MDN 7/22/2015

I am working on related_content button in MDN. This button allows users to retrieve drupal nodes related to the selected elements in the diagrams. I had a simpler functionality in the beginning of the project that allows users to click on a single diagram element to retrieve related nodes. I spent some time to figure out how to send an array of ids from client to server via ajax; most examples send only parameters. I have not finished today as I worked only a couple of hours; I should be done tomorrow.
