$('#drop').change(
    function() {
        var val1 = $('#pick option:selected').val();
        var val2 = $('#drop option:selected').val();

        // Do something with val1 and val2 ...
    }
);

If you have simple dropdown like:

<select name="status" id="status">
    <option value="1">Active</option>
    <option value="0">Inactive</option>
</select>

Then you can use this code for getting value:

$(function(){

 $("#status").change(function(){
     var status = this.value;
     alert(status);
   if(status=="1")
     $("#icon_class, #background_class").hide();// hide multiple sections
  });

});

Try like this

 $("#drop").change(function () {
        var end = this.value;
        var firstDropVal = $('#pick').val();
    });
