javascript - 将输入值传递给 $mdDialog

Question

我正在尝试将表单输入传递到我的对话框(例如作为标题)。问题是:它没有得到 $scope 的形式。

如果我设置 $scope sinde Controller ，它将正常显示(例如，参见 $scope.text)。但是，如果我尝试获取表单 $scope(请参阅 `$scope.taskTitle)，它不会显示任何内容。查看我的代码:

JavaScript

app.controller('tasksCtrl', ['$scope', '$mdDialog',  function($scope, $mdDialog){


$scope.teste = 'Just a test, dude';

$scope.expandTask = function() {

    $mdDialog.show({
        clickOutsideToClose: true,
        controller: DialogController,
        scope: $scope,
        preserveScope: true,
        templateUrl: 'models/dialog.tmpl.php',
        locals: {
            id: $scope.tasklist.id,
            title: $scope.taskTitle
        }
    });

}

function DialogController($scope, $mdDialog, id, title) {

    $scope.id = id;
    $scope.title = title;

    $scope.hide = function() {
        $mdDialog.hide();
    };

    $scope.cancel = function() {
        $mdDialog.cancel();
      };
}
}]);

HTML

<div class="input-container float-icon" flex="100" layout="row" ng-repeat="task in tasklist">
    <md-input-container flex="100">
        <label>New Task...</label>
        <input type="text" ng-model="taskTitle" name="taskTitle">
        <md-button aria-label="Expandir Tarefa" class="md-icon-button expand-icon" ng-click="expandTask()">
            <md-tooltip hide-sm>Expand Task</md-tooltip>
            <i class="fa fa-expand"></i>
        </md-button>
    </md-input-container>

    {{taskTitle}}

</div>

您应该将 task 对象从 ng-repeat 传递到 ng-click。

例如 ng-click="expandTask($event, task)"

在您的 $mdDialog Controller 中，您将有权访问该对象:

app.controller('tasksCtrl', ['$scope', '$mdDialog', function ($scope, $mdDialog) {

    $scope.expandTask = function (e, task) {
        //ng-click="expandTask($event, task)"
        $mdDialog.show({
            clickOutsideToClose: true,
            controller: function ($mdDialog) {
                var vm = this;
                vm.task = {};
                vm.task = task;  //your task object from the ng-repeat

                $scope.hide = function () {
                    $mdDialog.hide();
                };
                $scope.cancel = function () {
                    $mdDialog.cancel();
                };
            },
            controllerAs: 'modal',
            templateUrl: 'models/dialog.tmpl.php',
            parent: angular.element(document.body),
            targetEvent: e
        });
    };
}]);

并且在模式模板中，您将使用 controllerAs 符号访问任务对象，例如:

 <h1> {{ modal.task.name }} <h1>
