Question

I have a problem with this code:

var buyerChoice = prompt("Enter a either apple, orange, or banana:", "");        

var fruits = new Array ("apple", "orange", "banana");

for(i=0; i < fruits.length; i++) {
    if(buyerChoice === fruits[i]) {
        document.write(buyerChoice);
    } else if (buyerChoice !== fruits[i]){
        document.write("Sorry, " +buyerChoice+ " is out of season.");
        break;
    }
}

I believe the problems lies in the else-if statement because every time I type in an item that exists in my variable, it will return //appleSorry, apple is out of season, thus meeting both conditions.

I’m stumped. I guess the bottom line is how to effectively match a string from a prompt to an array, testing each item and how to parse an array if a prompted string doesn’t exist.

Answer 1

var buyerChoice = prompt("Enter a either apple, orange, or banana:", "");        

var fruits = ["apple", "orange", "banana"];

var outOfSeason = false;
for(fruit in fruits) {
    if(buyerChoice === fruits[fruit]) {
        matched = true;
        break;
    }
}

if(! outOfSeason){
   document.write(buyerChoice);
}
else{
   document.write("Sorry, " +buyerChoice+ " is out of season.");
}
