    example
    $('.apple', '#fruits').text();
    //=> Apple

    $('ul .pear').attr('class');
    //=> pear

    $('li[class=orange]').html();
    //=> Orange

load

load: (content: string | Node | Node[] | Buffer, options?: null | CheerioOptions, isDocument?: boolean) => CheerioAPI

Type declaration

    • Create a querying function, bound to a document created from the provided markup.

      Note that similar to web browser contexts, this operation may introduce <html>, <head>, and <body> elements; set isDocument to false to switch to fragment mode and disable this.

      see

      https://cheerio.js.org#loading for additional usage information.

      Parameters

      • content: string | Node | Node[] | Buffer

        Markup to be loaded.

      • Optional options: null | CheerioOptions

        Options for the created instance.

      • isDocument: boolean = true

        Allows parser to be switched to fragment mode.

      Returns CheerioAPI

      The loaded document.

Methods

contains

parseHTML

  • parseHTML(data: string, context?: unknown, keepScripts?: boolean): Node[]
