Im using cheerio to do some scraping and want to access the head js element on a page (notably instructables). I can access it but it es back as function.

So using this:

  console.log($('script').attr('type', "application/ld+json").text);

• (on this: !/step3/Cut-the-project-box/)

• this provides 'Function'

• I thought strinify would work but it doesn't :(

• 1 text() is a function to get the text content of the tag, which is probably empty if the script has a .src. what are you trying to get? – dandavis Commented Mar 27, 2017 at 17:54
• It's not a src. It's the content of a script tag. .text and .data seem to be giving the same thing. runkit./58d97359d2dfbd0014d162e2/58d97359d2dfbd0014d162e3 – willwade Commented Mar 27, 2017 at 21:47

This is because $("script").attr("type","application/ld+json"); returns an array of script tags (there's more than only one script tag on the page) and it's also changing the type of all script tag of the page to application/ld+json

See JQuery .attr() documentation.

If you need to get the one with that type $("script[type='application/ld+json']") will do the trick.

var request = require('request');
var cheerio = require('cheerio');

request('http://www.instructables./id/Making-an-online-Fish-Tank-webcam!/step3/Cut-the-project-box/', function (error, response, html) {
  if (!error && response.statusCode == 200) {
    var $ = cheerio.load(html);
    var obj = $("script[type='application/ld+json']"); 

    for(var i in obj){
        for(var j in obj[i].children){
            var data = obj[i].children[j].data;
            if(data){
               console.log(data);
            }
        }
    }
  }
});
