udemy-course-reset-for-browser.md

Un/check all visible checkboxes for a course.

Currently only works if course content is visible, and course section(s) is/are already expanded.

Usage:

Open console for web browser (F12 or Right-Click Inspect) Paste the section of JavaScript below into the console according to your needs.

Open Course Content (WIP)

// Activate sidebar menu to expose course sections
const courseContent = document.querySelector("section[data-purpose='open-course-content']");

Expand Course Sections (WIP)

// Find all accordian-panel--???? entries in course sections
const courseSection = document.querySelector("section[data-css-toggle-id='accordion-panel--1097']");
// For each accordian-panel--???? entry in course sections, set the data-checked to "checked"
courseSection.forEach((checkbox) => {
    if (checkbox.checked) {
        checkbox.click();
    }
});

Uncheck all visible checkboxes

const checkboxes = document.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
    if (checkbox.checked) {
        checkbox.click();
    }
});

Check all visible checkboxes

const sectionEl = document.querySelector("section[data-purpose='sidebar']");
const checkboxes = sectionEl.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
    if (!checkbox.checked) {
        checkbox.disabled = false;
        checkbox.click();
    }
});
