can i make this into 1 switch case instead of many if else statements

const ticket = {
                   movie : document.getElementById("movie").value,
                   amount : document.getElementById("amount").value,
               };

This is my object and I want to validate input. But I'm not sure how to change if-else statements to one switch case, since it has different statements.

PS: for learning purpose I need to use javaScript and not jQuery.

if(ticket.movie ===""){
    document.getElementById("warningMovie").innerHTML = "need to choose a movie"
}else{
    document.getElementById("warningMovie").innerHTML = "";
}

if(ticket.amount === ""){
    document.getElementById("warningAmount").innerHTML = "need to choose amount"
}else{
     document.getElementById("warningAmount").innerHTML = "";
}
