如何调用路由匹配时AngularJs功能？ [英] How to call a function in AngularJs when route matches?

问题描述

$routeProvider.when('/ticket', {
    controller: TicketController, 
    templateUrl: Routing.generate('ticket_list')
});

显示一个简单的列表，其中每个条目是可选的。但是在选择没有多余的看法是加载。每一件事情是 ticket_lost模板。该模板有一些隐藏的字段被点击进入时显露。

displays a simple list where each entry is selectable. However on select no extra view is loaded. Every thing is in ticket_lost template. The template has some hidden fields that are revealed when entry is clicked.

我可以定义通过设置该条目内部选择

I can define which entry is selected internally by setting

selectedTicket = 1;

所以，当有一个像

So when there is a route like

/ticket/1

我想打电话给那台selectedTicket到1之间的功能是可能的吗？怎么做？我有什么路由改变？

I want to call a function that sets selectedTicket to 1. Is that possible? How to do that? What do I have to change in routing?

推荐答案

看看 $ routeParams 服务。
它允许建立与路线将由服务解析参数：

Take a look at $routeParams service. It allows to set up route with parameters which will be parsed by service:

// Given:
// URL: http://server.com/index.html#/ticket/1
// Route: /ticket/:ticketId
//
// Then
$routeParams ==> {ticketId:1}

在你的控制器：

angular.module('myApp')
    .config(['$routeProvider', function($routeProvider) {
        $routeProvider.when('/ticket', {controller: 'TicketController'});
        $routeProvider.when('/ticket/:ticketId', {controller: 'TicketController'});
        $routeProvider.otherwise({redirectTo: '/ticket'});
    }])
    .controller('TicketController', function ($scope, $routeParams) {
        var init = function () {
            if ($routeParams.ticketId) {
                $scope.ticketSelected($routeParams.ticketId);
            }
        };

        // fire on controller loaded
        init();
    });
