Javascript Push和forms在AngularJS中

我面临着这个问题，我有一个表格在下面，一些评论是作为列表块报价在我的网页上。我想做的是实时预览我在3个字段中写的内容，在我的表单上方需要两个字段，并与相同格式的其他注释对齐。评论包括名称、评级、评论和日期。所有这些都必须用Angular Js来完成。我面临的问题是，在我的

app.js

文件中，我有4个控制器，我在

dishcomentcontroller

中的一个字段中写入的内容无法放入

dishcomentcontroller

中的数组中。我也不知道如何设置当前日期

我的html代码格式如下：

<div class="col-xs-9 col-xs-offset-1" ng-controller="DishCommentController">
                <ul class="list-unstyled">
                    <li>

                      <blockquote>

                        <p><span ng-show="commentForm.$valid && !commentForm.$pristine">{{ userFeedback.userComment }}</span></p>

<footer>{{userFeedback.userName}}</footer>

                      </blockquote>    
                    </li>
                </ul>
            <form class="form-horizontal" name="commentForm"
                    ng-submit="submitComment()" novalidate>
                <!--task1-creating the form-->

                <div class="form-group" 
                     ng-class="{ 'has-error' : commentForm.firstname.$error.required && !commentForm.firstname.$pristine }"><!-- Task2:Angular validation with red color with the first control:"nameofForm.nameofField.$error.required" and the second control:"!nameofForm.nameofField.$pristine if user touched the form but didn't type anything. -->

嗨，欢迎来到苏。你能修改一下代码格式吗？另外，为什么不能将`放入DishDetailController

中的数组中？（很抱歉，这不是我的专长，但我想你可能会出错？那是什么？）我也不知道如何设置当前日期。`-这是一个完全不同的问题，可能在博客圈的某个地方有答案。谢谢你的回答，但我找到了解决方案……我没有在控制器中嵌套，这就是为什么我无法得到我想要的结果……然而，代码的格式是固定的？我是新的，所以我想知道未来的问题或答案…谢谢，是的，新的格式看起来很棒，谢谢。对于未来，这是一个很好的参考；）
