consider this general question:

what comes after the letter c in the alphabet

answer is : d.

how can i check to see if the answer is correct or not without using a form, but using the alert,prompt, confirm methods. how would i incorporate the if/else statements

<script>
alert("what comes after the letter c in the alphabet?");
prompt("please enter the correct answer");
confirm("are you sure that is correct?");
if(...)
{
alert("that is correct");
}
else
{
alert("that is not correct");
}
</script>

what am i missing or doing incorrectly?


feedback is greatly appreciated

You have to use a var "chars" into your code, for the client to recognize the alphabet (yes, stupid as it is, a computer does not know the alphabet!)
You also have to assign a variable to the answer.
So your code would be:

<script>
chars="abcdefghijklmnopqrstuvwxyz"
alert("what comes after the letter c in the alphabet?");
answer = prompt("please enter the correct answer","");
confirm("are you sure that is correct?");
reponseEnNombre=chars.indexOf("c",0)
reponseEnNombrePlusUn=(reponseEnNombre+(1*1))*1
if(chars.charAt(reponseEnNombrePlusUn)==answer.charAt(0))
{
alert("that is correct");
}
else
{
alert("that is not correct");
}
</script>


Or you can even make a random letter:
(a little bit harder):


<script>
chars="abcdefghijklmnopqrstuvwxyz"
random=Math.round(Math.random()*chars.length)
letterChosen=chars.charAt(random)
alert("what comes after the letter "+letterChosen+" in the alphabet?","");
answer = prompt("please enter the correct answer");
confirm("are you sure that is correct?");
reponseEnNombre=chars.indexOf(letterChosen,0)
reponseEnNombrePlusUn=(reponseEnNombre+(1*1))*1
if(chars.charAt(reponseEnNombrePlusUn)==answer.charAt(0))
{
alert("that is correct");
}
else
{
alert("that is not correct");
}
</script>
