you can below:

demo

$("input[name=mon]").on("change", function(){     if(this.value=="time"){         alert("first time : " + $('select[name="firsttime"] option:selected').text());         alert("second time : "+$('select[name="secondtime"] option:selected').text());     }  });

update

for demo trying values on button click:

$('.getval').on('click',function(){     var selectedoption=$("input[name=mon]:checked").val().trim();     if(selectedoption=="time"){         var dispvalue="first time : " + $('select[name="firsttime"] option:selected').text()+ " , second time : "+$('select[name="secondtime"] option:selected').text();         $('.dispselected').text(dispvalue);      }     else     {         $('.dispselected').text(selectedoption + " has been selected");      }  });
