Question

我正在尝试使用日期函数在Ember中声明属性，但它没有显示。没有错误但没有数据。我今天跑=新约会（）; ＆安培;和getFullYear（今天）;在控制台中，但它回来时“未完成”。我无法使用这些函数来建模我的数据。怎么了？

<body>
<script type="text/x-handlebars" data-template-name="application">
    <div id="navbar">
       <ul>
        <li>{{#link-to "calendar"}}Calendar{{/link-to}}</li>
        <li>{{#link-to "about"}}About{{/link-to}}</li>
      </ul>
    </div>
    <div id="content"> {{outlet}} </div>
    <footer id='container'>Footer information here!</footer>   

  </script>
  <script type="text/x-handlebars" data-template-name="about">
    <h1>About</h1>
    <p>My calendar Date picker!</>
  </script>
  <script type="text/x-handlebars" data-template-name="calendar">
    <h1>Calendar Page</h1>
    <button>Next</button>
    <button>Today</button>
    <button>Back</button>
    <hr>

        {{today}}

    <hr>
  </script>
</body>

var App = Ember.Application.create({
    LOG_TRANSITIONS: true
});

App.Router.map(function() {
    this.resource('calendar');
    this.resource('about');        
});

App.IndexRoute = Ember.Route.extend({
    redirect: function(){
        this.transitionTo('calendar');
    }
});

App.CalendarRoute = Ember.Route.extend({
    model: function(){
        return App.CalendarData;
    },
    serializer: function(model){
        return {month: model.get('Today')};
    }
});

// calendar controller


// calendar data
App.CalendarData = Ember.Object.extend({
    today: function(){
        var Today = new Date();
        return Today;
    }.property(),

    date: function(today){
        var Date = Today.getDate();
        return Date;
    }.property(),

    month: function(Today){
        // this array gives month names
        var MonthA = new Array();
        MonthA[0] = "January";
        MonthA[1] = "February";
        MonthA[2] = "March";
        MonthA[3] = "April";
        MonthA[4] = "May";
        MonthA[5] = "June";
        MonthA[6] = "July";
        MonthA[7] = "August";
        MonthA[8] = "September";
        MonthA[9] = "October";
        MonthA[10] = "November";
        MonthA[11] = "December";
        var Month = Today.getMonth();
        return MonthA[Month];
    }.property('month'),

    dow: function(Today){
        var Weekday = new Array();
        Weekday[0] = "Sunday";
        Weekday[1] = "Monday";
        Weekday[2] = "Tuesday";
        Weekday[3] = "Wednesday";
        Weekday[4] = "Thursday";
        Weekday[5] = "Friday";
        Weekday[6] = "Saturday";
        var dow = Today.getDay();
        return Weekday[dow];
    }.property(),

    year: function(Today){
        var Year = Today.getFullYear();
        return Year;
    }.property()

});

我不知道你在哪里得到了如何计算属性的例子，但是你可能想查看有关计算属性的指南。

today: function(){
    var today = new Date();
    return today;
}.property(),

date: function(){
    var date = this.get('today').getDate(); // grab the computed property `today`
    return date;
}.property('today'), // this says, when today computed property changes, you should mark this property as dirty

日期功能不作为属性
