我遇到了循环问题.它循环很好,但是如果我在if语句后移动了guess语句,那么每次都会返回到该语句.如果我把它放在if语句之外,那么它似乎实际上不允许我猜出一个有效的数字.很难解释 :\
我建议只使用一个提示并将其分配给变量.
function guessGame() {
var number = Math.random() * 11 | 0,
guess,
text = 'Guess a number:';
do {
guess = prompt(text);
if (number < guess) {
text = "You've guessed too high!";
} else if (number > guess) {
text = "You've guessed too low!";
}
} while (guess != number);
document.write("Good Job!");
}
guessGame();
