Json with processing.js

VeronicaHue

Hi, I tried using Pomax example with Json, but without succes. The code used is here http://processingjs.org/articles/PomaxGuide.html#json . The only thing I modified is that

var json = $.get("http://thatfunkysite.com/serving/json.asp"); becomes

var json = $.get("/path/to/points.json");

What else should I change? I looked everywhere on the internet and couldn't find a solution.

I also came across this piece of code, which works fine as .pde, but doesn't work as processing.js

// Declare some global variables
JSONObject response;
String videoTitle; 

void setup() {
  // Load the JSON file as a JSON object
  response = loadJSONObject("response.json");

  // Get the array of items from the JSON object
  JSONArray items = response.getJSONArray("items");

  // Get the first item in the JSON array
  JSONObject firstVideo = items.getJSONObject(0);

  // Get a JSON Object with a list of details about the first item
  JSONObject snippet = firstVideo.getJSONObject("snippet");

  // Get title the string from final JSON object
  videoTitle = snippet.getString("title");

  // Print the title of the first video result
  println(videoTitle);
}

I simply need a simple, working code that deals with JSON in processing.js

Thank you!

When Processing 2's come out, it brought along some new data structures like JSONObject, Table, IntList, etc.
And renamed XMLElement to just XML and raised its # of methods.

Old Processing 1.5.1 had only XMLElement as an "exclusive" data structure class apart from some Java's built-in 1s!

But why I'm telling you all these? B/c the corresponding PJS library is still pretty much similar to P5 1.5.1!
We still can't use the newer classes & methods from P5 2.x.x series and on in "JavaScript Mode"!

Thank you so much! I will use XMLelement for playing with my data. It;s just as good with what I need :) I tried the example here http://processingjs.org/reference/XMLElement/ and it's perfect :)

Glad XML is as good as JSON for ya! :D
Just remember that you can still test it in "Java Mode" if you rename XMLElement as XML! ;)
