angularjs - 在 ng-change 上传递所选对象的其他属性

Question

如何从下拉列表/ng-options 中加载的 json 中获取其他属性

在 ng-change 中，我也喜欢传递所选对象的事件类型。

我怎么能做到这一点？

我的观点是这样的

  <div ng-app>
    <div ng-controller="cCtrl">
        <select ng-model="campaign" ng-options="c.id as c.name for c in campaigns" ng-change="search2(c.campaignType)">
            <option value="">-- choose campaign --</option>
        </select>
    </div>
</div>

我的 Controller 看起来像这样

  function cCtrl($scope) {

    $scope.campaigns = [{
        "custID": 1,
        "custName": "aaa ",
        "msgID": 3,
        "msgName": "Email Test Msg",
        "id": 2,
        "name": "Email Test Campaign",
        "description": "Test Campaign",
        "campaignType": "Email",
        "created": "1374229715",
        "isActive": 1,
        "isDeleted": 0
    }];

 $scope.search2 = function (campaignType) {
        alert(campaignType); // not working
        alert($scope.campaign.campaignType); // not working
        //console.log($scope.campaign.campaignType);

    }

}

您可以像这样将选定的对象传递到函数中，而不是传递属性

<select ng-model="campaign" ng-options="c.name for c in campaigns" ng-change="search2(campaign)">
