How to submit form with enter press in html textarea

Issue

I want to submit form as soon as I hit enter in the text area, this was working fine with input type text but, I don't know how to do it with text area. I have to use text area as I want text input to be expandable, how can I make it work? Thanks

<div ng-app="myApp" ng-controller="myCtrl">
    <form ng-submit="sendMessage(newMessageContent)">

    First Name: <input type="text" ng-model="firstName"><br>
    Last Name: <input type="text" ng-model="lastName"><br>
    <br>
    Full Name: {{firstName + " " + lastName}}
    <textarea id="typeMessageBox" placeholder="Write here and hit enter to send..." type="text submit" class="form-control-lg form-control" ng-model="newMessageContent"></textarea>
    </form>
</div> 

Solution

You can use ng-keypress and then check if keypress is equal enter then call to submit form function

On your textarea should be

<textarea ng-keypress="getkeys($event)" ng-model="newMessageContent"></textarea>

Then your angular code shold be

$scope.getkeys = function (event) {        
   if(event.keyCode == 13){
     $scope.sendMessage( $scope.newMessageContent );
   }        
}
