我正在尝试将此表单提交给 servlet，但没有成功。我知道它有一大段代码，但它工作正常，唯一的问题是单击按钮即可打开一个表单，并且在验证并提交后，什么也没有发生。查找“问题在这里”评论以找出我在哪里调用提交方法。谢谢你的帮忙！

注意：我正在使用 jstl 和 jqueryui。

在 HTML 表单代码中添加这个<form>标签

<form action="/someurl" method="post"> 
   <input type="submit" id="btnSubmit" value="Submit Form" />
</form>

如果您想在查看错误后提交，请使用 Jquery

$('form').submit(function(e){
     e.preventDefault(); // prevent from submitting
    //review form errors then submit
    $(this).submit();

});
