JavaScript / AngularJS：将数组值转换为Integer

Question

Can't seem to find an answer for this. I have a select box which when clicked on maps to my model -

<select class="form-control"
        size="8"
        ng-model="Info.FolderId"
        ng-options="Folder.Id as Folder.Name for Folder in AvailableFolders">
</select> 

So the model holds the Id of the folder. However that Id will not be stored as "1" or "2" it will be stored as [1] or [2].

Is there an easy way of converting this using something like ng-change, or an easier way I should be going about doing this?

Try this.

<select class="form-control"
        size="8"
        ng-model="Info.FolderId"
        ng-options="Folder.Id[0] as Folder.Name for Folder in AvailableFolders">
</select>
