Angularjs 如何向模型添加属性？

我有一个模型X，它代表一个任务。 我想向模型添加一些属性。单击do按钮时，我想向单击的特定x模型添加一个“doRequested”属性。单击“资金”按钮时，我想向该特定任务添加特定属性。另外，我想在创建任务时为当前用户添加一个admin属性集。这些属性必须始终与特定任务关联，以便任务“task.attributeName”将给出该属性的确切值

这种事情是不是应该用AngularJs来做？如何修改$scope.todoList，使todoList中的每个项目都具有以下与之关联的todoText、todoAdmin:、doRequested和fundRequested属性：

$scope.todoList.push({todoText:$scope.todoInput, done:false});

由于我来自Rails的背景，这似乎太复杂了，我不知道该怎么做

以下是我的看法：

<div ng-app="facebookExample" view-title="Tasks">
<div ng-controller="todoController">
<h1>Tasks</h1>

 <div class="item item-input-inset">
 <label class="item-input-wrapper">
 <!-- The actual input tag which is bound to the todoInput using ng-model -->
 <input type="text" placeholder="Add New Item" ng-model="todoInput" size="100"> 
 </label>
 <!-- Our button thay will call our funtion to add a new todo item -->
<button class="button button-small" ng-click="todoAdd()">
Add Task
</button>
</div>

  <div ng-repeat="x in todoList">
  <li class="item item-checkbox">
  &nbsp;&nbsp;&nbsp;<label class="checkbox">
  </label>
  <!-- this is the checkbox element, you will see it is bound to the done setting in the items array -->
  <!-- When clicked it calls the update function to update the item to its done status -->
  <input type="checkbox" ng-model="x.done" ng-click="update()"/>
  <!-- this is a span tag that shows the item text, I am using ng-bind, instead of the span tag we could have used {{x.todoText}} as well -->
  <button class="fund-button" style= "float: left;" ng-click="fund(x)">Fund</button>
  <span>{{x.todoText}}</span>
  <button class="doButton" style= "float: right; margin-right: 2px;" ng-click="do(x)">Do</button>
  </li>
  </div>
  <!-- the remove button will call the remove function and remoave all items that   are marked done -->
  <button class="button button-block button-assertive" ng-click="remove()">Remove Checked Tasks
  </button>
  </div>
   </div>

不要想得太多，这仍然是JavaScript，您可以向对象添加属性。如果你想得到帮助，你应该把你的代码简化成一个简单的例子，说明你想做什么——删除我们不需要的东西，我不明白这是你的问题。为什么不将想要的属性添加到这些函数的作用域中呢。例如，在fund中，您可以根据需要向特定任务添加特定属性。@floribon是对的，不要使代码过于复杂。您可以轻松地添加属性并扩展您的模型。如果您的模型是一个对象，只需像x.doRequest=true那样操作即可。任何新成员都会自动加入x谢谢你们我现在就知道了

 facebookExample.controller('todoController', ['$scope', function($scope) {
 // Initialize the todo list array
 //if local storage is null save the todolist to local storage
$scope.todoList = [];

if (localStorage.getItem("mytodos") === null)
{

 localStorage.setItem("mytodos", angular.toJson($scope.todoList));

 }else
 {
 //set the todolist from local storage
 $scope.todoList = angular.fromJson(localStorage.getItem("mytodos"));
 }


 // Add an item function
 $scope.todoAdd = function() {
 //check to see if text has been entered, if not exit
 if ($scope.todoInput === null || $scope.todoInput === ''){return;}

 //if there is text add it to the array
 $scope.todoList.push({todoText:$scope.todoInput, done:false});

 //clear the textbox
 $scope.todoInput = "";

 //resave the list to localstorage
 localStorage.setItem("mytodos", angular.toJson($scope.todoList));
 };





















  //Do button
  $scope.do = function(){

  };



 $scope.doForFree = function(x){


 };











 //fund button

 $scope.fund = function(x){

 };
  $scope.remove = function() {
  //copy list
  var oldList = $scope.todoList;
  //clear list
  $scope.todoList = [];
  //cycle through list
  angular.forEach(oldList, function(x) {
  //add any non-done items to todo list
    if (!x.done) $scope.todoList.push(x);
 });
 //update local storage
 localStorage.setItem("mytodos", angular.toJson($scope.todoList));

};

//The Update function
//This waits 100ms to store the data in local storage
$scope.update = function() {
//update local storage 100 ms after the checkbox is clicked to allow it to     process
setTimeout(function(){
 localStorage.setItem("mytodos", angular.toJson($scope.todoList));
 },100);


};

}]);
