是否有一个角度指令可以限制DOM中元素的范围

Question

Hi I was just wondering if there is some built-in angular directive (ng-some-directive) that allows you to restrict the scope to a particular model for the desired DOM element.

I belive I have seen something similar done before, but maybe I am thinking of knockout.js

<script>
    angular.module('example', [])
    .controller('ExampleController', ['$scope', function($scope) {
        $scope.heading = 'Some Value';
        $scope.complexModel = {...}
     }]);
</script>
<div ng-controller="ExampleController">
    <h1>{{ heading }}</h1>
    <div ng-some-directive='complexModel.to.long.really.annoying'>
        <input type='text' ng-model='variable' /> // Actually coming from complexModel.to.long.really.annoying.variable
    </div>
</div>

This is a drastically simplified version

Though its not meant for it

<div ng-init='sn = complexModel.to.long.really.annoying'>
        <input type='text' ng-model='sn' />
</div>
