nsINavBookmarksService 编辑

toolkit/components/places/nsINavBookmarksService.idlScriptable The BookmarksService interface provides methods for managing bookmarked history items. Bookmarks consist of a set of user-customizable folders. A URI in history can be contained in one or more such folders. 1.0 67 Introduced Gecko 1.8 Inherits from: nsISupports Last changed in Gecko 14.0 (Firefox 14.0 / Thunderbird 14.0 / SeaMonkey 2.11)

Implemented by: @mozilla.org/browser/nav-bookmarks-service;1. To use this service, use:

var navBookmarksService = Components.classes["@mozilla.org/browser/nav-bookmarks-service;1"]
                          .getService(Components.interfaces.nsINavBookmarksService);

Attributes

AttributeTypeDescription
bookmarksMenuFolderlong longThe item ID of the Bookmarks Menu folder. Read only. Note: Renamed from bookmarksRoot in Gecko 1.9
placesRootlong longThe item ID of the top-level folder that contains bookmarks, tags and all other Places data. This contains administrative data as well as user data, and is therefore not recommended for use in queries. Read only.
tagsFolderlong longThe item ID of the top-level folder that contains the tag "folders". Read only. Note: Renamed from tagRoot in Gecko 1.9
toolbarFolderlong longThe item ID of the personal toolbar folder. Read only. Note: Renamed from toolbarRoot in Gecko 1.9
unfiledBookmarksFolderlong longThe item ID of the Unfiled Bookmarks folder. Read only.

Constants

ConstantValueDescription
DEFAULT_INDEX-1This is the default index; this value should be used for APIs that allow passing in an index where the index is not known or is not required to be specified, such as when appending an item to a folder.
TYPE_BOOKMARK1This is an index for type "Bookmark".
TYPE_FOLDER2This is an index for type "Folder".
TYPE_SEPARATOR3This is an index for type "Separator".
TYPE_DYNAMIC_CONTAINER4This is an index for type "Dynamic Container". Dynamic containers were removed in Gecko 11, but the type index remains to prevent reuse.

Methods

addObserver()

This method adds a bookmark observer. If ownsWeak is false, the bookmark service will keep an owning reference to the observer. If ownsWeak is true, then aObserver must implement nsISupportsWeakReference, and the bookmark service will keep a weak reference to the observer.

void addObserver(
  in nsINavBookmarkObserver observer,
  in boolean ownsWeak
);
Parameters
observer
The bookmark observer to be added.
ownsWeak
The owning reference state (boolean).

beginUpdateBatch()

Obsolete since Gecko 1.9 (Firefox 3)

Causes observers to be notified of a beginUpdateBatch when a lot of things are about to change. Calls can be nested, observers will only be notified when all batches begin/end.

It is EXTREMELY IMPORTANT that you call EndUpdateBatch() for each call to beginUpdateBatch. If you do not do this, certain parts of the UI will not get updated and any changes to bookmarks will not get written to disk. From C++ code inside the places component, use nsBookmarksUpdateBatcher defined in nsNavBookmarks.h to scope batches. For JS or from other components, just please be very careful to close the batch, especially when encountering an error and returning early.

void beginUpdateBatch();
Parameters

None.

changeBookmarkURI()

This method changes the bookmarked URI for a bookmark. It changes which "place" the bookmark points at, which means all annotations, and so on are carried along.

void changeBookmarkURI(
  in nsIURI oldURI, Obsolete since Gecko 1.9
  in long long aItemId,
  in nsIURI aNewURI
);
Parameters
oldURI Obsolete since Gecko 1.9
The URI of the item to be changed.
aItemId
The item whose bookmark URI needs to be changed.
aNewURI
The new URI.

Obsolete since Gecko 13.0 (Firefox 13.0 / Thunderbird 13.0 / SeaMonkey 2.10)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

This method creates a dynamic container under the given parent folder.

long long createDynamicContainer(
  in long long aParentFolder,
  in AUTF8String aName,
  in AString aContractId,
  in long aIndex
);
Parameters
aParentFolder
The ID of the parent folder.
aName
The name of the new folder.
aContractId
The contract ID of the service which is to manipulate this container.
aIndex
The index to insert at, or DEFAULT_INDEX to append to the end of the list.
Return value

Returns the ID of the newly-inserted folder.

createFolder()

This method creates a new child folder and inserts it under the given parent.

long long createFolder(
  in long long aParentFolder,
  in AUTF8String name,
  in long index
);
Parameters
aParentFolder
The ID of the parent folder.
name
The name of the new folder.
index
The index to insert at, or DEFAULT_INDEX to append to the end of the list.
Return value

Returns the ID of the newly-inserted folder.

endUpdateBatch()

Obsolete since Gecko 1.9 (Firefox 3)

Causes observers to be notified of an endUpdateBatch when a batch is done changing. Should match beginUpdateBatch() or bad things will happen.

void endUpdateBatch();
Parameters

None.

exportBookmarksHTML()

Obsolete since Gecko 1.9 (Firefox 3)

Saves the current bookmarks hierarchy to a bookmarks.html file.

void exportBookmarksHTML(
  in nsIFile file
);
Parameters
file
The nsIFile to export the bookmarks to.

getBookmarkedURIFor()

This method is used to see if the given URI is bookmarked, or any page that redirected to it is bookmarked. For example, if I bookmark "mozilla.org" by manually typing it in, and follow the bookmark, I will get redirected to "www.mozilla.org". Logically, this new page is also bookmarked. This function, if given "www.mozilla.org", will return the URI of the bookmark, in this case "mozilla.org".

Note: Will only return bookmarks in the first 3 levels of redirection (1 -> 2 -> 3 -> aURI).
nsIURI getBookmarkedURIFor(
  in nsIURI aURI

Parameters
aURI
The URI that needs to be checked if it is bookmarked or not.
Return value

);
Parameters
aURI
The URI whose keyword is to be retrieved.
Return value

getRemoveFolderTransaction()

This method retrieves an undo-able transaction for removing a folder from the bookmarks tree. This method exists because complex delete->undo operations rely on recreated folders to have the same ID they had before they were deleted, so that any other items deleted in different transactions can be re-inserted correctly.

The GUID string.

setItemIndex()

This method changes the index for a item. This method does not change the indices of any other items in the same folder, so ensure that the new index does not already exist, or change the index of other items accordingly, otherwise the indices will become corrupted.

Warning: This is API is intended for scenarios such as folder sorting, where the caller manages the indices of all items in the folder. You must always ensure each index is unique after a reordering.

void setItemIndex(
  in long long aItemId,
  in long aNewIndex
);
Parameters
aItemId
The ID of the item to modify.
aNewIndex
The new index.
Exceptions thrown
 
If aNewIndex is out of bounds.

setItemLastModified()

Note: This is the only method that will send an itemChanged notification for the property. lastModified will still be updated in any other method that changes an item property, but we will send the corresponding itemChanged notification instead.
void setItemLastModified(

);
Parameters
aItemId
The ID of the item whose last modified time is to be set.
