我目前不熟悉JavaScript,正在学校学习!我正在通过创建游戏来完成一项任务,但是警报不断弹出并提示错误的游戏。每次警告为“您找到一个匹配项!”对于每张卡,但这都不应该发生。在过去的一个小时里,我一直在努力解决这个问题。谢谢
var cards = ["queen", "king", "queen", "king"];
var cardsInPlay = [];
var cardOne = cards[0];
cardsInPlay.push(cardOne);
console.log("User flipped " + cardOne);
var cardTwo = cards[1];
cardsInPlay.push(cardTwo);
console.log("User flipped " + cardTwo);
if (cardsInPlay.length === 2){
cardsInPlay[0] === cardsInPlay[1];
alert("You found a match!");
} else {
alert("Sorry, try again");
}
最佳答案
我认为您希望提出如下条件:
if (cardsInPlay.length === 2 && cardsInPlay[0] === cardsInPlay[1]) {
alert("You found a match!");
}
