jQuery - Checkbox Check and Uncheck

There are two ways to check or uncheck checkbox using jQuery
1. The first one by using property

// to check
$('#theCheckbox').prop('checked',true)

// to uncheck
$('#theCheckbox').prop('checked',false)

This sets the property like:

checkboxObject.checked=true;

2. The second one by using attribute

// to check
$('#theCheckbox').attr('checked','checked')

// to uncheck
$('#theCheckbox').removeAttr('checked')
