Javascript 未在Chrome上调用IndexedDB.open回调

我正在尝试使用IndexedDB，一切都很好，直到几个小时前，我的.open（）回调停止在Chrome上调用（在Safari上测试，效果很好）

我查看了Chrome开发者工具IndexedDB，但什么都没有

有人知道发生了什么吗

多谢各位

编辑：完全重新启动浏览器成功了，但我仍然很想知道发生了什么。

您是否在同一时间尝试删除数据库？如果存在被阻止的挂起的deleteDatabase操作，IndexedDB可能会进入一种奇怪的（尽管根据规范是正确的）状态。例如，下面的代码。如果其他都失败了，你可以检查一下chrome://indexeddb-internals，它将告诉您是否有任何挂起的打开或删除操作正在把事情搞砸

var request = indexedDB.open("test", 1);
request.onblocked = function(e) {
  console.log("DB open blocked", e);
};

request.onerror = function(err) {
  console.log("DB open error", err);
};

request.onupgradeneeded = function(e) {
  console.log("DB open upgrade needed");
};

request.onsuccess = function(e) {
  db = request.result;
  console.log("DB open success");
  db.onversionchange = function(e) {
    console.log("DB got a versionchange event")
  }
  request = indexedDB.deleteDatabase("test");
  request.onsuccess = function(e) {
    console.log("delete success will not be called")
  }
  request.onblocked = function(e) {
    console.log("delete was blocked");
    request = indexedDB.open("test", 1);
    request.onsuccess = function(e) {
      console.log("success won't be called");
    };
    request.onblocked = function(e) {
      console.log("blocked won't be called", e);
    };
    request.onerror = function(err) {
      console.log("error won't be called", err);
    };
    request.onupgradeneeded = function(e) {
      console.log("upgradeneeded won't be called");
    };
  };
};

不，我没有删除数据库，但我估计有未决的请求。谢谢你的回答。

var request = indexedDB.open("test", 1);
request.onblocked = function(e) {
  console.log("DB open blocked", e);
};

request.onerror = function(err) {
  console.log("DB open error", err);
};

request.onupgradeneeded = function(e) {
  console.log("DB open upgrade needed");
};

request.onsuccess = function(e) {
  db = request.result;
  console.log("DB open success");
  db.onversionchange = function(e) {
    console.log("DB got a versionchange event")
  }
  request = indexedDB.deleteDatabase("test");
  request.onsuccess = function(e) {
    console.log("delete success will not be called")
  }
  request.onblocked = function(e) {
    console.log("delete was blocked");
    request = indexedDB.open("test", 1);
    request.onsuccess = function(e) {
      console.log("success won't be called");
    };
    request.onblocked = function(e) {
      console.log("blocked won't be called", e);
    };
    request.onerror = function(err) {
      console.log("error won't be called", err);
    };
    request.onupgradeneeded = function(e) {
      console.log("upgradeneeded won't be called");
    };
  };
};
