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：

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.
