Description of this parameter from the json schema.

Parameters

Google Chrome Extensions (Labs)

Bookmarks

Bookmarks

Use the chrome.bookmarks module to create, organize, and otherwise manipulate bookmarks. Also see Override Pages, which you can use to create a custom Bookmark Manager page.

Clicking the star adds a bookmark

Manifest

You must declare the "bookmarks" permission in the extension manifest to use the bookmarks API. For example:

{
  "name": "My extension",
  ...
  "permissions": [
    "bookmarks"
  ],
  ...
}

Objects and properties

Bookmarks are organized in a tree, where each node in the tree is either a bookmark or a folder (sometimes called a group). Each node in the tree is represented by a BookmarkTreeNode object.

BookmarkTreeNode properties are used throughout the chrome.bookmarks API. For example, when you call create(), you pass in the new node's parent (parentId), and, optionally, the node's index, title, and url properties. See BookmarkTreeNode for information about the properties a node can have.

Note: You cannot use this API to add or remove entries in the root folder. You also cannot rename, move, or remove the special "Bookmarks Bar" and "Other Bookmarks" folders.

Examples

The following code creates a folder with the title "Extension bookmarks". The first argument to create() specifies properties for the new folder. The second argument defines a function to be executed after the folder is created. 

chrome.bookmarks.create({'parentId': bookmarkBar.id,
                         'title': 'Extension bookmarks'},
                        function(newFolder) {
  console.log("added folder: " + newFolder.title);
});

The next snippet creates a bookmark pointing to the developer documentation for extensions. Since nothing bad will happen if creating the bookmark fails, this code doesn't bother to define a callback function. 

chrome.bookmarks.create({'parentId': extensionsFolderId,
                         'title': 'Extensions doc',
                         'url': 'http://code.google.com/chrome/extensions'});

For an example of using this API, see the basic bookmarks sample. For other examples and for help in viewing the source code, see Samples.

API reference: chrome.bookmarks
