首先，我真的希望每个人的理解和宽容。这个问题非常具体，所以请不要激进主义/投票/暂停投票。我们都在这里学习新知识并分享知识，而不是侵略。非常感谢。
问题：我正在尝试关注this example，但这似乎没有在Chrome中显示任何内容。 The link显示了预期的结果。我得到的只是浏览器中的空白页面。谁能说清楚为什么？

答案 0 :(得分：2)
更改此
.module('autocompleteDemo', ['ngMaterial'])
到这个
.module('myapp', ['ngMaterial'])
您指定的名称必须与您在ng-app（在您的案例中为myApp）中放置的名称相匹配
答案 1 :(得分：1)
似乎您错过了添加ngMaterial.js的引用，您需要在angular.min.js文件文件引用后添加它。从this cdn获取它，同时添加CSS以使样式正常工作。
答案 2 :(得分：1)
您使用角度材质，但不导入它。我根据angular material getting started page更新了您的依赖项，我创建了一个plunker来验证这一点。
