Answer 1

Pseudo code:

function checkAll(array_with_id_values)
{
    for (var i = 0, ilen = array_with_id_values.length; i < ilen; i++)
    {
        document.getElementById(array_with_id_values[i]).checked = true;
    }
}

Call it with:

checkAll(['my-unique-id', 'my-other-unique-id', 'my-third-unique-id']);

You should ofc not use such verbose variable names and do checks that the argument is an array and that the element you get is a checkbox etc etc.

JQuery is great when there's a pattern to match. See Check All Checkboxes with JQuery.
