Q:

Javascript alerts not matching radio form button

I'm creating a game and I'm using the radio button form. I set up alerts using jQuery when the user chooses the correct answer and wrong answer. The alerts work when the user picks the wrong answer but when the user selected the correct answer the jQuery will run through the entire script. I thought maybe the string from the radio button wasn't matching with the Jquery so I changed it and that didn't work. I tried to add variables and having those match and that didn't work along with few other rewrites but I keep running into the same problem. I have no clue what I'm missing, thanks for the time and help.

var skit = "In Living Color";
var girlPower = "Spice Girls";
var boyBand = "AJ, Brian, Nick, Kevin & Howie";
var tvShow = "Martin";
var nba = "Chicago Bulls";
var nfl = "New Orleans, Superdome";
var film = "Titanic";

window.onload = function() {
    event.preventDefault();
    $('#Container').hide();
    $('#start-btn').on('click', function() {
        $('#Container').toggle();
        $('#Intro').hide();
        $('#Score').hide();
        console.log("Quiz has started!");
    });
    $('#submit-btn').on('click', function() {
        Validate();
    })
    function Validate () {
        var skit = $('input[name = "skit"]:checked').val();
        console.log("skit!!", skit);

A:

You have two problems in code like this:
else if (skit === "MADTv", skit === "The Brady Bunch", skit === "Saturday Night Live"); {
    alert("Answer #1 is wrong = In Living Color");
}

To test multiple conditions, you should separate them with ||, not ,.
You have ; immediately after the if(condition) part. This means that the block after it is not part of the if statement, it's a separate block that runs unconditionally.

The code should be:
else if (skit === "MADTv" || skit === "The Brady Bunch" || skit === "Saturday Night Live") {
    alert("Answer #1 is wrong = In Living Color");
}

But there isn't really any need for the else if condition. Just use else, since you're matching all the other possibilities.
else {
    alert("Answer #1 is wrong = In Living Color");
}
