我正在研究表单验证，经过一段时间我找到了jquery-form-validator插件，这将帮助我验证。但现在我试图找出如何改变错误位置。现在所有错误都显示在字段名称前面。我想在此

中显示电子邮件的错误

<label for="user" generated="true" class="error"></label>

并且还有任何形式验证的PHP

Answer 1

使用属性data-validation-error-msg-container指出某个输入的错误消息的位置

<input data-validation="..." 
       data-validation-error-msg-container="#some-where-else" />
<div id="some-where-else"></div>

在谈到这一点时，你还有其他一些选择。您可以在http://formvalidator.net/#configuration_position

上阅读相关内容

Answer 2

使用可以在此处参考他们的文档http://formvalidation.io/examples/showing-message-custom-area/以获取自定义错误消息区域

或者您可以使用此代码：

err: {
        container: '#messages'
    },

您可以在每个字段的jQuery验证插件代码中尝试此代码。
