ex2_remember_language_cookies

    <script src="Scripts/angular-cookies.js"></script>
    <script src="Scripts/angular-translate-storage-cookie.js"></script>

// Tell the module to store the language in the cookie
$translateProvider.useCookieStorage();

ex3_remember_language_local_storage

این مثال همانند مثال قبل رفتار می‌کند، با این تفاوت که به جای اینکه کلید زبان کنونی را درون کوکی ذخیره کند، آن را درون Local Storage با نام NG_TRANSLATE_LANG_KEY قرار می‌دهد. برای اجرا کافیست اسکریپت‌ها و تکه کد زیر را با موارد مثال قبل جایگزین کنید.

<script src="Scripts/angular-translate-storage-local.js"></script>


// Tell the module to store the language in the local storage
$translateProvider.useLocalStorage();

مثال های ex4_set_a_storage_key  و ex5_set_a_storage_prefix نام کلیدی که برای ذخیره سازی زبان کنونی در کوکی یا Local Storage قرار می‌گیرد را تغییر می‌دهد که به دلیل سادگی از شرح آن می‌گذریم. 

ex6_namespace_support 

translate table در angular-translate قابلیت مفید namespacing را نیز داراست. این قابلیت به ما کمک می‌کند که جهت کپسوله کردن بخش‌های مختلف، ترجمه آنها را با namespace‌های خاص خود نمایش دهیم. به مثال زیر توجه کنید:

            $translateProvider.translations('en_US', {
                "TITLE": "How to use namespaces",
                "ns1": {
                    "HEADER": "A translations table supports namespaces.",
                    "SUBHEADER": "So you can to structurize your translation table well."
                },
                "ns2": {
                    "HEADER": "Do you want to have a structured translations table?",
                    "SUBHEADER": "You can to use namespaces now."
                }
            });

همانطور که توجه می‌کنید بخش ns1 خود شامل زیر مجموعه‌هایی است و ns2 نیز به همین صورت. هر کدام دارای کلید HEADER و SUBHEADER می‌باشند. فرض کنید هر کدام از این بخش‌ها می‌خواهند اطلاعات درون یک section را نمایش دهند. حال به نحوه‌ی فراخوانی این translate tableها دقت کنید:

<!-- section 1: Translate Table Called by ns1 namespace -->    
<h1 translate>ns1.HEADER</h1>
<h2 translate>ns1.SUBHEADER</h2>

<!-- section 2: Translate Table Called by ns2 namespace -->
<h1 translate>ns2.HEADER</h1>
<h2 translate>ns2.SUBHEADER</h2>

به همین سادگی می‌توان تمامی بخش‌ها را با namespace‌های مختلف در translate table قرار داد.

در بخش بعدی (پایانی) شش قابلیت دیگر angular translate که شامل فراخوانی translate table از یک فایل JSON، فراخوانی فایل‌های translate table به صورت lazy load و تغییر زبان بخشی از صفحه به صورت پویا هستند، بررسی خواهند شد.
