回答1:

Modify your ng-submit, you don't have to put main.submitForm()

<form name="userForm" ng-submit="submitForm()" novalidate>

Also, you have an error in your controller with your cordova injection.

Have a look at this Plunker

回答2:

I don't see any where in your index.html having ng-view, from where your view gets loaded. place <div ng-view></div>

回答3:

Since you call submitForm on the controller variable you should not set the function on $scope but on the controller:

// $scope.submitForm = function() {
this.submitForm = function() {
