Angular supports this out of the box. Have you tried ngSubmit on your form element?
<form ng-submit="myFunc()" ng-controller="mycontroller">
<input type="text" ng-model="name" />
<br />
<input type="text" ng-model="email" />
</form>
EDIT: Per the comment regarding the submit button, see Submitting a form by pressing enter without a submit button which gives the solution of:
<input type="submit" style="position: absolute; left: -9999px; width: 1px; height: 1px;"/>
If you don’t like the hidden submit button solution, you’ll need to bind a controller function to the Enter keypress or keyup event. This normally requires a custom directive, but the AngularUI library has a nice keypress solution set up already. See http://angular-ui.github.com/
After adding the angularUI lib, your code would be something like:
<form ui-keypress="{13:'myFunc($event)'}">
... input fields ...
</form>
or you can bind the enter keypress to each individual field.
Also, see this SO questions for creating a simple keypres directive:
How can I detect onKeyUp in AngularJS?
EDIT (2014-08-28): At the time this answer was written, ng-keypress/ng-keyup/ng-keydown did not exist as native directives in AngularJS. In the comments below @darlan-alves has a pretty good solution with:
<input ng-keyup="$event.keyCode == 13 && myFunc()"... />
