content.forEach is not a function when loading node that is not a root

[NeverBehave]

I don't know whether is it an undocumented behavior or not, when trying to load a node that is not a root, cheerio will try to parse it as a list of nodes.

I believe this commit cause such break: 2e75c2a#diff-cc0e533610b6395aec57bad8971c3692fbf20950660cc5aa5014e58333a738baR28

Minimal Example

similar usage https://stackoverflow.com/questions/39044690/cheerio-map-strange-behaviour

const cheerio = require('cheerio');
const html = `
    <div class="test">
        <div></div>
        <div></div>
    <div>
`

cheerio.load(html)('.test').map((i, e) => {
    cheerio.load(e) // Break, not a root and not an array
})

If this is the desired behavior, what are the alternative ways to workaround this? Thanks!

Thanks for the report! I've opened #1580 to fix this.

To help with your issue in the meantime: Typically, the function returned by cheerio.load is used to wrap elements in loops. For you, this would be:

const $ = cheerio.load(html);
$('.test').map((i, e) => {
    $(e).html() // `.html` as one example.
})
