i.e, get ids of checkboxes which is not disabled using jquery

I'm assuming your question is "how can I do that thing I just said?", in which case, you can combine the :not and :disabled selectors:

// Get all checkboxes that aren't disabled:
$('input[type="checkbox"]:not(:disabled)')

// Get all selected checkboxes that aren't disabled:
$('input[type="checkbox"]:checked:not(:disabled)')
