How to check checkbox with jQuery?

jQuery Notification plugin

The correct way to check checkbox on the DOM elements can be done using jQuery .prop or .attr method.

By using JavaScript’s “checked” property, we can solve the problem directly, instead of manipulating the DOM into doing what we want it to do.

To check checkbox see the below script:

After jQuery version 1.6 you can use:

$('.chkID').prop('checked', true);
$('.chkID').prop('checked', false);

And jQuery version 1.5x and below you can use:

$('.chkID').attr('checked', true);
$('.chkID').attr('checked', false);
