angular.js - angularjs如何给对象加一个属性呢，在js中？

Question

例如，我在jsp或者html文件中如此写一个作用域：
<input type="text" ng-model="bb.hello"/>

然后在js中，我如果想给bb添加一个属性该如何写呢？

在js中，如果直接写

bb.a="sdfd";
就回报错的。
那么该如何写符合这种东西呢？

Answer 1

 
$scope.bb.a = "sdfd";

Answer 2

As far as writing is concerned, if a variable in HTML, such as bb, reaches the controller, it needs to be preceded by $scope., which is $scope.bb.
