How do get script content using cheerio

Question

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

I add some code. It's not finding an script tags. Does cheerio not support script? — CWon, Jul 04 '14 at 02:28
That exact code, copied and pasted, using a text string that has the line `` in it? Returns `1` for me. — Matthew Bakaitis, Jul 04 '14 at 04:31

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 );

The second option here seems to fail when a `<=` operator is encountered – Trevor Feb 28 '18 at 23:33
You probably saved me a lot of time. Thanks a lot! – maxime1992 Oct 05 '18 at 14:07

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)
