问题很少，

(i) 角度材料缺少依赖项 (ii) 正如 Mahesh 所说，您应该在视图中提及 ng-app

演示

angular.module('firstApplication', ['ngMaterial'])
 .controller('openTicketController', openTicketController);
 function openTicketController ($scope) {
     $scope.departments = [
     {id: 1, type: 'IT'},
     {id: 2, type: 'Networking'},
     {id: 3,type: 'Accounts'},
     {id: 4,type: 'Sales'},
     {id: 5,type: 'Support'}
   ];
 }

#inputDiv{
                margin-left: 20px;
                margin-right: 20px;
            }
            .inputCard{
                padding: 5px;
            }

【讨论】：

感谢您的回复，ng-app 在我的主页中。我们必须在 web 应用程序中只给 ng-app 一次。如果我错了，请纠正我。以上对我不起作用。请帮忙
我已经添加了演示检查。你添加了这些引用吗？
是的，我已经添加了这些，但没有得到。如果我在选项标签内提供直接选项，它正在工作，但从脚本不起作用。
办公室无法访问

【解决方案2】：

在 body 标签中包含 ng-app。

<body ng-app="firstApplication" ng-controller="openTicketController">
