如何解决vue一个表单下有多个validator时，无法手动校验所有除最后一个validator外的validator?

代码如下，当我把comment填的超过12个字符后，点send按钮还是不会校验comment，但对comment2 却可以。

<div id="app">
    <form novalidate method="post" v-on:submit="submitForm">

            <div class="errors">

                this.$validate("comment", true, function () {

<validator name=""></validator>同一个表单中只需要出现一对就行了，不在一个实例中，怎么同时给你验证嘛~你说对不？
