事件监听器 - 推送方法问题

Question

我用一些条件写了一个简单的事件监听器，奇怪的是数组playerGuess替换了数组allPlayerGuesses，而不是按预期推送。有人能说出我错过了什么吗？

// The cookie needs to be First in the chain.
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationType = "CustomExternal",
    AuthenticationMode = AuthenticationMode.Passive,
    CookieName = "MyAwesomeCookie",
    ExpireTimeSpan = TimeSpan.FromMinutes(5),
    //Additional custom cookie options....
});

//Note that SignInAsAuthenticationType == AuthenticationType
app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions
{
    AuthenticationType = "GoogleBackOffice",
    ClientId = "abcdef...",
    ClientSecret = "zyxwv....",
    SignInAsAuthenticationType = "CustomExternal"
});

Answer 1

我遇到了这个问题。 当你执行allPlayerGuesses.push（playerGuess）时，它不仅会将其插入allPlayerGuesses，还会替换数组中playerGuess的现有值。您可以通过检查allPlayerGuesses的长度来验证这一点。这将在allPlayerGuesses中创建重复的条目。

解决方案是在每次进入点击事件时初始化playerGuess。

这可以解决您的问题。
