Why doesn't this code work?

Question

This is pretty much what my code is like:

window.onload = alert("message");

var Main = prompt("Choose ONE or TWO").doUpperCase();

var ChoiceOne = alert("Correct");

var ChoiceTwo = alert("Incorrect");

Main;

case(one) {

ChoiceOne;

}
case(two) {

ChoiceTwo;

}

Html and Css are both completely empty. When I run this, nothing happens at all. Can someone please tell me how to fix this?

Answer 1

Turn your main portion into a function

Answer 2

There are too many issues with what you have here, so i'm just gonna post code that does what I think you're trying to do and if you have any further questions after reviewing and comparing the differences between the two just ask them here in this thread.

window.onload = alert("message");

var ans;

var Main = function() { ans = prompt("Choose ONE or TWO").toUpperCase() };

var ChoiceOne = function() { alert("Correct") };

var ChoiceTwo = function() { alert("Incorrect") };

Main();

switch(ans) {
case "ONE": {
ChoiceOne();
break;
}
case "TWO": {
ChoiceTwo();
break;
}
}

Or:

window.onload = function() {
alert("message");

var Main = prompt("Choose ONE or TWO").toUpperCase();

var ChoiceOne = function() { alert("Correct") };

var ChoiceTwo = function() { alert("Incorrect") };

switch(Main) {
case "ONE": {
ChoiceOne();
break;
}
case "TWO": {
ChoiceTwo();
break;
}
}
};
