            var emptyPlace = 0;
            if (userName.length < 2) {
                emptyPlace = 1;
                return emptyPlace
            }
            if (emptyPlace == 0) {
                localStorage.setItem("name", userName );
            localStorage.setItem("entered", 1 );
            window.location = "UserApp/";
            }
            if(emptyPlace == 1){
               alert("text");
            }
            
            

        }

I have trying to give alert while input field is empty. System can understand that field is empty but if(emptyPlace == 1) is not working help me please

CodePudding user response：

You are returning which means your function ends after the return, there is no need to return there.

           if (userName.length < 2) {
                emptyPlace = 1;
                return emptyPlace
            }

Also dont use var, use const and let.

Const and let
