I've followed the instructions here: https://community.qualtrics.com/XMcommunity/discussion/comment/32547#Comment_32547 to integrate katex into a survey for displaying equations. Interestingly, when I use "preview question" on a question with embedded katex, it displays fine in the pop-up window, as below:

I feel like maybe there's a command I'm missing somewhere that doesn't get triggered when doing the broader previews? Has anyone gotten math display to work properly (using katex or otherwise)?

Post your question html (as a code block).

Text block:

Globally/Always:

\\text{``Always between } t=1_1 \\text{ and } t=t_2:S\\text{"} means that the statement S must always be true for all time between t_1 \\text{ and } t_2. This is equivalent to \\text{``}G_{[t_1,t_2]}:S\\text{"}, where G stands for "globally"



Finally/Eventually:

Other Operators:

“∧” means “AND”

“∨” means “OR”

“¬” means “NOT”

“≤“ means “less than or equal to”

"≥“ means “greater than or equal to”`

Question JavaScript:
Qualtrics.SurveyEngine.addOnload(function() {jQuery(".katex").each(function() {

      katex.render(this.innerHTML, this, { throwOnError: false });

   });

});


Qualtrics.SurveyEngine.addOnReady(function()

{

   /*Place your JavaScript here to run when the page is fully displayed*/


});


Qualtrics.SurveyEngine.addOnUnload(function()

{

   /*Place your JavaScript here to run when the page is unloaded*/


});
