<div class="col-xs-12" ng-controller="test">
        <p>test控制器</p>
        <p>ary: {{ary}}</p>
        <p>str: {{str}}</p>
        <div ng-controller="child">
          <P>child控制器</P>
          <input ng-model="ary" ng-list="">
          <p>子ary：{{ary}}</p>
          <input ng-model="str">
          <p>子str：{{str}}</p>
        </div>
      </div>

    app.controller("test",["$scope",function ($scope) {
      $scope.ary = ["qwe","adad"];
      $scope.str= "asda";
    }]);
    app.controller("child",["$scope",function ($scope) {

    }])

只是继承，不改变父作用域的值

<div class="col-xs-12" ng-controller="test">
        <h1><%= title %></h1>
        <p>test控制器</p>
        <p>ary: {{ary}}</p>
        <p>ary01: {{ary01}}</p>
        <p>str: {{str}}</p>
        <div ng-controller="child">
          <P>child控制器</P>
          <input ng-model="$parent.ary" ng-list="">
          <p>子ary：{{ary}}</p>
          <input ng-model="ary01.as" ng-list="">
          <p>子ary：{{ary01}}</p>
          <input ng-model="$parent.str">
          <p>子str：{{str}}</p>
        </div>
      </div>

    app.controller("test",["$scope",function ($scope) {
      $scope.$watch("test",function (newvalue) {
        console.log(newvalue);
      })
      $scope.ary = ["qwe","adad"];
      $scope.ary01 = {as:["qwe","adad"]};
      $scope.str= "asda";
    }]);
    app.controller("child",["$scope",function ($scope) {

    }])

继承并修改

总结：当你检索字面值时，原型链并不起作用。如果test也同时被更新的话，检索原型链是必须的；但如果值是一个对象，这就会发生。（记住，在Javascript中，函数、数组和对象都是对象）
