Combine EM and Javascript was created by pvdemael
Hi all,
Is it possible to combine Javascript and Expression Manager?
I need to parse input data to generate a value where Javascript should come in handy.
If possible, could someone show me a simple example to demonstrate this, eg read 2 variables and add them in Javascript and use this value in the Expression Manager?
Thx

If it came down to that I would use pure JS.

Thx Tony,
However, I am not very familiar with Javascript, I can read code and adjust it, but not start something from scratch.
Could someone show me an example of how to calculate a sum of two variables and save the value?
Isn't it the best way to save the value in an Equation question to put it in the database?
If I have a start, I think I will be able to tune it to my needs.
Thx in advance

Well, assuming you had two text or numeric questions on a previous page (q1 and q2), placing this in the source of a text question should load that question with the sum of the previous questions.
Code:
<script type="text/javascript" charset="utf-8"> $(document).ready(function() { // Define some variables var thisQuestion = $('#question'+qID); var q1Value = '{q1.shown}'; var q2Value = '{q2.shown}'; var sumValue = Number(q1Value) + Number(q2Value); // Load the question $('input[type="text"]', thisQuestion).val(sumValue); // Hide this question $(thisQuestion).hide(); }); </script>

Hi,
I think it's easier to compute scores using EM.
However, there is still a benefit of using javascript and a numerical input type question if you need some public statistics...As far as I know equations type questions are note supported
To try it:
1) create 2 numerical questions (q1 and q2)
2) create another numerical question (sum) pasting the following code in the source:
/!\ Set your survey question by question (or group by group if the "sum" question is placed in another questiongroup)
.

Hi Ben_V and Tony,
This is what I need!
I did not know you could use EM expressions that way which makes it very powerful.
A suggestion is to put this in the manual (maybe a 'for dummies' section?).

For the same pupose, i prefer to use 'assigment' operator.
Q1 : first value
Q2 : 2nd value
NUMSTAT: numerci question type hidden
EQUA : Equation question type with : {NUMSTAT=sum(Q1,Q2)} hidden
