从控制器访问角度引导模态形式

Question

我试图从模态控制器(Plunkr)访问表单,但myForm似乎不可访问.如何获得工作警报:

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal, $log) {
  $scope.open = function () {
    var modalInstance = $modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl          
    });       
  };
};

var ModalInstanceCtrl = function ($scope, $modalInstance) {
  $scope.submit = function() {
    // How to get this?
   alert($scope.myForm.$dirty);
  };

  $scope.ok = function () {
    $modalInstance.close();
  };

  $scope.cancel = function () {
    $modalInstance.dismiss('cancel');
  };
};

和模板:

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
          <form name="myForm" novalidate>
          <input type="email" value="hello">
          </form>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="submit()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn" ng-click="open()">Open me!</button>
    <div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>

Answer 1

Angular-UI模式使用transclusion来附加模态内容,这意味着在modal中创建的任何新作用域条目都是在子作用域中创建的.这与form指令一起发生.

您可以尝试使用(Angular 1.2.16)将表单附加到父作用域:

<form name="$parent.userForm">

它userForm是在模态控制器中创建和使用的$scope.由于范围继承userForm访问在标记中保持不变.

<div ng-class="{'has-error': userForm.email.$invalid}"}>

Answer 2

这是 ui-bootstrap中的一个已知错误.所以注入$ modalInstance现在工作正常.

解决方法是将表单实例显式传递给提交函数:

<form name="myForm" novalidate ng-submit="submit(myForm)">
  <div class="modal-header">
    <h3>I'm a modal!</h3>
  </div>
  <div class="modal-body">
    <input type="email" value="hello">
  </div>
  <div class="modal-footer">
    <button class="btn btn-primary" type="submit">OK</button>
    <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
  </div>
</form>

var ModalInstanceCtrl = function ($scope, $modalInstance) {
  $scope.submit = function(myForm) {
   alert(myForm.$dirty);
  };
};
