How can i check if user has selected any option from dropdown

[jay123]

Hello,

As title states, i have a DropdDown and i need to stop user submitting form if he hasn't selected anything in Dropdown

i am using (for testing purpose)

alert($("#DivId option:selected").val().length);

and it return 0 if nothing selected and length of selected option (if selected), but when i use same command in If like

 if ($("#DivId option:selected").val().length == 0);
 {
     alert('please choose dropdown 2');
      return false;
 }

this always shows the alert message irrespective of if user has selected anything in Dropdown or not. but first alert shows correct value.

Can somebody please help me where i am going wrong, Its something very minor and frustating.

Any help will be appreciated.

Regards
