jquery javascript question

Question

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?

You need to show us how you're capturing the event...

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

Huh? How do you know he wants && instead of ||? I'm not seeing that implied in the question anywhere.

Such a simple fix I almost missed it the first time I read your solution. Well done.

@T.J. : "when i select dropdown and not type anything on inputbox, the alert err still comes out?". That suggests that when he selects a value in the dropdown and leaves the input empty, he does not want the error to show. I think this is a great pick-up by Salil.
