$("#btnSubmit1").on("click", function() {
	if($(".status1:checked").val()) {
		alert('checked')
	} else {
		alert('not checked.')
	}
});

 

Method #2

// Method #2 - check using is() function to determine if the radio button is checked
$("#btnSubmit2").on("click", function() {
	if($(".status2").is(':checked')) {

	} else {

	}
});
