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，唯一的问题是只需单击一个按钮即可打开的表单，并且在验证和提交时，没有任何反应。寻找“问题在这里”评论，找出我在哪里调用提交方法。谢谢你的帮助！
注意：我正在使用jstl和jqueryui。

在<form>标记
<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();
});
