run a JS script from a ggb button

ggbApplet.getValue("grade")

With your code, I get the value of grade but I want to launch the file store_score.js when I click th GGB button inside the GGB file.

In fact, I want to run an Ajax process from the GGB Button into the GGB file.

Exemple :

From HTML :

<form action="#" methode="POST">
<a class="launcher" href="#" data-file_id="1"> launch</a>
</form>

$(".launcher").on('click', function(){

something to do

})

I don't know if it's possible and what I can I do.

Yes, I know that the method is loaded.

But I want to save the grade in my database each time the GGB button is clicked.

For that, I use Ajax in my store_score.js.

Now, I save the score at the end of the exercise. But I need to click on a submit button in my HTML code.

I want to do this directly from GGB Button, after every question.

This is my store_score.js

        $('#submit_button').on('click', function (event) {
          var grade = ggb_applet_container.getValue("grade");
          var numexo = ggb_applet_container.getValue("numexo");
          score = grade/(numexo-1) ;
            let start_time = $(this).attr("data-start_time");
            let exercise_id = $(this).attr("data-exercice_id"); 

            let csrf_token = $("input[name='csrfmiddlewaretoken']").val();
            $.ajax(
                {
                    type: "POST",
                    dataType: "json",
                    data: {
                        'score': score,
                        'numexo': numexo-1,
                        'exercise_id':exercise_id,
                        'start_time':start_time,
                        csrfmiddlewaretoken: csrf_token
                    },
                    url: "../../store_the_score_ajax/",
                    success: function () {

                        alert("Le score de cet exercice est enregistré.") ; 
 
                      
                        }
                }
            );
        }); 

Sorry, but want to know if it's possible : From a ggb button, I want to trigger an Ajax script.

Is it possible ? if yes, how ?

MANY MANY thanks !!!

the variable called numexo is inside my ggb file. My fonction is in the html, JS script :

What is wrong ?
