为运行在chrome中的tensorflow js解决“未捕获(在promise中) TypeError: fs.writeFile不是一个函数”的替代方法

const content = "Hello, World!";
const blob = new Blob([content], { type: "text/plain" });

// 创建一个下载链接
const downloadLink = document.createElement("a");
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = "file.txt";

// 模拟点击下载链接
downloadLink.click();

const content = "Hello, World!";

// 打开或创建数据库
const request = indexedDB.open("myDatabase", 1);

request.onerror = function(event) {
  console.log("数据库打开/创建失败");
};

request.onsuccess = function(event) {
  const db = event.target.result;

  // 创建一个事务
  const transaction = db.transaction(["files"], "readwrite");

  // 获取存储对象
  const filesStore = transaction.objectStore("files");

  // 将内容保存到数据库
  const saveRequest = filesStore.put(content, "file.txt");

  saveRequest.onsuccess = function(event) {
    console.log("文件保存成功");
  };

  saveRequest.onerror = function(event) {
    console.log("文件保存失败");
  };
};

request.onupgradeneeded = function(event) {
  const db = event.target.result;

  // 创建存储对象
  const filesStore = db.createObjectStore("files");

  // 创建索引
  filesStore.createIndex("name", "name", { unique: true });
};
