如何打开indexeddb数据库？

var request = indexedDB.open("myDatabase", 1);

request.onupgradeneeded = function(event) {
  var db = event.target.result;
  var objectStore = db.createObjectStore("myObjectStore", { keyPath: "id" });
  objectStore.createIndex("name", "name", { unique: false });
};

request.onsuccess = function(event) {
  var db = event.target.result;
  // 执行数据库操作
};

var request = indexedDB.open("myDatabase", 1);

request.onupgradeneeded = function(event) {
  var db = event.target.result;
  var objectStore = db.createObjectStore("myObjectStore", { keyPath: "id" });
  objectStore.createIndex("name", "name", { unique: false });
};

request.onsuccess = function(event) {
  var db = event.target.result;
  // 执行数据库操作
};

request.onerror = function(event) {
  console.log("打开数据库失败");
};
