Web-interface for Delphi Method III

This post is the third in the series describing the web-interface I created to administer a questionnaire with the Delphi method. In this post I describe the code used to give feedback to the participants in round 2 of the Delphi study on functional magnetic resonance imaging on tinnitus. If you are interested in the previous posts, this post describes the interface for round 1 whereas this post describes (the first part of) the interface for round 2.

As represented in the figure above, in round 2 the Delphi interface displayed one question and two bar plots showing the distribution of experts’ responses for the given question in round 1. To keep the post short and to the point, I divided the description of the interface for round 2 into two parts.

Uploading data to the server [wbwit II]

The problem is that there is a limit on the size of data which could be transfered with an ajax XMLHttpRequest (ajax call from now on) from the web-page to the host server. It took quite a bit of trial-and-error to discover that the problem was
