将cheerio对象转换为字符串

Question

I am extracting metatags from page:

$ = cheerio.load(html)
metaTags = $('meta')

and it works fine, but I need that metaTags array contain strings - not objects of cherrio, like here:

["<'meta something=1231'><'/meta'>", "<'meta sometag=44242'><'/meta'>"]

ps I dont need ' character it just stackoverflow.com missunderstaning

I have made such , method:

toHtml = (el) ->
  return el.html()

but it doesnt work : getting empty results (using map with it)

metaTags.map (i, el) -> console.log i.toHtml(el)

Answer 1

let arrayOfHTMLstrings = $('meta').toArray().map( (el, index) => el.toString() );

根据cheerio官方文档

Answer 2

Here you have a solution:

findMetaTags = (html) ->
  $ = cheerio.load(html)

  metatagsContainer = $('<p>')
  $('meta').each ->
    metatagsContainer.append $(this).clone()

  unless _.isEmpty(metatagsContainer)
    return metatagsContainer.html()

  return

Answer 3

var cheerio = require('cheerio')
var html = 'SOME_HTML_STRING'
var $ = cheerio.load(html)
var htmlString = $.html()

Answer 4

I had problems with all of the answers here.

myNode.html() didn't find html() method in a lot of cases I tried. myNode.toString() returned [object Object] .

What finally worked every time was using the html() method on the cheerio itself.

const cheerio = require("cheerio")
cheerio.html( myNode )

This will convert any node to html string, in a loop or otherwise.
