为什么不显示元素列表? [英] Why isn't list of elements showing up?

问题描述

我正在编写 AngularJS 教程

I am working on an AngularJS tutorial

本教程介绍了 ng-repeat 指令，这是一个使用重复数据的 AngularJS 指令.

This tutorial covers the ng-repeat directive, an AngularJS directive used repeating data.

为了展示 ng-repeat 的例子，作者以 JSON 格式输入元素周期表元素，包括元素名称、元素 # 等到控制器逻辑($scope)中

To show an example of ng-repeat, The author enters periodic table elements in a JSON format, covering element's name, element #, etc into controller logic($scope)

为了显示元素(下面的代码)，作者简单地使用了带有 html 无序列表的指令

To display the elements(code below), the author simply used the directive with a html un-ordered list

<ul>
  <li data-ng-repeat="element in periodic.elements">{{element.name}} </li>
</ul>

我尝试做同样的 JsFiddle 但元素列表没有显示，只有 {{element.name}}

I tried doing the same JsFiddle but the list of elements isn't showing up, only {{element.name}}

起初我认为这是一个 AngularJS 语法问题，但我检查了 scope 属性，如果控制器名称匹配等等......我确保在 JsFiddle 中也启用了 AngularJS 选项.

At first I thought this was an AngularJS syntax issue but I checked over the scope attribute, if the controller names match, etc.... I made sure to enable the AngularJS option in JsFiddle as well.

有谁知道问题是什么或者为什么这个列表没有出现?

Does anyone know what the issue is or why this list isn't showing up?

推荐答案

你忘记完成控制器语法 '});'在代码的末尾.

You forget completing controller sytax '});' at the end of the code.

'use strict';
var chemistryApp = angular.module('chemistryApp', []);

chemistryApp.controller(
      'chemistryController',
    function chemistryController($scope) {
        $scope.periodic = {elements: [
            {
                "atomicNumber": 1,
                "name": "Hydrogen",
                "atomicWeight": 1.00794,
                "phase": "Gas",
                "ionization": 13.5984,
                "melting": -259.15,
                "boiling": -252.87
            },
            {
                "atomicNumber": 2,
                "name": "Helium",
                "atomicWeight": 4.002602,
                "phase": "Gas",
                "ionization": 24.5874,
                "melting": 0,
                "boiling": -268.93
            },
            {
                "atomicNumber": 3,
                "name": "Lithium",
                "atomicWeight": 6.941,
                "phase": "Solid",
                "ionization": 5.3917,
                "melting": 180.54,
                "boiling": 1342
            }
        ]
       };
    });
