Cheerio: Get a Javascript object using cheerio

[rajkumarpb]

So, I have scraped the HTML using cheerios and among the HTML, there is some information which I need as an JSON Object. To get the JSON, what I'm doing as of now is, looping through all scripts and get the json, and get the value!! :cry: Is there any better approach for this? I've even tried with some regEx but it failed!!

*_Regex code : *_

var regex = /product_price:?$/g;
//var regex = /product_price:\\d/g;
var results = regex.exec($.html());

HTML

<script>
var utag_data = {"request_sessionid": "", "request_ipaddress": "xxx.xxx.x.x", 
"product_id": "9372", "customer_city": "xxxxxx", "siftscience_api_key": "77b4eca14b",       "product_price_readable": "4999.00", "user_username": "", 
"product_price": "499900", "request_method": "GET", "country_code": "IN", 
"product_platform": "PC", "product_sku": "Tom Clancys The Division - PC",   "user_is_authenticated": "False", "customer_country": "India", 
"product_name": "Tom Clancy's The Division", "currency_code": "INR",
 "request_path": "/s/in/en/pc/games/action/tom-clancys-division/"};
</script>

*_Cheerios Code : *_

var temp = '';
var json = '';

    $('script').each(function(i, elem) {
      temp = $(this).text(); 

      if(temp.indexOf("var utag_data")!== -1){              
        json = temp.substring(json.indexOf("{"), json.length-2);            
        json = JSON.parse(json);
        return false;
      }
      //console.log($(this).text());
    });

Cheerio doesn't provide any tools to make your task any easier. Because you are trying to parse JavaScript code (and _not_ JSON), any approach based on simple pattern matching is likely to be brittle.

I would recommend using Cheerio to scrape the contents of the <script> tag and feeding that code to a proper JavaScript parser like Shift, Acorn or Esprima. Those tools will output an AST which you can
programatically traverse for the values you need.
