值
  var csvRow = dropdownOptions[dropdownIndex] + "\n"; // 将下拉菜单选项添加到csv文件的一行中
  csvContent += csvRow; // 添加到csv文件内容中
}

// 导出csv文件
var csvData = new Blob([csvContent], { type: "text/csv;charset=utf-8;" });
var csvURL = URL.createObjectURL(csvData);
var link = document.createElement("a");
link.href = csvURL;
link.download = "data.csv";
link.click();
