google recaptcha 验证不适用于 jquery 表单验证器

Question

我的问题：

我有一个注册表单作为 Codeigniter 中的一个视图，我已经使用 Jquery 表单验证对其进行了客户端验证。表单验证对我来说工作得很好。

但是，我在使用此表单时遇到以下问题：

1.Recaptcha 验证： 我在此表单中有一个链接复选框，允许用户填写更多详细信息并上传他的公司徽标。当用户单击此复选框时，jquery 代码只需添加一个文本框和一个文件上传选项来上传公司徽标。（请参阅我的 jquery 代码以在用户选中复选框时添加链接元素）强>

如果用户没有点击这个复选框，并且填写了所有的输入字段并且没有选择recaptcha验证，然后按下提交按钮，jquery表单验证器会抛出一个错误信息并提示用户选择recpatcha验证。

但是，当用户点击链接选项复选框，填写所有输入字段而不选择重新验证验证并按下提交按钮时，页面只是刷新而不给出错误消息。如果用户没有选择 recaptcha 验证，jquery 表单验证器最好抛出错误消息并禁止提交页面。

只有当用户选中链接复选框时才会出现问题。

2.条款和条件复选框验证：

如果用户没有点击链接复选框选项，填写所有输入字段而不点击该复选框，然后按下提交按钮，jquery表单验证器会抛出错误消息并提示用户选择条款和条件复选框。

但是，当用户选中链接复选框，填写所有输入字段（包括重新验证验证），但未选中条款和条件复选框，然后按提交时，页面只会刷新而不会引发错误消息. 理想情况下，jquery 表单验证器应该抛出一个错误提示用户检查条款和条件复选框。

对此问题的任何帮助将不胜感激。

我的研究： 我在 Stack Overflow 上解决了以下问题：

1.reCaptcha v2 in conjunction with jQuery-Form-Validator

2.New reCaptcha with jQuery Validation Plugin

3.how to test Recaptcha with jQuery Validate plugin

Answer 1

解决方案：

我发现jquery表单验证器文件上传的扩展方法是问题的根源。使用时，表单验证器不会在未检查条款和条件复选框和/或 google recaptcha 验证时引发错误。

当我在 Jquery 表单验证器中使用 add 方法将该方法替换为自定义方法文件扩展时，问题得到了解决。表单正在得到验证，并在未检查条款和条件复选框和/或 google recaptcha 验证时引发错误。

我的最终 Jquery 代码：

$("form[name='frmempsignup']").validate(
