Javascript 角度材质设计-将日期对象绑定到MdDatepicker

我从官方页面学习使用Material Design datepicker，我想将choosen数据绑定到日期对象

datepicker-overview-example.component.html：

<md-input-container>
  <input mdInput [mdDatepicker]="picker" placeholder="Choose a date">
  <button mdSuffix [mdDatepickerToggle]="picker"></button>
</md-input-container>
<md-datepicker #picker></md-datepicker>

---

如何绑定它？

方法是将

值

属性绑定到

输入

元素

<md-input-container>
  <input  [value]="value" mdInput [mdDatepicker]="picker" placeholder="Choose a date">
  <button mdSuffix [mdDatepickerToggle]="picker"></button>
</md-input-container>
<md-datepicker (selectedChanged)="selectedChanged($event)" #picker></md-datepicker>

<md-input-container>
  <input  [value]="value" mdInput [mdDatepicker]="picker" placeholder="Choose a date">
  <button mdSuffix [mdDatepickerToggle]="picker"></button>
</md-input-container>
<md-datepicker (selectedChanged)="selectedChanged($event)" #picker></md-datepicker>

value:Date =new Date();
