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？
欢迎选择我的课程，让我们一起见证您的进步~~
$scope.bb.a = "sdfd";
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.
