仅绑定一次属性(如 bindonce)

Bind attribute only once (like bindonce)

component is it possible to bind in the style like bindonce?请举个例子。

因为 angular 有 v1.3,它使用以下语法来绑定

<div ng-repeat="item in ctrl.results">
    <div>{{ ::item.name }} - {{ ::item.description }}</div>
</div>
<div ng-if="::vm.user.loggedIn"></div>
for class
ng-class="::{ loggedIn: vm.user.loggedIn }"
