在我的 htm 页面中,我想使用一个按钮,该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的值它刷新我的表单。我只希望我输入的值存在于那里,并且只有错误消息的字段会消失。所有其他字段都保留在那里。 这是我的代码:

最佳答案
如果验证失败,您可以使用此代码来阻止表单提交到服务器:
$("form").on("submit", function(event){
if(!isValidForm($(this)){
event.preventDefault();
}
});
假设 isValidForm() 方法采用表单选择器,如果表单有效则返回 true,否则返回 false。
