Ember 路由器:如何使用 transitionTo [英] Ember router: how to use transitionTo

问题描述

我有一个看起来像这样的链接

I have a link that looks like this

index.html#/calendar/year/month

这是我设置路线的方式:

This is how I set up my routes:

App.Router.map(function() {
    this.resource('calendar', {path: 'calendar/:currentYear/:currentMonth'});
});

App.CalendarRoute = Ember.Route.extend({
  model: function (params) {
    var obj = {
       weeks: calendar.getDaysInMonth(params.currentMonth, params.currentYear),
       currentMonth: params.currentMonth,
       currentYear: params.currentYear
    };
    return obj;
  },
  setUpController: function(controller, model) {
      controller.set('content', model);
  }
});

我可以这样做:

var currentMonth = this.get('content.currentMonth');
var nextMonth = parseInt(currentMonth)+1;
var route = '#/calendar/'
var year = this.get('content.currentYear');
window.location.href= route + year + '/' + nextMonth;

但我想改用路由器.

我试过了:

var router = this.get('target');
router.transitionTo('#calendar/'+year + '/' + nextMonth);

但我收到此错误:

未捕获的错误:断言失败:找不到路由#calendar/2013/5

Uncaught Error: assertion failed: The route #calendar/2013/5 was not found

我也试过:

var router = this.get('target');
router.transitionTo('calendar/'+year + '/' + nextMonth);

但这也给了我一个错误:

But this also gives me an error:

未捕获的错误:断言失败:未找到路线日历/2013/5

Uncaught Error: assertion failed: The route calendar/2013/5 was not found

推荐答案

与我在评论中所说的相反，这实际上可以在不需要嵌套路由的情况下完成，使用 Route#serialize.

Oposite from what I said in the comments, this can actually be done without the need of nested routes, using the Route#serialize.

我制作了这个小提琴(demo here) 与您描述的场景类似:

I've made this fiddle (demo here) with a scenario similar to what you described:

在应用程序中，我存储月份和年份参数

In the application, I'm storing the month and year arguments

window.App = Ember.Application.create({
    title: 'Cool App',
    calendar: { 
        month: new Date().getMonth()+1, 
        year: new Date().getFullYear() 
    }
});

定义路由

App.Router.map(function() {
    this.route("home");
    this.resource('calendar', { path: 'calendar/:year/:month'});
});

在日历路由中，我添加了serialize 方法，将obj 中的属性转换到应用程序中，然后我在setupController 获取 days 属性并设置其内容.

In the calendar route, I've added the serialize method, to translate the properties in obj to the app, then I connected with 3rd party lib in setupController to get the days property and set its content.

App.CalendarRoute = Em.Route.extend({
    activate: function() {
        $(document).attr('title','Events')
    },
    serialize: function(obj) {
        return {
            year: obj.year, month: obj.month
        }
    },
    setupController: function(controller, model) {
        var obj = {
            days: calendar.getDaysInMonth(model.month, model.year),
            year: model.year,
            month: model.month
        };
        controller.set('content', obj);
    }
});

在 Handlebars 中，使用 {{linkTo}} 助手，我将在我的 App 类中定义的 calendar 属性作为参数传递:

In Handlebars, using a {{linkTo}} helper, I am passing the calendar property defined in my App class as the argument:

{{#linkTo calendar App.calendar tagName="li"}}
    <a {{bindAttr href="view.href"}}>
        Calendar
    </a>
{{/linkTo}}

这将生成一个链接到 ~/#/calendar/2013/4
