我正在使用 jquery 进行表单验证，所有字段都工作正常，但只是checkbox并且radio button没有验证，并且将检查两个单选按钮我应该怎么做，任何人都可以根据我的代码向我建议问题出在哪里。如果表格中有任何错误，请随时告诉。

</div>问题是您单独验证所有复选框和单选按钮，而很明显您将它们放在一起考虑：1 个单选按钮的有效性取决于另一个单选按钮的检查属性。
为了解决这个问题，您需要创建一个验证函数来计算属于一起的所有单选按钮，并将检查的属性计数为 1。
更改单选按钮和复选按钮的 HTML，使其具有一个包装类：
<div class="detail gender">
span class="inputBar"></span><!--inputBar-->
<input type="radio" value="male" name="gender" />Male
<input type="radio" value="female" name="gender" />Female
<span class="error">This field is required</span>
</div><!--detail-->
请注意包装单选按钮的“性别”类。还要注意两个单选按钮如何具有相同的名称（这将在浏览器中将单选按钮组合在一起，即如果您选择一个，它将取消选择另一个）。当为“性别”字段提交时，value 属性将与表单一起发送。
现在，您可以通过在给定时间执行此操作来验证这些按钮中的至少一个是否已验证（例如在单击事件中或可能在提交表单时）
var radiobuttons = $(".gender").find("input[type=radio]");
if(radiobuttons.prop("checked").length === 1) {
// do valid stuff here
} else {
// do invalid stuff here
}
这也适用于复选框。
