externalmap

map<T, M>(this, fn): Cheerio<M>

Pass each element in the current matched set through a function, producing a new Cheerio object containing the return values. The function can return an individual data item or an array of data items to be inserted into the resulting set. If an array is returned, the elements inside the array are inserted into the set. If the function returns null or undefined, no element will be inserted.
Parameters
- externalthis: Cheerio<T>
- externalfn: (this, i, el) => undefined | null | M | M[]
  Function to execute.
Returns Cheerio<M>
The mapped elements, wrapped in a Cheerio collection.
$('li') .map(function (i, el) { // this === el return $(this).text(); }) .toArray() .join(' '); //=> "apple orange pear"

externalnextAll

nextAll<T>(this, selector): Cheerio<Element>

externalnextUntil

nextUntil<T>(this, selector, filterSelector): Cheerio<Element>

Gets all the following siblings up to but not including the element matched by the selector, optionally filtered by another selector.

externalnot

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.
Parameters
- externalthis: Cheerio<T>
- externalmatch: AcceptedFilters<T>
  Value to look for, following the rules above.
Returns Cheerio<T>
The filtered collection.
$('li').not('.apple').length; //=> 2
$('li').not(function (i, el) { // this === el return $(this).attr('class') === 'orange'; }).length; //=> 2
