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

This is the HTML markup we will be using in all of the API examples:

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

Type parameters

Name	Type
T	extends AnyNode

Parameters

  '<div id=test>\n  <div><p>Hello</p></div>\n  <div><p>World</p></div>\n</div>'
);
$('#test p').unwrap();

//=> <div id=test>
//     <p>Hello</p>
//     <p>World</p>

Example

with selector

const $ = cheerio.load(
  '<div id=test>\n  <p>Hello</p>\n  <b><p>World</p></b>\n</div>'

wrapAll

▸ wrapAll<T>(this, wrapper): Cheerio<T>

The .wrapAll() function can take any string or object that could be passed to the $() function to specify a DOM structure. This structure may be nested several levels deep, but should contain only one inmost element. The structure will be wrapped around all of the elements in the set of matched elements, as a single group.

Type parameters

Name	Type
T	extends AnyNode

Parameters

Name	Type	Description
this	Cheerio<T>	-
wrapper	AcceptedElems<T>	The DOM structure to wrap around all matched elements in the selection.

Returns

The instance itself.

Example

With markup passed to `wrapAll`

const $ = cheerio.load(
  '<div class="container"><div class="inner">First</div><div class="inner">Second</div></div>'
);
$('.inner').wrapAll("<div class='new'></div>");

//=> <div class="container">
//     <div class='new'>
//       <div class="inner">First</div>
//       <div class="inner">Second</div>
//     </div>
//   </div>

Example

With an existing cheerio instance

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

//=> <div>
//     <p>
//       <em>
//         <b>
//           <span>Span 1</span>
//           <span>Span 2</span>

▸ 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.

The .not() method can take a function as its argument in the same way that .filter() does. Elements for which the function returns true are excluded from the filtered set; all other elements are included.

Type parameters

Name	Type
T	extends AnyNode

Parameters

Name	Type	Description
