Angular JS 中的错误在浏览器中将预览显示为 {{dish.comment}}？

Question

I am trying to do an assignment on angular . It was working fine , then suddenly in the brackets preview , i am seeing {{dish.comment}} . I am a newbie. Everything seems to be fine in the file though.Below is the HTML file

<div class="row row-content" ng-controller="DishDetailController">
        <div class="col-xs-12">
            <div class="tab-content">


            <li class="media">
                <div class="media-left media-middle">
                    <a href="#">
                    <img class="media-object img-thumbnail"
                     ng-src={{dish.image}} alt="Uthappizza">
                    </a>
                </div>
                <div class="media-body">
                    <h2 class="media-heading">{{dish.name}}
                     <span class="label label-danger">{{dish.label}}</span>
                     <span class="badge">{{dish.price | currency}}</span> </h2>
                    <p ng-show="showDetails">{{dish.description}}</p>
                    </div>

                   </li>
                  </div>
                  </div>
                  </div>

Below is the App.js file

angular.module('confusionApp', [])
.controller('DishDetailController', ['$scope', function($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;

    }])

And i have included ng-app="confusionApp" in the HTM tag and also included scripts/app.js at the bottom

Answer 1

 angular.module('confusionApp', []) .controller('DishDetailController', ['$scope', function($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.', comments: [ { rating:5, comment:"Imagine all the eatables, living in conFusion!", author:"John Lemon", date:"2012-10-16T17:57:28.556094Z" }, { rating:4, comment:"Sends anyone to heaven, I wish I could get my mother-in-law to eat it!", author:"Paul McVites", date:"2014-09-05T17:57:28.556094Z" }, { rating:3, comment:"Eat it, just eat it!", author:"Michael Jaikishan", date:"2015-02-13T17:57:28.556094Z" }, { rating:4, comment:"Ultimate, Reaching for the stars!", author:"Ringo Starry", date:"2013-12-02T17:57:28.556094Z" }, { rating:2, comment:"It's your birthday, we're gonna party!", author:"25 Cent", date:"2011-12-02T17:57:28.556094Z" } ] }; $scope.dish = dish; }])

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div class="row row-content" ng-app="confusionApp" ng-controller="DishDetailController"> <div class="col-xs-12"> <div class="tab-content"> <li class="media"> <div class="media-left media-middle"> <a href="#"> <img class="media-object img-thumbnail" ng-src={{dish.image}} alt="Uthappizza"> </a> </div> <div class="media-body"> <h2 class="media-heading">{{dish.name}} <span class="label label-danger">{{dish.label}}</span> <span class="badge">{{dish.price | currency}}</span> </h2> <span>{{dish.comments[0].comment}}</span> <p ng-show="showDetails">{{dish.description}}</p> </div> </li> </div> </div> <!--<div ng-repeat="comment in dish.comments"> <p> {{comment.comment}} </p> </div> --> </div>

See comments is array of object so you need to iterate or you can get specific value by using {{dish.comments[0].comment}}

I hope it will solve your problem
