angular2 submit form by pressing enter without submit button
<p>Is it possible to submit a form that does not have submit button (by pressing enter) 
example : </p>

<pre><code>&lt;form [ngFormModel]="xxx" (ngSubmit)="xxxx()"&gt;
  &lt;input [(ngModel)]="lxxR"   ngControl="xxxxx"/&gt;
&lt;/form
</code></pre>
