Hello, I was wondering if could I import such function like querySelector or querySelectorAll to use it inside function node? I've tried with: var doc = msg.payload; var querySelector = global.get('querySelector'); doc.querySelector("p"); without success...

querySelector is not a defined function in node.js - its a browser specific feature. There are npm modules available to provide similar functionality, such as cheerio you could add via functionGlobalContext, but for the example code you show, you can use the core HTML node to do pretty much exactly…

Thank you, but I would like to import a whole html page inside msg.payload then assigne some string to variables using css selectors in one function node using for example querySelector function. So should I install npm cheerio gloabally then import it? var querySelector = global.get('cheerio');

ok, thank you. I installed https://www.npmjs.com/package/query-selector then add line to settings.js: functionGlobalContext: { qs:require('query-selector') // os:require('os'), // jfive:require("johnny-five"), // j5board:require("johnny-five").Board({repl:false}) }, then restart node-red and…

From the readme of the query-selector module you have chosen shows it has to be used alongside jsdom: var querySelectorAll = require('query-selector'); var jsdom = require("jsdom").jsdom; var doc = jsdom('<html><div id="t"><span>1</span><span>2</span></div></html>'); var time = Date.now(); console.…

ok i see... ok jsdom installed and added: functionGlobalContext: { qs:require('query-selector') jsdom:require('jsdom') // os:require('os'), // jfive:require("johnny-five"), // j5board:require("johnny-five").Board({repl:false}) }, and... TypeError: doc.qs is not a function

sure: var doc = msg.payload; var qs = global.get('qs'); var jsdom = global.get('jsdom'); doc.qs("p"); [{"id":"8d1a968.84be568","type":"inject","z":"fb6d8306.816e6","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":300,"y":240,"wires…

So you import jsdom into your function, but you haven't used it. Look again at the query-selector example code. Look at where its doc variable comes from. (and please use the ``` quotes around blocks of function code in the same way you did your flow).

Ok, I installed cherio as you recommend. Another problem: [{"id":"8d1a968.84be568","type":"inject","z":"fb6d8306.816e6","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":300,"y":240,"wires":[["c1b49fbb.618cc"]]},{"id":"c1b49fbb.618cc",…

Did you modify your Function to match? (and when sharing code please follow the guidance in this post: How to share code or flow json)
