php – 不想刷新并保留最后插入的值

在我的htm页面中,我想使用一个按钮,通过使用函数提交我的表单.我在我的字段上使用验证,当我按下提交按钮时,它显示错误消息,但不保留最后一个值,它刷新我的表单.我只是希望我输入的值将存在于那里,只有只有错误消息的字段才会消失.所有其他领域仍然存在.
这是我的代码：

</html>

请指导我,我该怎么做？我会感谢你的

如果验证失败,您可以使用此代码阻止表单提交到服务器：

$("form").on("submit",function(event){
  if(!isValidForm($(this)){
    event.preventDefault();
  }
});

假设isValidForm()方法接受表单选择器,如果表单有效则返回true,否则返回false.
