How do I apply ng-translate to translate options inside a select box.
For example:
Template:
<select class="form-control" ng-model="me.gender" ng-options="gender.name for gender in genders">
</select>
Controller:
$scope.genders = [{code: "M", name:"TXT_MALE"}, {code: "F", name:"TXT_FEMALE"}]
enUS.json:
{
"TXT_MALE": "Male",
"TXT_FEMALE": "Female",
}
I tried adding filter like ng-options="gender.name for gender in genders | translate" but obviously it was adding filter to $scope.genders array instead of single element
I tried writing own filter (I am new to this)
filter('translateArrayObj', ['$translate', '_', function($translate, _) {
return function(arr) {
var arr2 = [];
angular.forEach(arr, function (value, key) {
$translate(value.name).then(function(translation) {
var obj2 = angular.copy(value);
obj2.name = translation;
obj2.code = value.code;
arr2.push(obj2);
});
});
return arr2;
}
}])
But I got following error
Error: [$rootScope:infdig] 10 $digest() iterations reached. Aborting!
It seems like a simple task but it has already taken half of my day, what am I doing wrong :(
You need to apply the filter to gender.name and not to the genders array:
<select ng-model="me.gender" ng-options="gender.name | translate for gender in genders"></select>
