Modifying PreSaveAction Function

Question

I currently have a PreSaveAction function that I was given. It currently looks at the people picker field (Reviewer 2) to make sure it is filled before allowing the form to be saved. Is there a way to change it to look at the choice field (Rev2 Required) instead? Here's my script:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script type="text/javascript">
function PreSaveAction(){
    //these look for the display name values in the associated people pickers
    var rev2 = $("input[Title='Reviewer 2']").attr("aria-label");

    if(rev2){
        return true;
    }
    else{
        alert("You must select a person as Reviewer 2. Please refer to the Approval and Payment of Invoices policy for guidelines.");
        return false;
    }
}
</script>

Answer 1

You've to use Select for Choice field.

var choiceFieldValue =  $("select[title$='ChoiceFieldName']").val();

Then check the variable according to your requirement.
