我正在尝试将html表单元素中的注释添加到angularjs中的数组中。当我使用javascipt push函数时，我得到一个错误＆＃34;对象的属性不存在＆＃34;。 有人可以帮我解决这个问题。您可以在下面找到我的javascript和html代码：
感谢您阅读

答案 0 :(得分：0)
我认为它与每个控制器的范围有关。当您的提交函数位于dish.comments控制器中时，您在DishDetailController中定义了DishCommentController。
尝试将submitcomment函数从DishCommentController控制器转移到DishDetailController控制器，因为DishCommentController在其范围内甚至没有$ scope.dish.comments。
编辑：按照建议更新代码后，尝试一下
.controller('DishDetailController', ['$scope', function($scope) {
var $scope.dish ={
name:'Uthapizza',
image: 'images/uthapizza.png',
category: 'mains',
label:'Hot',
price:'4.99',
description:'A unique combination of Indian Uthappam (pancake) and Italian pizza, topped with Cerignola olives, ripe vine cherry tomatoes, Vidalia onion, Guntur chillies and Buffalo Paneer.',

{
rating:5,
comment:"Imagine all the eatables, living in conFusion!",
author:"John Lemon",
date:"2012-10-16T17:57:28.556094Z"
}
...
]
};
$scope.newcomment = {
rating : "",
comment: "",
author: "",
date: new Date().toISOString()
};
$scope.submitComment = function (rating , author, stars, date) {
$scope.dish.comments.push($scope.newcomment);
}
}]);
我删除了一些额外的代码，您可以在以后开始工作时添加这些代码。
<div class="row row-content" ng-controller="DishDetailController">
<div class="col-xs-9 col-xs-offset-1">
<h4>Customer Comments</h4> Sort by:
