jquery javascript question

Question

Hello,

var val = $("#desc").val();   // input box
var val2 = $("#type").val();  // select box
if((val=='') || (val2 == ''))
     {
     alert("err");
     }
else { // codes }

when i select dropdown and not type anything on inputbox, the alert err still comes out?

how to make it when dropdown is selected, it goes to else clause?
