Get the value of checked checkbox?

May 25, 2022 by IT Nursery

So I’ve got code that looks like this:

<input class="messageCheckbox" type="checkbox" value="3" name="mailId[]">
<input class="messageCheckbox" type="checkbox" value="1" name="mailId[]">

I just need Javascript to get the value of whatever checkbox is currently checked.

EDIT: To add, there will only be ONE checked box.
