通过 AngularJs 创建的对象未出现在网页上

Question

这是我的代码。请告诉我我哪里错了。当我加载网页时，对象盘没有显示。该网页仅保持空白。我正在使用 AngularJs.

Answer 1

ng-init json 对象中缺少 ,：

angular.js:13424 Error: [$parse:syntax] Syntax Error: Token 'description' is unexpected, expecting [}] at column 317 of the expression [dish={name:'Uthapizza', image:'uthapizza.png',

在描述前添加,

price:'4.99',
description:'A unique combination of ....

旁注：

使用 ng-init 可以用于测试目的，但稍后考虑使用 controller instead. See AngularJS ng-init docs:

This directive can be abused to add unnecessary amounts of logic into your templates. There are only a few appropriate uses of ngInit, such as for aliasing special properties of ngRepeat, as seen in the demo below; and for injecting data via server side scripting. Besides these few cases, you should use controllers rather than ngInit to initialize values on a scope.

这里的 plnkr 工作得很好

                <div class="media-left media-middle">
                    <a href="#"><img class="img-thumbnail media-object" ng-src={{dish.image}}></a>
