jQuery之前端国际化jQuery.i18n.properties
-
jQuery.i18n.properties采用.properties文件对JavaScript进行国际化。jQuery.i18n.properties插件首先加载默认的资源文件(filename.properties),然后加载针对特定语言环境的资源文件(filename_zh.properties),这就保证了在未提供某种语言的翻译时,默认值始终有效。
-
filename的命名方式:
filename.properties(默认定义)
filename_language.properties(自定义语言)
filename_language_country.properties(自定义语言加国家) -
应用说明:
首先引入jQuery.i18n.properties插件:<script type="text/javascript" src="${basePath}/static/plugin/jqueryi18n/jquery.i18n.properties.min.js"></script>
/** * Load and parse message bundle files (.properties), * making bundles keys available as javascript variables. * * i18n files are named <name>.js, or <name>_<language>.js or <name>_<language>_<country>.js * Where: * The <language> argument is a valid ISO Language Code. These codes are the lower-case, * two-letter codes as defined by ISO-639. You can find a full list of these codes at a * number of sites, such as: http://www.loc.gov/standards/iso639-2/englangn.html * The <country> argument is a valid ISO Country Code. These codes are the upper-case, * two-letter codes as defined by ISO-3166. You can find a full list of these codes at a * number of sites, such as: http://www.iso.ch/iso/en/prods-services/iso3166ma/02iso-3166-code-lists/list-en1.html * * Sample usage for a bundles/Messages.properties bundle: * $.i18n.properties({ * name: 'Messages', * language: 'en_US', * path: 'bundles' * }); * @param name (string/string[], optional) names of file to load (eg, 'Messages' or ['Msg1','Msg2']). Defaults to "Messages" * @param language (string, optional) language/country code (eg, 'en', 'en_US', 'pt_BR'). if not specified, language reported by the browser will be used instead. * @param path (string, optional) path of directory that contains file to load * @param mode (string, optional) whether bundles keys are available as JavaScript variables/functions or as a map (eg, 'vars' or 'map') * @param cache (boolean, optional) whether bundles should be cached by the browser, or forcibly reloaded on each page load. Defaults to false (i.e. forcibly reloaded) * @param encoding (string, optional) the encoding to request for bundles. Property file resource bundles are specified to be in ISO-8859-1 format. Defaults to UTF-8 for backward compatibility. * @param callback (function, optional) callback function to be called after script is terminated */ jQuery.i18n.properties({ name : 'filename', //资源文件名称 path : '${contentsPath}/static/i18n/', //资源文件路径 mode : 'map', //用Map的方式使用资源文件中的值 language : 'zh', callback : function() {//加载成功后设置显示内容 console.info($.i18n.prop('key'));// key 为properties文件中定义的键值对相应的key,这样既数据key对应的value } }); // filename.properties中定义的类容 // name=zivs_en // filename_zh.properties中定义的类容 // name=zivs_zh //使用 $("#my_input").val($.i18n.prop('name'));//获取key=name的value: $.i18n.prop('name') ```
- 总结:
若使用的filename.properties是项目的resource目录中已定义的话,需要将相应.properties文件copy一份到项目static目录(resource目录是在Service端,受保护,Client端不能直接获取),这样也来同一份properties文件就会存在两份。

模板(Freemarker)嵌入使用
将资源国际化message定义成一个jQuery变量(在FreeMarker模板中),在将变量通过模板嵌入页面。这样页面就会存在一个动态引入的变量。
1.定义模板变量:
<#macro orderDetailI18n> var i18n_message = { serviceException : "<@spring.message code="sys.hint.serviceException"/>",// <@spring.message code="sys.hint.serviceException"/>Spring i18n 的页面书写方式 order_detail : "<@spring.message code="order.detail.detail"/>", confirmText : "<@spring.message code="order.btn.confirmText"/>", confirmNoisNotNull : "<@spring.message code="order.detail.win.confirmNoisNotNull"/>" }; </#macro>
2.页面引入模板变量:
<#--引入定义的 i18n_message 资源数据--> <@order_detail_i18n_data.orderDetailI18n/>
3.获取值:
<#--或缺 i18n_message 定义的key为 serviceException 的值--> console.info(i18n_message.serviceException);
4.总结: filename.properties在系统中只存在唯一一份,保证了数据的唯一性。
