我有一个使用ng-submit的表单.不幸的是,即使表单无效,按Enter或单击提交仍然有效.调用ng-submit方法.

CodePen示例：http://codepen.io/calendee/pen/tgFhq

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

  <label for="firstname">First Name:</label>
  <input type="text" name="firstname" ng-model="data.firstname" required="true" ng-minlength="4" ng-maxlength="10">

    <div class="errors">
      <p>firstname Errors:</p>
      <p ng-show="testForm.firstname.$error.required">firstname is required</p>
      <p ng-show="testForm.firstname.$error.minlength">firstname is too short</p>
      <p ng-show="testForm.firstname.$error.maxlength">firstname is too long</p>
    </div>              

    <label for="lastname">Last Name:</label>
      <input type="text" name="lastname" ng-model="data.lastname" ng-required="true" ng-minlength="4" ng-maxlength="10">

    <div class="errors">
      <p>lastname Errors:</p>
      <p ng-show="testForm.lastname.$error.required">lastname is required</p>
      <p ng-show="testForm.lastname.$error.minlength">lastname is too short</p>
      <p ng-show="testForm.lastname.$error.maxlength">lastname is too long</p>
    </div>              


  <button class="button button-balanced" type="submit">Submit</button>

</form>

如果我更改表单的ng-form,即使表单有效,提交事件也根本不起作用.

CodePen样本：http://codepen.io/calendee/pen/imJdc

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

  <label for="firstname">First Name:</label>
  <input type="text" name="firstname" ng-model="data.firstname" required="true" ng-minlength="4" ng-maxlength="10">

    <div class="errors">
      <p>firstname Errors:</p>
      <p ng-show="testForm.firstname.$error.required">firstname is required</p>
      <p ng-show="testForm.firstname.$error.minlength">firstname is too short</p>
      <p ng-show="testForm.firstname.$error.maxlength">firstname is too long</p>
    </div>              

    <label for="lastname">Last Name:</label>
      <input type="text" name="lastname" ng-model="data.lastname" ng-required="true" ng-minlength="4" ng-maxlength="10">

    <div class="errors">
      <p>lastname Errors:</p>
      <p ng-show="testForm.lastname.$error.required">lastname is required</p>
      <p ng-show="testForm.lastname.$error.minlength">lastname is too short</p>
      <p ng-show="testForm.lastname.$error.maxlength">lastname is too long</p>
    </div>              


  <button class="button button-balanced" type="submit">Submit</button>

</ng-form>

有没有人对我在这里做错了什么有建议？
