I need to prompt the user to enter a series of numbers, or the word "quit". Then, If the user enters a number, add the new number to a running total. And, If the user enters the word "quit" the loop should stop execution. I cant figure what should I do here. Im a beginner. i don't know how to make it work when user enter a word quit
let total = 0;
let number = 0;
do {
total += number;
number = parseInt(prompt('Enter a number: '));
if (number >= 0) {
document.writeln("<p>You entered " + number + "!</p>");
} else {
if (isNaN(number)) {
number = parseInt(prompt('Enter a number: '));
document.writeln("<p>Try again. We are looking for a number!</p>");
}
}
} while (number >= 0)
document.writeln("<p>The total is " + total + "</p>")Use break to stop the javascript loop:
let total = 0;
let number = 0;
do {
total += number;
text = prompt('Enter a number: ');
if (text == "quit") {
break;
}
number = parseInt(text);
if (number >= 0) {
document.writeln("<p>You entered " + number + "!</p>");
} else {
if (isNaN(number)) {
number = parseInt(prompt('Enter a number: '));
document.writeln("<p>Try again. We are looking for a number!</p>");
}
}
} while(number >= 0)
document.writeln("<p>The total is " + total + "</p>")
