deleteObjectStore() 方法在 IDBDatabase interface destroys the object store with the given name in the connected database, along with any indexes that reference it.

就像 IDBDatabase.createObjectStore , this method can be called only 在 versionchange transaction.

注意： 此特征可用于 Web 工作者 .

句法

dbInstance.deleteObjectStore(name);
					

参数

名称

The name of the object store you want to delete.

异常

此方法可能引发 DOMException of one of the following types:

异常	描述
InvalidStateError	Occurs if the method was not called from a versionchange transaction callback. For older WebKit browsers, you must call first.
TransactionInactiveError	Occurs if a request is made on a source database that doesn't exist (e.g. has been deleted or removed.) In Firefox previous to version 41, an InvalidStateError was raised in this case as well, which was misleading; this has now been fixed (see bug 1176165 )。
NotFoundError	You are trying to delete an object store that does not exist. Names are case sensitive.

范例

var dbName = "sampleDB";
var dbVersion = 2;
var request = indexedDB.open(dbName, dbVersion);
request.onupgradeneeded = function(e) {
  var db = request.result;
  if (e.oldVersion < 1) {
    db.createObjectStore("store1");
  }
  if (e.oldVersion < 2) {
    db.deleteObjectStore("store1");
    db.createObjectStore("store2");
  }
  // etc. for version < 3, 4...
};
