Loading and selecting an external DOM Element with jsdom

anyhowat

Hi,

I’m trying to write a module which loads a DOM-element of a remote URL with JSDOM.
https://github.com/anyhow/MMM-scrape

Example usecase: Displaying the current onair artistname and songtitle of a radio station.
(In the example: The Span-Elements with the class “playing” at https://fm4.orf.at/player/live)

@fewieden did something similar before, but I’m not able to adapt it:
https://github.com/fewieden/MMM-VocabularyTrainer/blob/master/apis/geschichtsvereinkoengen.js#L89

I can’t get jsdom to work at all. Anybody could have a look and have some tips? Do I need to put it into a node_helper?

Thanks.

i can work on it more in a couple hours… (grandson socker game)

I misread it in a hurry…
worked thru it, further down

Also, you can’t use require in the module.js

Only in node_helper.

Turn on the developers window, ctrl-shift-i , and select the console tab and scroll up to see any errors

@anyhowat i updated your code to a small working sample… i created a pull request back to you with the updates

but the node you are looking for on the site (span.playing) does not exist.
I added debugging to dump the content returned from the jsdom api request

also, after installing your module (or pulling my updates after merge), you need to do

npm install

in the module folder, to get the jsdom library loaded from your module

Sam, thanks. That’s awesome.
I’ll dig into the changes right now. Made my day.
