将输入值传递给$mdDialog

Pass input value to $mdDialog

本文关键字:mdDialog 输入 值传      更新时间:2023-09-26

我正在尝试将表单输入传递到对话框(例如标题(。问题是:它没有得到形式$scope

如果我在控制器中设置$scope,它将显示正常(例如,请参见$scope.text(。但是,如果我尝试获取表单$scope(请参阅`$scope.taskTitle(,它就不会显示任何内容。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。

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

在$mdDialog控制器中,您将可以访问该对象:

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
        });
    };
}]);

在模式模板中,您将使用controllerAs表示法访问任务对象,例如:

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

保持最小值

并创建一个具有范围变量的控制器

$scope.expandTask = (e, task) =>
    $mdDialog.show({
        templateUrl: 'dialog.template.html',
        controller: $scope => $scope.taskName = task.name
    })

taskName现在是$scope变量,可以在对话框模板

中使用
