Hi,

   The option resources: "usable" is loading all scripts along with css, images and iframes while using jsdom.fromFile for loading a html document. Is there an option where I can load only a script and not load css, images or iframes. I am trying to dynamically execute some jquery functions on the html in my body, that does not require to load css, images or iframes. I used a window.close() after my operations, but this seems to be an incomplete solution. Can you please suggest on this.

Thank you.

Thank you for the response. But what are the options to be provided to disable executing css, images and iframes but execute all scripts. I could not find any good examples on custom resource loader. Any pointers would be appreciated.

Thank you.

Hi,

  Tried below and it worked. it's not loading iframes now.

let jsdom = require('jsdom');
class CustomResourceLoader extends jsdom.ResourceLoader {
fetch(url, options) {
  if (options.element.localName.toLowerCase() === 'iframe' || options.element.localName.toLowerCase() === 'css'
  || options.element.localName.toLowerCase() === 'img') {
return null;
//console.log(`Element ${options.element.localName} is requesting the url ${url}`);
  }
  return super.fetch(url, options);
}
}
const options = {
runScripts: 'dangerously',
resources: new CustomResourceLoader()                   
};
jsdom.JSDOM.fromFile(uri, options).then(function (dom) { }

Thank you Domenic.

Regards
Balaji.
