Determine if Checkbox is Checked using jQuery [duplicate]

Check checkbox checked property using jQuery

What is the correct way of accessing a checkbox to check if it's checked? Is it necessary to first check if that element exists in the DOM and then see if is checked or not?

@Vega Given an appropriate DOMElement (which must exist), but not the most tidy way in jQuery. — user166390

@pst In the FM doesn't say if I first need to check if the element exists, and that was my doubt. — Hommer Smith

You would use the checked selector along with the is method of Jquery

if($('#chkbox').is(':checked')){

}

You can see if the checkbox is checked by using the following condition.

   if( $("input:checked").length == 1 ) {
           //Checkbox is selected and Do stuff here
       }
