AngularJS在变量问题中存储表单数据

Question

我使用NG提交按钮尝试将提交数据的点击事件绑定到角度变量并遇到问题。

角度代码：

formApp.controller('formController', function ($scope) {

// we will store all of our form data in this object
// function to process the form
$scope.processForm = function () {
    var fn = $scope.firstname;
    alert('your reccommendation has been submitted!' + fn);


};

NG-submit位于html中

<form id="signup-form" ng-submit="processForm()">
                <!-- our nested state views will be injected here -->
                <div id="form-views" ui-view></div>
            </form>

填写名字数据的地方是：

 <strong>First Name:</strong>
<input name="FirstName" size='16' ng-model="firstname"  />
<br />
<br />

现在，在您说NG-submit不在我的表单附近之前，表单视图与初始表单相关联。当您按提交时警报工作正常，但变量返回未定义。任何帮助都会有所帮助！
