html代码如下：

{% csrf_token %}
{% get_language_info_list for LANGUAGES as languages %}
{% for language in languages %}
    
    
        {% if language.code == "zh-cn" %}
        简体
        {% else %}
        Eng
        {% endif %}
    
    
 {% endfor %}

js代码：

$('.change_language').click(function(e){
           e.preventDefault();
           $('#language').val($(this).attr('lang_code'));
           $('#change_language_form').submit();
           return false;
       }
   );

django settings.py设置如下：

。。。。。。。。。。。。。。。。。

USE_I18N = True

# If you set this to False, Django will not format dates, numbers and
# calendars according to the current locale.

USE_L10N = True
ugettext = lambda s: s

LANGUAGES = (
    ('zh-cn', ugettext('Chinese')),
    ('en', ugettext('English')),
)

MIDDLEWARE_CLASSES = (
    'middleware.createuserinfo.CreateUserInfoMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.cache.UpdateCacheMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.middleware.transaction.TransactionMiddleware',
    'djangobb_forum.middleware.LastLoginMiddleware',
    'djangobb_forum.middleware.UsersOnline',
)

。。。。。。。。。。。。。。。。。。。。。。。。。。

djangoz中urls.py设置加入了

url(r'^i18n/', include('django.conf.urls.i18n'))
