Hello,
thank you for your attention.
Before version 48 of firefox, I used onclick, in the HTML pages
Despite all the help of the AMOs, I did not understand why, my codes were no longer working.
By dint of reading their messages, and learning what the words used meant. I understood and adapted my codes to the new safety standards.
I have three projects under construction.
The first named lecjoa which allows to generate multidirectional video.
The second lecjo which is an audio plugin, some values in the HTML page generates music.
The third allows artists to create their own virtual musical instrument (sound and form).
My short-term goal is to work as a team. Each bringing his knowledge and his perception of the world. Because on my own, I have the impression that nobody understands what I say.
cordially
P.S. example end of .js 
function fait() {
document.querySelector(‘#filejo’).addEventListener(‘change’, function() {
for (var i = 0; i < this.files.length; i++) {
setupReader(this.files[i]);
}
});
}
/passerelle firefox 48 pour remplacer le bouton d’appel java/
document.addEventListener(“DOMContentLoaded”, function(event) {
fait();
});
/fin passerelle firefox 48/
