棱角材料2日期选择器如何配置为在焦点上自动打开？我在https://material.angular.io/components/datepicker/overview的文档中找不到任何内容.
目前的HTML是这样的:
<input [mdDatepicker]="myDatepicker" id="inputWeekEnding" name="inputWeekEnding" type="text" class="form-control" show-button-bar="false"
[(ngModel)]="weekEnding" [mdDatepickerFilter]="weekEndingPickerFilter" (ngModelChange)="weekEndingChanged()"
required>
<span class="input-group-btn">
<button type="button" class="btn btn-default" [mdDatepickerToggle]="myDatepicker">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
<md-datepicker #myDatepicker md-open-on-focus ></md-datepicker>
