Get the average from 5 drop downs in CGFeedback

[luukftw]

I'm using the CGFeedback module to give feedback on 5 questions that must be rated between 1-5. I added the 5 questions and drop downs as custom fields. They work much like the original default option.

Now I want the page to create 1 rating based on the averages of the 5 custom options, and round it to a whole number between 1-5 , and pass that as the final rating.

This is the page I'm working on. This is the relevant HTML

Code: Select all

                <div class="row">
      <div class="col-md-4 text-right">
        <label for="m54f83field_5">Vraag 1 : Hoe is u ervaring geweest met het wachten:</label>

The drop down on the bottom with the ID rating (which now is visible but will be hidden), is the one I want to change to get the average of the above 5 fields. I tried to do this with a javascript, but I can't seem to get the values. Hope someone has any idea how to do such a thing. Thanks

Edit: Forgot to mention, the average needs to be parsed as $rating. Currently the rating is get the following way. {html_options options=$rating_options selected=$rating}

I think that this would be easy using jQuery. Probably it's not even that hard with just plain JS.

However, I think it's generally not a good idea to do calculations client side. Wouldn't it be possible to do the math within CMSMS using a UDT or some smarty?

Smarty {math} should do the trick.
