          <button class="btn btn-default" data-dismiss="modal">Cancel</button>
          <button class="btn btn-primary" ng-disabled="addform.$invalid" ng-click="addNav()">Add</button>

来自https://docs.angularjs.org/guide/forms#binding-to-form-and-control-state：

表单是一个实例 FormController。可以选择使用表单实例将表单实例发布到范围内 name属性。

您必须使用name属性在$scope中提供表单实例，但您使用id属性：

<form name="addform" class="form-horizontal">
  <!-- ... -->
</form>

按钮不是禁用使用ng-disabled
