Hi all,

I´d like to create a mathematical quiz for students in limesurvey.

But when I paste the mathematical terms into lime survey, they are displayed differently.
:
Here you have an example of what the term should look like:



and what it actually looks like after having pasted it into limesurvey :



This problem also affects fractions and other mathematical terms.

Do you know a solution to solve this problem?

Thanks a lot for sharing your ideas with me.


Kind regards and thanks a lot


Maria

This issue is unrelated to LimeSurvey. It's a HTML Browser issue.
Cut and paste will not work in most cases.

Most common approach is to create an image for every math equation.

Newer technologies are available, but might not work in the browser your respondents are using.
developer.mozilla.org/en-US/docs/Web/MathML

Some symbols can be accessed in the UTF fonts (even older browsers can display them).

Seems include MathML directly in source code is OK, just need
1. No XSS protection
2. add the declaration line

I just quickly test on Firefox :)

XSS protection and AJAX mode are the first things you need to disable to get LS in a usable state. Sad, but true.


But mariaa should use MathML only if respondents are using a predefined browser.

Yes but we STILL must disable XSS for common admin user . Because it muts be a decision to allow any admin usere to put XSS and javascript :).

We already disable XSS for super-admin : i think it's OK, but not for other admin (by default) : think it's OK too.

About MathML : how great firefox \o/

Hi Jelo,

thanks a lot for your help! Creating images of the equations seems to be the easiest option. I`ll try thar =)

Thanks a lot Denis!

Since I´ve never used MathML before but if Jelo´s suggestion ( creating an image for every math equation) is not working, I´ll get to grips with this topic.
