我想将一个对象推送到数组。但是它没有发生。我在提交单击时将对象注释（表单的值）推送到dishDetailController的dish.comments。
ng-controller =“ DishCommentController”嵌套在ng-controller =“ dishDetailController”内
我要去哪里错了？
main.html
<div class="row row-content" ng-controller="dishDetailController as menuCtrl">
<div class="col-xs-12">
<ul class="media-list">
<li class="media">
<div class="media-left media-top">

最佳答案
如果我没记错的话，那么您将不会创建变量$scope.dish，而只能创建变量var dish = ...，因此您将无法分配任何内容;-)
关于javascript - 将对象推送到无法在Angular JS中工作的数组，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/34979764/
