Type Parameters
• T extends AnyNode
• S extends string
Parameters
• selector?: S | BasicAcceptedElems<T>
Either a selector to look for within the document, or the contents of a new Cheerio instance.
• context?: null | BasicAcceptedElems<AnyNode>
Either a selector to look for within the root, or the contents of the document to query.
• root?: BasicAcceptedElems<Document>
Optional HTML document string.
• options?: CheerioOptions
Returns
Cheerio<S extends SelectorType ? Element : T>
Example
$('ul .pear').attr('class');

$('ul', '<ul id="fruits">...</ul>');
Or as the root:
$('li', 'ul', '<ul id="fruits">...</ul>');
