JS-файл не загружается в HTML

Question

По какой-то причине BoostOdds.js перестал загружаться для моего HTML, код jQuery в том же файле, BoostOdds.js, работает, так что я полностью потерян, как это вообще возможно?

Посмотрите на кнопку «Переключить все», чтобы увидеть, работает ли jQuery, и все остальные кнопки, чтобы увидеть, работает ли JS.

Index.html 

&

BoostOdds.js

Находятся в одном каталоге.Вот код, спасибо за помощь:

function oneElmToggle(elm) {
  const display = elm.nextSibling.style.display;
  if (display === "none" || display === "") {
    elm.nextSibling.style.display = "block";
  }
  else {
    elm.nextSibling.style.display = "none";
  }
}
window.onload = function () {
  $("#toggleAllElms").click(function () {
    $(".toggleAcronym").toggle('fast');
  });
};

Я вижу, что jQuery не работает в этом фрагменте, но он работает в моем проекте, поэтому мой главный вопрос - как заставить JS работатьв моем проекте тоже.Спасибо.

ОБНОВЛЕНИЕ: Структура папок:

CODE //Project folder
 - css
 - node_modules
     - jQuery npm (Pseudo for loads of folders and files)
 - Principles
     - IntPrin
          - BoostOdds.js
          - index.html
 - scss
 - index.js //Main/Starting, server is set up here
 - package.json
 - package-lock.json

Answer 1

jQuery работает, но не oneElmToggle Почему вы тогда используете vanila JS для этой функции?Используйте JQuery подход.Это компактно и проще:

// there is no need for inline onclick="oneElmToggle(this)" on every button
// and inline JS in no-no

$("#p1136Acronyms > button:not(#toggleAllElms)").click(oneElmToggle)
             // all buttons exept one with id="toggleAllElms"

function oneElmToggle() {
  $(this).next().toggle('fast')
       // nextSibling
}

window.onload = function() {
  $("#toggleAllElms").click(function() {
    $(".toggleAcronym").toggle('fast');
  });
};
