Reset form on submit - angularjs

Question

I am submitting a form and then making all the field empty but it's not working. Form is getting submitted successfully but the fields are not getting reset. I am using angular-material for styling. Updated controller.
Html
<form name="myform">
<md-input-container>
<label for="name">Contact Name</label>
<input type="text" md-maxlength="20" required="" md-no-asterisk name="name" ng-model="info.name" md-autofoucs>
<div ng-messages="myform.name.$error" role="alert">
<div ng-message="required">This is required.</div>
<div ng-message="md-maxlength">The name has to be less than 20 characters long.</div>
</div>
</md-input-container>
<md-input-container>
<label for="phone">Phone Number</label>
<input type="text" name="phone" required md-no-asterisk ng-model="info.phone">
<div ng-messages="myform.phone.$error">
<div ng-message="required">This is required.</div>
</div>
</md-input-container>
<md-input-container>
<label for="email">Email</label>
<input type="text" name="email" ng-model="info.email">
</md-input-container>
<md-input-container>
<md-button class="md-primary" ng-click="saveit(info)">Save</md-button>
<md-button class="md-primary">Cancel</md-button>
</md-input-container>
</form>
**Function in Controller**
angular.module('contact', ['ui.router', 'ngMaterial', 'templates','ngMessages'])
.config(['$mdThemingProvider', '$stateProvider', function ($mdThemingProvider, $stateProvider) {
$mdThemingProvider.theme('default')
.primaryPalette('blue')
.accentPalette('orange');
$stateProvider
.state('home', {
url: '',
templateUrl: 'templates/home.html',
controller: 'MainCtrl as vm'
});
}]).controller('MainCtrl', function ($scope, $mdSidenav,$mdDialog,$mdToast, contacts) {
var vm = this;
$scope.searchText ="";
$scope.toggleSidenav = function(){
$mdSidenav('left').open();
};
contacts.getall().then(function(response){
console.log(response.data);
$scope.people = response.data;
});
$scope.saveit = function(detail, myform){
if (!detail.name || !detail.phone) { return ;}
contacts.add({
name: detail.name,
phone: detail.phone,
email: detail.email
});
$mdToast.show(
$mdToast.simple()
.content("ContactAdded!")
.position('top, right')
.hideDelay(2000)
);
$scope.people.push(detail);
$scope.info = {};
$scope.myform.$setPristine();
$scope.myform.$setUntouched();
};
$scope.showConfirm = function(ev, person) {
var confirm = $mdDialog.confirm()
.title('Are you sure?')
.ariaLabel('Lucky day')
.targetEvent(ev)
.ok('Please delete it!')
.cancel('I want to keep it.');
$mdDialog.show(confirm).then(function() {
contacts.deletethis(person.id).then(function(){
$mdToast.show(
$mdToast.simple()
.content("Deleted!")
.position('top, right')
.hideDelay(2000)
);
});
var index = $scope.people.indexOf(person);
$scope.people.splice(index,1);
}, function() {
$scope.status = 'You decided to keep your debt.';
});
}; });

<form name="myform">
<input type="text" ng-model="info.name">
<input type="text" ng-model="info.phone">
<input type="text" ng-model="info.email">
</form>
app.controller('MainCtrl', function($scope) {
$scope.info = {}; // name, phone, email
$scope.saveit = function() {
$scope.info.name = ''; // reset name
$scope.info.phone= ''; // reset phone
$scope.info.email= ''; // reset email
// reset form and disable error messages
$scope.myform.$setPristine();
$scope.myform.$setUntouched();
};
});

Answer 2

You are not using $scope and this for controller correctly. You can use $scope or controller as syntax to bind your scope with view.
I suggest you to read more about it here.
Update your saveit() function inside controller as below:
app.controller('MainCtrl', function($scope, $mdSidenav, $mdDialog, $mdToast) {
var vm = this;
vm.info = {};
//your rest the code
vm.saveit = function() {
//do your operations here
vm.info = {};
};
});
Update your html page as below:
<div ng-controller="MainCtrl as vm">
<form name="myform">
<md-input-container>
<label for="name">Contact Name</label>
<input type="text" ng-maxlength="20" required md-no-asterisk name="name" ng-model="vm.info.name" md-autofoucs>
</md-input-container>
<md-input-container>
<label for="phone">Phone Number</label>
<input type="text" name="phone" required md-no-asterisk ng-model="vm.info.phone">
</md-input-container>
<md-input-container>
<label for="email">Email</label>
<input type="text" name="email" ng-model="vm.info.email">
</md-input-container>
<md-input-container>
<md-button class="md-primary" ng-click="vm.saveit()">Save</md-button>
<md-button class="md-primary">Cancel</md-button>
</md-input-container>
</form>
</div>

Answer 3

Give $setPristine to reset the form after saving.
$scope.myform.$setPristine();

Answer 4

Another approach
app.controller('MainCtrl', function($scope, $mdSidenav, $mdDialog, $mdToast) {
var vm = this;
vm.info = {};
vm.saveit = function($event)
{
var form = angular.element($event.target).parent("form")[0];
if (form !== undefined) form.reset();
};
});
<div ng-controller="MainCtrl as vm">
<form name="myform">
<md-input-container>
<label for="name">Contact Name</label>
<input type="text" ng-maxlength="20" required md-no-asterisk name="name" ng-model="vm.info.name" md-autofoucs>
</md-input-container>
<md-input-container>
<label for="phone">Phone Number</label>
<input type="text" name="phone" required md-no-asterisk ng-model="vm.info.phone">
</md-input-container>
<md-input-container>
<label for="email">Email</label>
<input type="text" name="email" ng-model="vm.info.email">
</md-input-container>
<md-input-container>
<md-button class="md-primary" ng-click="vm.saveit($event)">Save</md-button>
<md-button class="md-primary">Cancel</md-button>
</md-input-container>
</form>
</div>
