How do get script content using cheerio

Tags:

I am using the cheerio lib and am trying to get this script field - script type="application/json" But for some reason it can not find these script tags. What is wrong? How do I fix?

var $ = require('cheerio')
var parsedHTML = $.load(html)
console.log( parsedHTML('script').get().length ); // this is 0

If you use

var parsedHTML = $.load('<html><head><script type="application/json" src="http://myscript.org/somescript.ks"></script></head></html>')
console.log( parsedHTML('script').get()[0].attribs['src'] ); 

You can fetch a url and then use the request to fetch the contents

If you want to get at an inline script, you can do this:

console.log( parsedHTML('script').get()[0].children[0].data );

To those still wandering into this thread, the following solution worked for me:

const $ = cheerio.load(html, {xmlMode: false});
$('script').length; // no longer 0

(See htmlparser2's options)
