body: <p>I am creating a simple canvas using processing.js , how to pass values from rails application to Processing.js </p>
  
  <pre><code>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 &gt; bx-bs &amp;&amp; mouseX &lt; bx+bs &amp;&amp; 
            mouseY &gt; by-bs &amp;&amp; mouseY &lt; 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    
        }
      }
  </code></pre>
  
  <p>Instead of static string "Box Value" , I need to pass the value from the ex @post.name through ajax</p>
