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() {
$mdDialog.cancel();
};
}
}]);
HTML
<div class="input-container float-icon" flex="100" layout="row" ng-repeat="task in tasklist">
<md-input-container flex="100">
<label>New Task...</label>
<input type="text" ng-model="taskTitle" name="taskTitle">
<md-button aria-label="Expandir Tarefa" class="md-icon-button expand-icon" ng-click="expandTask()">
<md-tooltip hide-sm>Expand Task</md-tooltip>
<i class="fa fa-expand"></i>
</md-button>
</md-input-container>
{{taskTitle}}
</div>
最佳答案
您应该将 task
对象从 ng-repeat 传递到 ng-click。
例如 ng-click="expandTask($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>
