2. Modify the Example 19.8 - new program. [20 points]
A. Use confirm function to always ask if the user wants to continue
before the program ends.
B. If the user click OK button, the program should start again.
C. If the user click Cancel button, then the program ends
and output (alert()) "See you next time" message.
Can you also get rid of the number parts so it is just doing what the question asks
<html>
<head>
<title>JavaScript Sort Program</title>
<script language="javascript">
do{
lc = true;
got = prompt ("Would you like to continue");
answer = confirm ("You input: " + got + ". Is this correct?");
if (answer == true){
var ck = isNaN(got);
if (ck == true)
alert(got + " is not a number");
else{
alert ("Your number squared = " + got*got);
}// end if
} // end if
lc = confirm("Do you want to continue?");
// confirm function will promt the user , if user click ok than it will return true if user click canc than it will return false, so here lc will store the return value
// if it is true than it will continue and it is false loop get terminated after coming out of the loop we will print see you next time using alert() function
} while (lc == true)
alert("See you next time");
