功能:
用户根据猜谜游戏输入颜色。当答案错误时提示会保持提示，只有当用户设置正确答案时提示才会退出。
我做了什么: 使用 while 循环来检查条件。 while循环中，设置while循环只有等于target时才结束，target是系统随机选取的颜色
问题: 提示最初将颜色设置为答案，但即使用户设置了正确答案，提示仍然循环。
当其中一种颜色设置后如何退出循环？

尝试这段代码，如果输入与目标相同，则控制每一轮循环，如果它们相同，则完成为 true:
function do_game() {
var color = ["blue", "cyan", "gray", "green", "magenta", "orange", "red", "white", "yellow"];
var guess_input_text, guess_input, finished = false,
target, guesses = 0;
var rnd = Math.floor((Math.random() * 9) + 0); //Makes a random number between 0 and 8
target = color[rnd]; //sets the target to a random color from the color array
while (!finished) {
guess_input_text = prompt("I am thinking of these colors:" +
"\n\n blue, cyan, gray, green, magenta, orange, red, white, yellow" + "\n\n what color am I thinking of?"); //gets alert-input from user
guesses += 1;
if(guess_input_text == target){//checks if input from user and target are the same
finished = true;
}
}
}
关于javascript - 即使条件满足后，while 循环也不会停止，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34172221/
