AngularJS $locale服务未正确返回法语（瑞士）语言问题求助

Hey there, let's break down what might be going wrong with your AngularJS $locale setup for French (Switzerland) locale!

First off, a super common gotcha with AngularJS's $locale service: it doesn't automatically detect your browser's locale. Instead, it returns the configuration from the locale file you've loaded into your app. If you're not seeing the correct fr-CH values, chances are you haven't loaded the corresponding locale file, or there's an issue with how you're loading it.

Here's how to fix and verify your setup:

1. Make sure you're loading the fr-CH locale file #

AngularJS only includes a default locale (usually en-US) out of the box. To use fr-CH, you need to grab the angular-locale_fr-ch.js file (from the AngularJS distribution or CDN) and load it after the core AngularJS script.

Example HTML setup:

<script src="path/to/angular.min.js"></script>
<!-- Load the fr-CH locale file next -->
<script src="path/to/angular-locale_fr-ch.js"></script>

2. Verify your $locale usage in code #

Double-check that you're accessing the right properties from $locale. For example, to confirm the locale ID, you can log or display $locale.id:

angular.module('myLocaleApp', [])
  .controller('LocaleTestCtrl', function($scope, $locale) {
    // This should return 'fr-ch' if the locale file is loaded correctly
    $scope.localeId = $locale.id;
    // You can also check other locale-specific values, like date formats
    $scope.shortDateFormat = $locale.DATETIME_FORMATS.shortDate;
  });

3. Common mistakes to check #

• Wrong load order: If you load the locale file before AngularJS core, it won't register properly. Always load Angular first, then the locale file.
• Missing locale file: If you get a 404 for the locale file in your browser's dev tools, double-check the file path or use a CDN link for the correct file.
• Misunderstanding $locale's purpose: Remember, $locale doesn't read your browser's settings automatically. If you want to match the browser's locale, you'll need to add extra code to detect navigator.language and dynamically load the corresponding locale file (like converting fr-CH to fr-ch for the filename, then creating a script tag to load it).

If you've done all this and still aren't seeing the right results, share a snippet of your test code and we can dig deeper!
