Jquery 如果验证不起作用，请尝试注释您尝试验证的字段（消除过程）。例如，注释掉除第一个无效字段之外的所有字段。当它是唯一的字段时，它能工作吗？我去掉了滑块的内容，它工作得很好：您可以看到我是如何使用console.log（）来跟踪和验证值的。我建议你做一些类似的事

如果验证不起作用，请尝试注释您尝试验证的字段（消除过程）。例如，注释掉除第一个无效字段之外的所有字段。当它是唯一的字段时，它能工作吗？我去掉了滑块的内容，它工作得很好：您可以看到我是如何使用console.log（）来跟踪和验证值的。我建议你做一些类似的事情来找出我没有包含在演示中的代码中的问题。如果你将我上面发布的演示链接与你在问题中发布的代码进行比较，你可以看到我遗漏了什么。我不知道这是您的问题的原因还是您的代码中没有显示的其他内容。我确实知道你试图做的验证工作的核心。
