Angularjs 如何为ng模型定义赋值

我正在应用程序中使用typeahead的ui引导

<input type="text" ng-model="newItem.id" class="form-control">
<pre>Model: {{customSelected | json}}</pre>
<input type="text" ng-model="customSelected" typeahead="asset as asset.asset_name for asset in assets | filter:{asset_name:$viewValue}" class="form-control">

---

如果要将选定的

资产
id
分配给
新项目.id
：

    function ctrl($scope){
        $scope.assets = [{"id":"1","asset_reg_no":"AST1","asset_name":"Omega Shopping Complex","asset_type_id":"2","description":"Shopping Complex in Calicut","created_on":"2014-01-28 16:03:23","asset_type_name":"Building"},{"id":"2","asset_reg_no":"AST2","asset_name":"Keedam Chicken Farm","asset_type_id":"2","description":"Chicken farm in Valivida","created_on":"2014-01-28 16:04:06","asset_type_name":"Building"}];

    $scope.newItem = {};
    $scope.$watch('customSelected', function(asset, oldAsset){
    $scope.newItem.id = asset.id;
    $scope.newItem.text = asset.asset_name;
      });

    }

如果我理解你，这就是你想要的

这里的问题是，当我选择项目时，文本框显示的是id而不是文本，我希望自动完成的文本会出现在那里。当我选择以前的代码时，我将得到如下结果：
{“id”：“1”，“asset\u reg\u no”：“AST1”，“asset\u name”：“Omega购物中心”，“asset\u type\u id”：“2”，“description”：“Calicut购物中心”、“创建日期”：“2014-01-28 16:03:23”、“资产类型名称”：“Building”}
我想将
id
分配给一个隐藏的文本框，并将
资产注册号
分配给另一个文本。
<input type="text" ng-model="newItem.id" typeahead="asset.id as asset.asset_name for asset in assets | filter:{asset_name:$viewValue}" class="form-control">

    function ctrl($scope){
        $scope.assets = [{"id":"1","asset_reg_no":"AST1","asset_name":"Omega Shopping Complex","asset_type_id":"2","description":"Shopping Complex in Calicut","created_on":"2014-01-28 16:03:23","asset_type_name":"Building"},{"id":"2","asset_reg_no":"AST2","asset_name":"Keedam Chicken Farm","asset_type_id":"2","description":"Chicken farm in Valivida","created_on":"2014-01-28 16:04:06","asset_type_name":"Building"}];

    $scope.newItem = {};
    $scope.$watch('customSelected', function(asset, oldAsset){
    $scope.newItem.id = asset.id;
    $scope.newItem.text = asset.asset_name;
      });

    }
