我正在创建一个游戏，并且使用单选按钮表单。当用户选择正确答案和错误答案时，我使用 jQuery 设置警报。当用户选择错误答案时，警报会起作用，但当用户选择正确答案时，jQuery 将运行整个脚本。我认为单选按钮中的字符串可能与 Jquery 不匹配，所以我更改了它，但不起作用。我尝试添加变量并进行匹配，但这与其他一些重写不起作用，但我一直遇到同样的问题。我不知道我错过了什么，感谢您的时间和帮助。

最佳答案

您在代码中遇到两个问题，如下所示:

else if (skit === "MADTv", skit === "The Brady Bunch", skit === "Saturday Night Live"); {
    alert("Answer #1 is wrong = In Living Color");
}

  1. 要测试多个条件，应使用 || 分隔它们，而不是 ,。

  2. ; 紧跟在 if(condition) 部分之后。这意味着它后面的 block 不是 if 语句的一部分，而是一个无条件运行的单独 block 。

代码应该是:

else if (skit === "MADTv" || skit === "The Brady Bunch" || skit === "Saturday Night Live") {
    alert("Answer #1 is wrong = In Living Color");
}

但实际上并不需要 else if 条件。只需使用 else，因为您正在匹配所有其他可能性。

else {
    alert("Answer #1 is wrong = In Living Color");
}
