Nested if-statement help – please!

Copy linkTweet thisAlerts:
Jan 31.2004

Hi,

I’m trying to nest an if-statement. I want to quiz the user with the question “What is the capital of Kenya?”. If they get it right, a message congratulating them will be displayed. If they get it wrong, I want to give them one more change. If they still get it wrong, I want to display a message that says “better luck next time”.

Here’s my code so far:

var question = “What is the capital of Kenya?”;
var answer = Nairobi;

var guess = window.prompt(question, “Enter your answer here”);

if (guess == answer) {
window.alert(“CONGRATULATIONS!!!”);
if (guess != answer)
guess = window.prompt(question, “Go on, have another go!”);
window.alert(“Second time lucky! Well done!);
}
else {
document.writeln(“I’m sorry, better luck next time”);
window.alert(“Unlucky mate!”);
}

I can’t get it to work… PLEASE HELP!!

What am i doing wrong?

Thanks ?

@David_HarrisonJan 31.2004 — Not the only problem fred. ?

You did not put quotes around the answer and the logic of your if/else statements needed changing a bit, other than that it was almost there. Just as a good habit to pick up, you might also want to always use {} for your if's and else's.

var question = "What is the capital of Kenya?";
var answer = "Nairobi";

var guess = prompt(question, "Enter your answer here");

if (guess == answer){alert("CONGRATULATIONS!!!");} // End of outside if

else{

guess = prompt(question, "Go on, have another go!");

if(guess == answer){alert("Second time lucky! Well done!");} // End of inside if
else{
alert("Unlucky mate!");
document.writeln("I'm sorry, better luck next time");
} // End of inside else

} // End of outside else

Once you copy and paste this into notepad, the comments should line up and be easier to read.

Edit: I found that you also missed of a closing quote in one of your alerts.

@fredmvJan 31.2004 — Good catch. I didn't really look over the code too much, as you can tell. ?

@london_city_guyauthorJan 31.2004 — Wow - you guys are great!!

Thanks very much.

I'm a novice at this as you can tell.. slowly but surely, i'll get there in the end.. i hope.

I need to do a few more things:

  • - nest a loop within an if-statement


    • and

  • - nest an if-statement within a loop


    • any idea's of how i can start these?

    @buntineJan 31.2004 — Here ya go..

    Loop within an if-statement.
    [code=php]
    if (expression) {
    for (var i=0;i<10;i++) {
    alert("Number: "+i);
    }
    }
    [/code]

    If-statement within a loop:
    [code=php]
    for (var i=0;i<10;i++) {
    if (i <= 5) {
    alert("Variable is 5 or less.");
    } else {
    alert("Variable is greater than 5");
    }
    }
    [/code]

    Regards,

    Andrew Buntine.
