Angular 2 Material Datepicker Value

问题

I want to use Angular Material Datepicker to get a date into my page. I use this code, but cannot figure out how to access the selected value correctly.

<md-input-container>
  <input mdInput [mdDatepicker]="myDatepicker">
  <button mdSuffix [mdDatepickerToggle]="myDatepicker"></button>
</md-input-container>
<md-datepicker #myDatepicker></md-datepicker>

I tried the [value] field in input but how can I get the date to send it to my backend? Thanks.

You can access the datepicker value by using ngModel. The ngModel needs to be in the input tag. See the Plunker demo.

回答2:

as stated in the docs there are 2 events (dateChange) and (dateInput) that can be used if you prefer. the $event has 3 props, target is the MatDatepickerInput, targetElement for the native HTML Element, and value which is the Date object.

<input matInput [matDatepicker]="pickerFrom" placeholder="From" 
      (dateChange)="changeFunc($event)"      <<---- you can send $event
      (dateChange)="dateInput($event.value)" <<---- or just $event.value

As Nehal said, you can use the [(ngModel)] binding; I also forgot the "name" atribute:

  <md-form-field>
    <input mdInput [(ngModel)]="myDateValue" name="myDate"
      [mdDatepicker]="picker" placeholder="Select a date">
