一个简单的直接游戏用户输入 6 个数字并单击按钮播放，如果所有 6 个数字都匹配他们中奖，我已经设置了循环，以便它不断生成随机数直到用户获胜，然后通知他们循环数它需要获得中奖号码。我的逻辑问题是，即使匹配一个数字，循环也会终止，我需要它继续运行，直到所有数字都匹配。这是代码，请帮忙，以便我可以倾斜:)

您需要在 while 循环中有 OR 条件

while(resultnum1 != enterednum1 || resultnum2 != enterednum2 || resultnum3 != enterednum3 || resultnum4 != enterednum4 || resultnum5 != enterednum5 || resultnum6 != enterednum6)

这样，即使一组不匹配，代码也会再次循环！

而且由于您使用的是 Math.random()，因此您将很难验证逻辑，因为您可能需要预测 Math.random() 的结果，很幸运能赢得大奖:)

有时阅读 NOT 逻辑会有点麻烦，尤其是 while 子句依赖于某些东西是真实的来继续继续

为了便于阅读，我尽量让事情保持“真实”

} while( !(resultnum1 == enterednum1 && resultnum2 == enterednum2 && resultnum3 == enterednum3 &&
resultnum4 == enterednum4 && resultnum5 == enterednum5 && resultnum6 == enterednum6) )

编辑：另外，您的 if 语句看起来是复制和粘贴的.. 可能需要修复语句的其余部分

if ( resultnum1 == enterednum1 && resultnum2 == enterednum2 && resultnum3 == enterednum3 && resultnum4 == enterednum4 && resultnum5 == enterednum5 && resultnum6 == enterednum6 ){

编辑2：这是对我有用的代码。它大约在 4 次尝试中起作用，但这只是因为我将随机最大值减少到 6
