Class: Cheerio<T>

The cheerio class is the central class of the library. It wraps a set of elements and provides an API for traversing, modifying, and interacting with the set.

Loading a document will return the Cheerio class bound to the root element of the document. The class will be instantiated when querying the document (when calling $('selector')).

Example

<ul id="fruits">
  <li class="apple">Apple</li>
  <li class="orange">Orange</li>
  <li class="pear">Pear</li>
</ul>

  '<span>Span 1</span><strong>Strong</strong><span>Span 2</span>',
);
const wrap = $('<div><p><em><b></b></em></p></div>');
$('span').wrapAll(wrap);

▸ filter<T, S>(this, match): Cheerio<S extends string ? Element : T>

Iterates over a cheerio object, reducing the set of selector elements to those that match the selector or pass the function's test.

• When a Cheerio selection is specified, return only the elements contained in that selection.
• When an element is specified, return only that element (if it is contained in the original selection).

not

▸ not<T>(this, match): Cheerio<T>

Remove elements from the set of matched elements. Given a Cheerio object that represents a set of DOM elements, the .not() method constructs a new Cheerio object from a subset of the matching elements. The supplied selector is tested against each element; the elements that don't match the selector will be included in the result.

T	extends AnyNode

Parameters

Name	Type	Description
