dynamic attribute reference inside angular ng-repeat

Question

I build a dropdown directive, and it work with a different objects types, each object has own particular atributes, i need to get some particular field inside a ng-repat of my dropdown, now, it's fixed cityName, how i can change cityName for a variable, which stay on controller?

  <div class="listCombo" ng-show="showDrop" ng-mouseleave="lostFocus()">
        <table>
            <tr ng-repeat="result in results" ng-click="selectItem(result)">
                <td> {{result.cityName}} </td>
            </tr>
        </table>
    </div>

For example, i need to get peopleName rather than cityName.

I don't really understand what do you want, you want to set cityName ore opepleName on td? — Minkyu Kim

Yes it is possible to change the property attribute dynamically in ng-repeat.Below is a sample example code on how to achieve this.

1) You should have data source like below to make things easy

$scope.objectsList = [{
                'name': 'Vikram',
                'Age': '25',
                'sex': 'M'
            }, {
                'name': 'Quantum',
                'Age': '26',
                'sex': 'F'
            }, {
                'name': 'Katty',
                'Age': '22',
                'sex': 'F'
            }];
            $scope.objName = 'name';

2) In your HTML have something like this in your ng-repeat

<p ng-repeat="obj in objectsList">
    {{obj[objName]}} <!-- here by changing the 'objName' we can decide which property value to be displayed dynamically-->

</p>
<input type="text" ng-model="objName"/><!-- This is for example..u dont need this-->

If you look at JS we have mentioned $scope.objName = 'name'; i.e it will display all the names in a list,if we change the $scope.objName to 'Age' then it will display corresponding ages in the data source.

Hope this is answers your question.

If you want to show cityName or peopleName conditionally in td,

you can use like this.

It's not building DOM conditionally but you can see like that. Wheather it is not a good way on you, but I hope it to help you.

 <div class="listCombo" ng-show="showDrop" ng-mouseleave="lostFocus()">
        <table>
            <tr ng-repeat="result in results" ng-click="selectItem(result)">
                <td ng-show="someCondition(result) === true"> {{result.cityName}} </td>
                <td ng-show="someCondition(result) === false"> {{result.cityName}} </td>
            </tr>
        </table>
    </div>
