AngularJS Controller depending on URL parameter
提问by billdangerous
EDIT:Added $routeProvider and $routeParams, but $routeParams.productId is always undefined. It was my initial try, but I thought it was the wrong way. Anyway it does not work for the moment.
编辑：添加了 $routeProvider 和 $routeParams，但 $routeParams.productId 始终未定义。这是我最初的尝试，但我认为这是错误的方式。无论如何它暂时不起作用。
I start to learn AngularJS and I have a very simple question : Depending on ID contained in URL, I would like to display different BD record.
我开始学习 AngularJS，我有一个非常简单的问题：根据 URL 中包含的 ID，我想显示不同的 BD 记录。
...
<div ng-app=MyApp>
<div ng-controller="MyCtrl">
{{ record }}
</div>
</div>
...
My Javascript file :
我的 Javascript 文件：
var MyApp = angular.module("MyApp",[]);
MyApp.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/get/:productId', {
controller: 'MyCtrl'
});
}])
MyApp.controller('MyCtrl',['$scope','$routeParams','$http',
function($scope,$routeParams,$http) {
$http.get("/get/"+$routeParams.productId).success(function(data) {
$scope.record = data;
});
}])
I tried to use $routeProvider and $routeParams without success.
我尝试使用 $routeProvider 和 $routeParams 没有成功。
Thank you in advance, Bill

you need 2 things , the $routeParams injected in your controller and create a valid route with the get method
你需要两件事，在你的控制器中注入的 $routeParams 并使用 get 方法创建一个有效的路由
MyApp.controller('MyCtrl',['$scope','$http',"$routeParams",
function($scope,$http,$routeParams) {
$http.get("/get/"+$routeParams.productId).success(function(data) {
$scope.record = data;
});
};
