从控制器访问角度引导模态形式

I am trying to access the form from the modal controller (Plunkr) but myForm doesn't seem to be accessible. How to get alert call to work:

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');
  };
};

And template:

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>

This was an known bug in ui-bootstrap. So injecting $modalInstance works fine now.

这是ui-bootstrap中的已知错误。所以注入$ modalInstance现在工作正常。

Workaround is to pass form instance to the submit function explicitly:

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);
  };
};

Angular-UI modals are using transclusion to attach modal content, which means any new scope entries made within modal are created in child scope. This happens with form directive.

Angular-UI模式使用transclusion来附加模态内容，这意味着在modal中创建的任何新范围条目都是在子范围内创建的。这与form指令一起发生。

You can try to attach form to parent scope with (Angular 1.2.16):

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">

The userForm is created and available in modal's controller $scope. Thanks to scope inheritance userForm access stays untouched in the markup.

userForm已在模态的控制器$ scope中创建并可用。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}"}>

In your controller add at the top:

在您的控制器中添加顶部：

$scope.form = {};

In the html template:

在html模板中：

<form name="form.yourFormName">

Validation on html elements:

验证html元素：

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

In the end I went with the answer given by gertas, but the following is another way of resolving this.

最后我得到了gertas给出的答案，但以下是解决这个问题的另一种方法。

//place a method on modal controller scope

        $scope.setFormReference = function (myForm) {
            $scope.myForm = myForm
        };

//call this using an angular expression in your modal template

       {{ setFormReference(loginForm)}}
