【问题标题】：Validate multiple forms in sequence with jquery使用jquery按顺序验证多个表单
【发布时间】：2020-05-16 20:17:46
【问题描述】：

我正在尝试逐步验证各种表格。我有 3 个表格。我能够让第一个表单显示，其余的隐藏。当我单击“下一步”显示下一个表单时，第一个表单消失了，但下一个表单不会显示。请指教我做错了什么。这是我的代码 HTML

我认为提供我要模拟的内容的 url 会有所帮助，我将代码从 1 个表格和 3 个图例更改为 3 个表格，每个表格都有自己的图例。 jsfiddle 网址：jsfiddle url of what I want to achieve 任何和所有的帮助将不胜感激。谢谢。

【解决方案1】：

尝试从评论中指出您的问题的问题，但我想没有足够的空间来总结它。

您打算做的事情被认为是一种不良做法并滥用了表单的使用。每个表单通常都有自己的提交按钮并拥有自己的任务（或业务逻辑），因此一旦您点击提交按钮，数据就可以发送到服务器进行处理。您会希望在提交时刷新您的页面并将其重定向到其他地方。这就是为什么我们总是希望每个页面都有一个表单并防止重复提交。

如果您注意到提供的 url，来自所有 3 个面板的数据都包含在一个帐户创建表单中。所有数据将一次发送到服务器并进行验证。按钮有很多，但按钮类型不同。如果在此过程中出现问题，用户始终可以从头开始。

简而言之，表单 -> 服务器。

如果您将它们分成三个表单（甚至将每个表单放在自己的页面中），那么就会出现很多安全漏洞。

form1->server（通过验证，帐户已创建），form2 由于任何原因（互联网问题等）以某种方式失败。现在用户很难回到第 1 步，因为帐户已创建，您是否必须创建另一个块才能完全解决这个混乱。更不用说您试图将三个具有相同意图的表格放在一个页面中，这对您的情况来说是无法挽救的。

【讨论】：

你是对的。我将回到使用一个表单，并将其拆分为 3 个字段集，并在每个步骤中进行验证。感谢您的反馈。
