我有一个 SPA，需要根据用户所在的路线位置显示不同的 header 。看起来我的代码应该可以工作，但它会产生如下错误: TypeError: undefined is not a function
我在这里缺少什么: html
<html lang="en" ng-app="configApp">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<!--<meta name="viewport" content="width=device-width, initial-scale=1">-->
<title>Configuration Admin</title>
<!-- Bootstrap CSS -->
<link href="_/css/bootstrap.css" rel="stylesheet">
<link href="_/css/main-styles.css" rel="stylesheet">
</head>
<body>
<div class="container">
<!-- Header-->
<div class="row">
<!-- Header to be shown when a program is edited-->
<div ng-include="'templates/headers/nav-icons.html'" ng-if="showNavIcons"></div>
<!-- Header to be shown when Dashboard view-->
<div ng-include="'templates/headers/nav-logo.html'" ng-if="hideNavIcons"></div>
</div> <!-- end header -->
</div>
<!-- Scripts -->
<script src="_/js/bootstrap.js"></script>
<script src="_/js/main-scripts.js"></script>
<script src="_/js/angular.min.js"></script>
<script src="_/js/angular-route.min.js"></script>
<script src="_/js/ui-bootstrap-tpls-0.11.0.min.js"></script>
<script src="_/js/router.js"></script>
</body>
</html>
JS
var configApp = angular.module("configApp", ['ngRoute','ui.bootstrap'])
.config(function($routeProvider){
$routeProvider.when('/dashboard', {
templateUrl: 'templates/dashboard/home.html'
// controller: 'HomeController'
})
.when('/organizations', {
templateUrl: 'templates/dashboard/organizations/organizations-title.html',
controller: 'OrganizationController',
activetab: 'organizations'
})
.when('/program-details-edit', {
templateUrl: 'templates/dashboard/organizations/programs/program-details-edit.html',
controller: 'ProgramDetailsEdit'
})
.otherwise( {redirectTo: '/dashboard'} );
});
// Side Nav Link Controllers
configApp.controller('OrganizationController', function($scope) {});
configApp.controller('SideNavCtrl', function($scope, $location) {
$scope.isActive = function(route) {
return route === $location.path();
}
});
configApp.controller('ProgramDetailsEdit', ['$scope', '$location', '$route', function($scope, $route, $location) {
$scope.showNavIcons = $location.path() === '/program-details-edit';
}]);
configApp.controller('OrganizationController', ['$scope', '$location', '$route', function($scope, $route, $location) {
$scope.hideNavIcons = $location.path() === '/organizations';
$scope.$route = $route;
}]);
最佳答案
您需要将 Controller 添加到元素中。 “ng-controller='controllerName'”作为属性。就类型错误而言，它是未定义的，但是如果您这样做...!!变量，则未定义将变为假。
编辑:
<div class="row" ng-controller="ProgramDetailsEdit">
<!-- Header to be shown when a program is edited-->
<div ng-include="'templates/headers/nav-icons.html'" ng-if="!!showNavIcons">
</div>
ng-controller 将使 div 内部的 dom 能够访问它放入您设置的 $scope 变量中的所有内容。
作为旁注，您应该查看 UI-Router https://github.com/angular-ui/ui-router
它比 $routeProvider 更容易、更强大，您可以按照以下方式做一些事情...
<div class="row" ng-controller="appController">
<!-- Header to be shown when a program is edited-->
<div ng-include="'templates/headers/nav-icons.html'" ng-if="state.name == 'programEditor'">
</div>
