document.getElementById('MyDiv').getElementsByTagName('input')
would give you all input elements in the div with the ID 'MyDiv'.
There's also getElementsByClassName() which can be used in the same
way to filter by classes.
Once you have your checkboxes filtered out one way or the other,
you'll just need to loop through them and set .checked = true.
Hope that helps.
