angular2 submit form by pressing enter without submit button

Question

You can also add (keyup.enter)="xxxx()"

Maybe you add keypress or keydown to the input fields and assign the event to function that will do the submit when enter is clicked.

Your template would look like this

    <form (keydown)="keyDownFunction($event)">
      <input type="text" />
    </form

And you function inside the your class would look like this

    keyDownFunction(event) {
      if (event.keyCode === 13) {
        alert('you just pressed the enter key');
        // rest of your code
      }
    }

Edit:

  <form (submit)="submit()" >
    <input />
    <button type="submit" style="display:none">hidden submit</button>
  </form>

In order to use this method, you need to have a submit button even if it's not displayed "Thanks for Toolkit's answer"

Old Answer:

Yes, exactly as you wrote it, except the event name is (submit) instead of (ngSubmit):

<form [ngFormModel]="xxx" (submit)="xxxx()">
  <input [(ngModel)]="lxxR"   ngControl="xxxxx"/>
</form>

I prefer (keydown.enter)="mySubmit()" because there won't be added a line break if the cursor was somewhere within a <textarea> but not at its end.

This way is much simple...

<form [formGroup]="form" (keyup.enter)="yourMethod(form.value)">

</form>

add this inside your input tag

<input type="text" (keyup.enter)="yourMethod()" />
