What is the best way to transfer data from processing.js to a rails application?

I am working on a basic canvas project using processing.js, and I am wondering how I can transfer data from my Rails application to Processing.js.

void drawBox(int bx, int by, int bs, int bs){
      strokeWeight(3); 
      stroke(50,50,50);
      // Test if the cursor is over the box 
      if (mouseX > bx-bs && mouseX < bx+bs && 
          mouseY > by-bs && mouseY < by+bs) {
        bover = true;
       if(!locked) { 
          fill(181,213,255);
        } 
      } else {
        fill(255);
          bover = false;
      }
      fill(192);
      stroke(64);
      roundRect(bx, by,80,30,10,10);
      // put in text 
      if (!isRight) {
        text("Box Value", x-size+5, y-5);
      //Here i need to pass value from my controller
      }
      else {
        text("Box Value", x+5, y-5);  
 //Here i need to pass value from my controller    
      }
    }

Instead of using the static string "Box Value," I would like to dynamically pass the value from something like @post.name using ajax.

Answer №1

One approach could be implementing this functionality through an RJS template, where you define a global variable containing the text or employ a data store to link it to a specific DOM element. Afterwards, in your processing.js file, you can utilize this variable to display the desired text content.

Answer №2

If you want to incorporate pure JavaScript into your processing code, you can visit

Therefore, fetching your data from AJAX using your preferred library should be a straightforward task.
