Wielkie litery filtru z opcjami-ng

Question

Nie znalazłem pierwszej litery wielkimi lub wielkimi literami w ng-options.

My wybierz:

<select ng-model="company.currency.code" ng-options="currency.code as currency.code for currency in currency_list> 
</select> 

W sterowniku:

$scope.currency_list = [ 
    { 
     code: 'eur' 
    }, { 
     code: 'usd' 
    } 
]; 

chciałbym wydrukować "EUR", "USD" lub "EUR", "USD" bez pętli ręcznie mój obiekt.

Czy to możliwe?

Answer 1

To powinno działać:

ng-options="currency.code as (currency.code | uppercase) for currency in currency_list" 

Zobacz docs filtr: https://docs.angularjs.org/api/ng/filter/uppercase

Answer 2

Używaj uppercase filtr.

Spójrz na tym

var app = angular.module('myApp', []); 
 
app.controller('ArrayController', function ($scope) { 
 
    $scope.currency_list = [ 
 
    { 
 
     code: 'eur' 
 
    }, { 
 
     code: 'usd' 
 
    } 
 
]; 
 
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> 
 
<div ng-app='myApp' ng-controller="ArrayController"> 
 
    <select ng-model="company.currency.code" ng-options="currency.code as (currency.code | uppercase) for currency in currency_list | uppercase"> 
 
</select> 
 
</div>
