Question

我使用Bootstrap创建了一个表单，我需要“ partIVAInput”类的输入轮廓变为红色，并且出现红色反馈消息-不仅当输入为空时，而且当它们的值都由“ isValidPIVA（值）”功能-错误。类“ partIVAInput”的输入的“ keyup模糊更改”处理程序检查该值是否存在，并相应地将类“ is / valid / invalid”分配给输入。

由于遇到以下问题，可能我的处理不佳。

当我在字段中插入正确的值（确定）...

当我在字段中插入错误的值（确定）...

当我在字段中使用错误的值提交时（否！！！反馈消息会正确显示，但输入的轮廓已变为绿色，而它必须为红色。同样，如果我输入了新的错误值在该字段中，输入的轮廓继续为绿色。此外，在提交表单时，该字段带有标记为“ is-invalid”（我无效）。

怎么了？
