angularJS bind to input's enter key and submit if input is button
Question
I have such directive, to go to next input (or button) in modal window:
.directive('autoVrm', function () {
return function (scope, element, attrs) {
var counter = 0;
element.bind("keydown keypress", function (event) {
console.log(element);
if(event.which === 13) {
counter++;
event.preventDefault();
var elementToFocus = element.find('input')[counter] || element.find('button')[1];
console.log(elementToFocus.type);
if(angular.isDefined(elementToFocus))
elementToFocus.focus();
if (elementToFocus.type === 'button'){
counter = -1;
elementToFocus.bind("keydown keypress", function (eventSubmit) {
if(eventSubmit.which === 13) {
console.log('submit');
}
});
}
}
});
};
but i have one trouble, if i'm on button, and click enter i get:
Uncaught TypeError: undefined is not a function
but why? how to make enter click to submit form? without dependency to controller?

Try angular.element(elementToFocus).bind for the Uncaught TypeError.
Regarding your new comment:
If this is defined in your controller
$scope.registerUser = function() {
...
}
Then call it in the directive simply by
elementToFocus.bind("keydown keypress", function (eventSubmit) {
if(eventSubmit.which === 13) {
scope.registerUser();
}
});
As a guess, you could do something like check the attrs parameter to get the value of 'data-ng-click' and call the appropriate function:
elementToFocus.bind("keydown keypress", function (eventSubmit) {
if(eventSubmit.which === 13) {
if (attrs.dataNgClick == "registerUser()" {
scope.registerUser();
}
else if (attrs.dataNgClick == "sign()" {
scope.sign();
}
else if (attrs.dataNgClick == "frgtPassword()" {
scope.frgtPassword();
}
}
});

This behavior is already defined in web technologies. When you press ENTER inside a form, it is submitted. To achieve this, you need to handle the right event (ng-submit). You can achieve the effect you're looking for with less code.
angular.module('app', []) .controller('MyCtrl', function () { var self = this; self.message = "press ENTER to submit"; self.count = 0; this.onSubmit = function () { self.count++; self.message = "form submitted " + self.count + " times"; }; });
