Recently, I have been experimenting with the
phantomjs-node library. The thing I wanted to achieve was basically to create a dynamic web-page template, employ the
phantomjs-node library to "run" it, and finally extract some data from the rendered page.
In the simplest setting, the first attempt to approach this looked like this (in the example below, the template is just static, nevertheless it might contain in principle some further logic utilizing external libraries, etc.):...

- Don't use
co+ generator functions any more.
- Yes, you should transform all event callbacks that fire (at most) once into promises.
- No, don't ever create promises like that and "resolve them externally". Just put the stuff that resolves them inside the promise constructor.
My goal is to scrape some data from a web site using Node.js.
I already managed to scrape data using only
request package, but the site that I want scrape has dynamic content, and
request only can't grab this dynamic data.
So I did some research and found that, to achieve that, and based in this SO question, I would need to install some packages via
npm (I do not know if all three are needed):
Based on the question too, I used the same code, just to understand how it works:

I am not sure where you got the format from but the latest phantom JS does not use callbacks and uses promises instead. And the constructor (Phantom.create) expects configs in form of array and not a callback function.
Your code need's to be something similar to this I presume(I have not tested this but should run).
Consider code from node-phantom:...

If the variable is serializable you could do it this way
Hi I am trying to parse a website which has live football scores. Using NodeJS and PhantomJS together (phantomjs-node). The thing is I am not able to run JQuery in
page.evaluate on an element because I assume page content doesn't have the element I want to parse. Here I have a simple example and the element I can't see is called "resultsList". If I run
$("#resultsList").html() on the console of a web browser I can get the inner html though.

There are 2 possibilities
the website dont have jQuery inside
Solution: injectJs("/absolute path of jQuery in your system/");
- the website have JQuery
Solution: Cannot find the particular element.
Open Chrome execute the same query and paste inside the evaluate.
- the website have JQuery Solution: Cannot find the particular element.
NodeJS newbie here. I am trying to parse html with using NodeJS and PhamtomJS (phantomjs-node). When I run the the JQuery
$("[class*='question-summary']") from the browser console it returns an array. However, I couldn't manage to do the same thing on nodejs. I guess stackoverflow has JQuery so I don't need to use
includeJs to load jquery. Actually, when I run
Here is the nodejs example I am running;...

Answering my own question here. Creating an array inside evaluate function and pushing elements inside worked. I guess the only limitation is
phantom-node just supports returning objects with primitives.
