How to get checked checkbox value in javascript?

For multiple checkboxes with same name:

let checkboxes = document.querySelectorAll('input[name="options"]:checked');checkboxes.forEach(cb => console.log(cb.value));

This iterates over all checked checkboxes.

Remember to use event listeners if you want to check values dynamically on change:

checkbox.addEventListener('change', function() {    console.log(this.checked, this.value);});

To get the value of a checked checkbox in JavaScript, use:

let checkbox = document.getElementById('myCheckbox');if (checkbox.checked) {    console.log(checkbox.value);}

This will print the value if the checkbox is checked.
