您需要在此处使用 Controller as 语法，
<div class="container" ng-controller="dishDetailController as dish">
<强>样本
var app = angular.module('confusionApp',[]);
app.controller('dishDetailController', function() {
var 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.',

答案 1 :(得分：0)
尝试在$scope而不是this设置菜肴对象。
$scope.dish = dish;
答案 2 :(得分：0)
您需要向函数注入$ scope并将var对象分配给$ scope。尝试下面给出的代码。

$scope.dish = dish;

答案 3 :(得分：-2)
错误是你没有用碟子附上一个范围变量。而不是使用this.dish，使它成为$ scope.dish。我已经更新了下面的控制器功能。
app.controller('dishDetailController', function($scope) {
var 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.',

$scope.dish = dish;
