我在模式上有一个按钮（链接），当点击时（copySummaryToTask（$ event））应该将页面的$ scope元素（thisRequest）中的数据复制到模态的$ scope中元素（nTask）。它将正确的数据复制到$ scope中，但即使我使用$ scope，数据也不会出现在模态中。$ apply（）;
这里是plunkr。
这是我的控制人员：
var myApp = angular.module('myApp', []);
myApp.controller('MainController', function($scope){
$scope.NewTaskPane = false;
$scope.thisRequest = {
ID: 543,
Title: 'Create This Wonderful SharePoint 2013 SPA',
Request_Summary: "Rule fruit and under female she'd every signs creepeth good Night, fly lesser they're be green cattle and living tree also spirit us years two. Seasons he good under creepeth fifth air is. For morning. It creeping multiply from, saying.",
Request_Type: 'Web'
};
$scope.Tasks = [
{ID: 20, Title: 'Prototype App', Assigned_To: 'Wayne, Bruce', Status: 'Completed', TOT: 4.5},
{ID: 21, Title: 'Develop App CSS', Assigned_To: 'Prince, Diana', Status: 'Completed', TOT: 6}
];
$scope.addNewTask = function($event){
$event.preventDefault();
$scope.NewTaskPane = true;
$scope.nTask = {
ID: $scope.Tasks.length + 1,
Request_ID: $scope.thisRequest.ID,
Title: $scope.thisRequest.Title,
Status: 'Assigned',
Resource_Instructions: ''
};
};
$scope.copySummaryToTask = function($event){
$event.preventDefault();
//alert($scope.thisRequest.Request_Summary);
$scope.nTask.Resource_Instructions = $scope.thisRequest.Request_Summary;
if (!$scope.$$phase) { $scope.$apply(); }
} // end copySummaryToTask fn
}); // end main controller

答案 0 :(得分：1)
您的观点中有一个拼写错误：
<textarea class="form-control" rows="5">{{ntask.Resource_Instructions}}</textarea>
...其中ntask应为nTask。修复后，您将不需要$scope.apply()：
$scope.copySummaryToTask = function($event){
$event.preventDefault();
$scope.nTask.Resource_Instructions = $scope.thisRequest.Request_Summary;
} // end copySummaryToTask fn
答案 1 :(得分：0)
替换
<textarea class="form-control" rows="5">{{ntask.Resource_Instructions}}</textarea>
使用
<textarea class="form-control" rows="5" ng-model="nTask.Resource_Instructions"></textarea>
这样做，并捕获用户添加的任何新文本。
