Angular 通过使用模型进行编辑,使此任务比 Backbone 更简单,然后您更新原始列表并清除编辑模型。
风景:
<div ng-app='App'>
<div ng-controller='mainCtrl'>
<div ng-controller='childCtrl'>
<strong>Controller</strong>
<ul>
<li ng-repeat='item in list'>{{item.name}} <button ng-click='edit($index)'>+</button></li>
</ul>
<div ng-show='editModel.name'>
Name: <input type="text" ng-model='editModel.name'/> <button ng-click='save()'>Save</button><button ng-click='cancelEdit()'>Cancel</button>
</div>
</div>
</div>
角度应用程序:
angular.module('App', [])
.controller('mainCtrl', ['$scope', function($scope){
$scope.list = [ {name:'item 1'}, {name:'item 2'}, {name:'item 3'} ];
}])
.controller('childCtrl', ['$scope', function($scope){
$scope.editModel = {};
$scope.edit = function(index){
$scope.editModel.index = index;
$scope.editModel.name = $scope.list[index].name;
};
$scope.cancelEdit = function(){
$scope.editModel = {};
};
$scope.save = function(){
if($scope.editModel.hasOwnProperty('index')){
$scope.list[$scope.editModel.index] = $scope.editModel;
}
else if($scope.editModel.name && $scope.editModel.name.length){
$scope.list.push($scope.editModel);
}
$scope.cancelEdit();
};
}]);

我正在使用控制器嵌套,因此该列表可以被您在应用程序中拥有的其他控制器使用,或者您可以创建一个控制器来处理编辑。
