javascript - ng-model 绑定(bind)不适用于 ng-template

Question

我正在尝试为 ng-template 进行两种数据绑定(bind)并将其显示为 Angular Material 对话框，但不幸的是我无法绑定(bind)数据。以下是我获取数据的方式:

 $scope.editFormProperties = function (element, ev) {
                formEditViewService.getFormProperties($scope.formId).then(function (data) {
                    $scope.form_properties.Form_Title = data[0].Form_Title;
                    $scope.form_properties.Instructions = data[0].Instructions;
                    $scope.form_properties.Get_Contact_Info = data[0].Get_Contact_Info;
                    $scope.form_properties.Get_Address_Info = data[0].Get_Address_Info;
                    $scope.form_properties.End_Date = data[0].End_Date;
                    $scope.form_properties.Complete_Message = data[0].Complete_Message;
                });
                $mdDialog.show({
                    controller: DialogController,
                    templateUrl: 'dialog2.tmpl.html',
                    parent: angular.element(document.body),
                    targetEvent: ev,
                    clickOutsideToClose: true,
                    fullscreen: false
                })
                .then(function (answer) {
                    if (answer === "proceed") {
                        element.IsDeleted = true;
                        return $scope.elements;
                    } else {
                        $mdDialog.cancel();
                    }
                }, function () {
                    $mdDialog.cancel();
                });

            };

这就是模板标记:

<script type="text/ng-template" id="dialog2.tmpl.html">
    <hide-gt-sm ng-cloak>
        <form>
            <md-toolbar class="md-toolbar-tools md-warn">
                <p>EDIT: Form Properties</p>
                <span flex></span>
                <md-button class="md-icon-button" ng-click="cancel()">
                    <i class="material-icons">close</i>
                </md-button>
            </md-toolbar>
            <md-dialog-content layout="column" layout-align="center center" ng-cloak flex="percentage" layout-margin layout-fill>
                <div class="md-dialog-content" style="width: 500px; overflow-y: hidden;">

                <md-button ng-click="answer('save')" class="save-button">
                    save properties

                <md-button ng-click="answer('cancel')" class="cancel-button">
                    cancel changes
                </md-button>
            </md-dialog-actions>
        </form>
</script>

我可以看到 $scope 获取了正确的数据，但它没有出现。有什么想法吗？

我找到了解决方案，这很简单 - 我没有通过范围。对话框设置应如下所示:

     $mdDialog.show({
                    controller: DialogController,
                    scope: $scope,
                    templateUrl: 'dialog2.tmpl.html',
                    parent: angular.element(document.body),
                    targetEvent: ev,
                    clickOutsideToClose: true,
                    fullscreen: false
                })
