我最近一直在开发一款Simon says游戏，如果你点击正确的按钮，它会增加分数，1( 绿色12( 红色23( 特技
我注意到，当我运行游戏并点击适当的按钮时，只有一个会添加到分数中，而其他两个会从中减去(不管声明怎么说(。我不确定为什么会这样，我想知道是否有人有任何见解(。我的想法是if函数似乎与生成的新语句不相关。
任何建议都将不胜感激，
var answers = [
"Simon says click red !",
"Simon says click green !",
"Simon says click 1 !",
"Simon says click 2 !",
"Click green",
"Click red",
"Click 1",
"Click 2!"
];
var score = 0;
var total = document.getElementById("score");
var statement = document.getElementById("instruct");
var randomStatement = answers[Math.floor(Math.random() * answers.length)];
function refresh(){
var randomStatement = answers[Math.floor(Math.random() * answers.length)];
statement.innerHTML = randomStatement;
}
function pressTrick(){
if(randomStatement === "Click green" || randomStatement === "Click red" || randomStatement === "Click 1" || randomStatement === "Click2!"){
score++;
total.style.color = "green";

</html>只有一个词太多了：var。在中
function refresh(){
var randomStatement = answers[Math.floor(Math.random() * answers.length)];
statement.innerHTML = randomStatement;
}
var导致定义新的局部变量randomStatement，而全局randomStatement保持不变，因此程序其余部分中的所有比较都使用randomStatement的初始值，而不是刷新值。将var放在此处，它将按预期工作。
