Question

我正在尝试输出Hello World，但我得到的只是{{“Hello World”}}。这是我第一次使用角度应用程序。谁能告诉我我的代码中缺少什么？我导入了angular.min.js，我在app.js中声明了应用程序并将其附加到html标签，但我仍然无法输出hello world。有什么想法吗？

Answer 1

你的app.controllers名称（bodyController不同）和你的水果列表中有一些语法错误。你需要更加谨慎地使用语法

通过这些改变你可以看到你的hello world


(function() {

    var app = angular.module('app', []);
    app.controller("bodyController", function(){
        this.foods = fruits;
        });
    var fruits = [
        { name: 'Apples', calories: 65, totalFat: '0g', Saturated_Fat: '0g', Cholestrol: '0mg', 
          sodium: '1mg', totalCarbs: '17g', dietaryFiber: '3g', Sugar: '13g', 
          Protein: '0g', vitaminA: '1%', vitaminC: '10%', Calcium: '1%', Iron: '1%'
        },
        { name: 'Oranges', price: 5.95 },
        { name: 'Pineapple', price: 3.95 }
    ];
    })();
