A StorageEvent is sent to a window when a storage area it has access to is changed within the context of another document.

Note: Although this event existed prior to Gecko 2.0, it did not match the specification. The old event format is now represented by the nsIDOMStorageEventObsolete interface.

Method overview

void initStorageEvent(in DOMString typeArg, in boolean canBubbleArg, in boolean cancelableArg, in DOMString keyArg, in DOMString oldValueArg, in DOMString newValueArg, in DOMString urlArg, in nsIDOMStorage storageAreaArg);

Attributes

Attribute Type Description
key DOMString Represents the key changed. The key attribute is null when the change is caused by the storage clear() method. Read only.
newValue DOMString The new value of the key. The newValue is null when the change has been invoked by storage clear() method or the key has been removed from the storage. Read only.
oldValue DOMString The original value of the key. The oldValue is null when the key has been newly added and therefore doesn't have any previous value. Read only.
storageArea nsIDOMStorage Represents the Storage object that was affected. Read only.
url DOMString The URL of the document whose key changed. Read only.
