I have an app angular that can be translate both in french and english. I'm using angular translate to do that. The problem is: I receive an array of object from an API and in those object, I have a property bookConditionEn
and a property bookConditionFr
and other like ids.
In a select input , I want to display bookCondition
depending by the current language.
In the controller, I can get the current language with the $translate
service
vm.getCurrentLanguage = function() {
return $translate.use();
}
So, I wonder if in the view I could use a condition in the ng-option.
<select
ng-options="bookCondition.BookCondition for bookCondition in bookCtrl.bookConditions"
ng-model="bookCtrl.bookConditions"
name="Condition" class="form-control"
></select>

It worked your way
<select ng-model="bookCtrl.bookCondition" name="Condition" class="form-control">
<option ng-if="bookCtrl.getCurrentLanguage() === 'en'" ng-repeat="bookCondition in bookCtrl.bookConditions" value="{{bookCondition}}">{{bookCondition.BookCondition}}</option>
<option ng-if="bookCtrl.getCurrentLanguage() === 'fr'" ng-repeat="bookCondition in bookCtrl.bookConditions" value="{{bookCondition}}">{{bookCondition.BookConditionFr}}</option>
</select>

You can use conditionals to show/hide options by changing the way you are creating the <select>
:
<select ng-options=ng-model="bookCtrl.bookConditions" name="Condition" class="form-control">
<option
ng-repeat="bookCondition.BookCondition for bookCondition in bookCtrl.bookConditions"
ng-if="vm.getCurrentLanguage==bookCondition.language"
>
</select>
I didn't quite understand how you have your JSON set up so I am assuming you have a property that contains the language (bookCondition.language). You can compare this against the user's currently-selected language which is returned by your vm.getCurrentLanguage
. By the way, I suggest changing that from a function to just be a variable like this:
vm.currentLanguage = $translate.use();
This should be all you need to do to specify options in a conditional manner.
