API

extractOpengraph(node, prefix)

• node - The node (or window element) you want to extract OG metadata from.
• prefix - Optional. Defaults to 'og:'. If you want to extract metadata with a prefix other than og:, you may specify it here.

Returns: An object containing key value pairs extracted from your meta tags that match the prefix, with the property attributes as the keys (with the prefix stripped) and the content attributes as the values.
