Check if the data exist in a dropdown?

So I created a dropdown like the following:

<select style="width: 100%" ng-model="selectPosition" ng-Change="GetPosition(selectPosition)">
        <option value="Partner">Partner</option>
        <option value="Associate">Associate</option>
        <option value="Council">Council</option>
</select>

In my controller, I make the option from the dropdown selected depending on the data. Now I want to check if the data exist in that dropdown. How do I do that?

$scope.selectPosition = $scope.Data.CompanyTitle;

If you want to do this using angularjs than you have to use ng-options to check whether or not there is data in "select".

or your can do like this also in your controller.

document.getElementsByTagName('select')[0].children.length

or document.getElementById('select')[0].children.length

hope this helps you

Make your options using ng-options 

<select ng-options="item as item.label for item in selectOptions track by item.id" ng-model="selectPosition"></select>

Then you will be able to loop through selectOptions and check.
