Hi @dobldsoft
I hope you well, I have the same issue with learndash. Im just wondering if you got any fix for it yet.
Hi,
This is slightly dirty, but does adding this to functions.php work?
add_action( 'wp_print_footer_scripts', function() {
if ( is_singular( 'sfwd-quiz' ) ) {
?>
<script>
(function($) {
renderKatex = function() {
const eles = document.querySelectorAll(".katex-eq");
for(let idx=0; idx < eles.length; idx++) {
const ele = eles[idx];
try {
katex.render(
ele.textContent,
ele,
{
displayMode: ele.getAttribute("data-katex-display") === 'true',
throwOnError: false
}
);
} catch(n) {
ele.style.color = "red";
ele.textContent = n.message;
}
}
};
jQuery('.wpProQuiz_content').on('learndash-quiz-answer-response-contentchanged', function(e) {
renderKatex();
});
jQuery('.wpProQuiz_content').on('learndash-quiz-init', function(e) {
renderKatex();
});
})( jQuery );
</script>
<?php
}
}, 999);
Thank you for this and for making the plugin
@beskhue The plugin is super useful
Hi @beskhue,
Thank you for your dirty (:-)) solution. It does the job!!
I’ve just modified
const eles = document.querySelectorAll(".katex-eq");
to
const eles = document.querySelectorAll(".katexresponse");
and used the katexresponse as class for the div in the Learndash quiz anwers
Otherwise all the already present katex get rendered twice, 3 times or more.
Thank you again for your help!
@dobldsoft You are right.
In the current development version — not yet officially released, available for download here https://wordpress.org/plugins/katex/advanced/ — I’ve added a function to make this easier. You can simply call katexRender to render all as yet unrendered KaTeX.
This changes the code snippet to:
add_action( 'wp_print_footer_scripts', function() {
if ( is_singular( 'sfwd-quiz' ) ) {
?>
<script>
(function($) {
jQuery('.wpProQuiz_content').on('learndash-quiz-answer-response-contentchanged', function(e) {
katexRender();
});
jQuery('.wpProQuiz_content').on('learndash-quiz-init', function(e) {
katexRender();
});
})( jQuery );
</script>
<?php
}
}, 999);
@beskhue Using the Not yet released version with the new code snippet! It still does not render learndash quiz answers. Do I need to use div and a class? How would I do that? or any suggestion on how to get it to render learndash quiz answers?
Also, I still need to change this
add_action('loop_end', 'katex_resources_enqueue');
to
add_action('wp_footer', 'katex_resources_enqueue');
For it to work with learndash, else I will be getting the ‘katex is not defined’ error
Thank you so much for your time.
