GWT i18n，更改metaTag并重新加载应用程序 [英] GWT i18n, change metaTag and reload application

问题描述

我试图国际化我的GWT应用程序。

阅读教程并查看一些示例。

有没有办法在不添加url的情况下更改语言标记locale = de

我的目标是在菜单登录屏幕上，用户选择语言，然后重新加载。
我设法通过将语言环境添加到网址来实现这一点[丑陋的方式给我]

我读到meta标签在Html文件中。
所以我试着把它放在html文件
中，它用这种语言加载，但我不能再改变语言。

只有使用meta标签才有可能使语言变得更大？

在代码中，我可以阅读和修改元标记值，但当我刷新我所做的更改丢失

  NodeList< Element> tags = Document.get（）。getElementsByTagName（meta）; （int i = 0; i< tags.getLength（）; i ++）{
 MetaElement metaTag =（（MetaElement）tags.getItem（i））; 
 System.out.println（metaTag.getName（）=+ metaTag.getName（））; 
 System.out.println（metaTag.getContent =+ metaTag.getContent（））; 
 if（metaTag.getName（）。equals（gwt：property））{
 metaTag.setContent（locale = de）; 
} 
} 
 Window.Location.reload（）; 
  

解决方案

您可以使用cookie读取/

在您的.gwt.xml文件中

 < set-configuration-property name =locale.cookie
 value =GWT_LOCALE/> 
  

在您的java代码中读取语言环境信息

  final String cookieName = LocaleInfo.getLocaleCookieName（）; 
字符串cookie = Cookies.getCookie（cookieName）; 
  

在您的java代码中编写语言环境信息

< pre $ private void setLocaleCookie（String locale）
{
final String cookieName = LocaleInfo.getLocaleCookieName（）;
if（cookieName！= null）
{
Date expires = new Date（）;
expires.setYear（expires.getYear（）+ 1）;
Cookies.setCookie（cookieName，locale，expires）;
}
if（！control）
{
com.google.gwt.user.client.Window.Location.reload（）;
}
}

I'm trying to internationalize my GWT application.

I read the tutorials and see some examples.

Is there a way to do the language change without adding the url the tag "?locale=de"

My objective is at the menu login screen, the user selects the languague, and then it reloads. I managed to do that with the adding of the locale to the url.[Ugly way to me]

I was reading that there is possible with meta tags in Html file. So i tryed to put that in the html file

It loads in that language, but i can't change no more the language.

Is possible to chage the language only using meta tags?

In code, i can read and chage the meta tag value but when i refresh the change i made is lost

    NodeList<Element> tags = Document.get().getElementsByTagName("meta");
    for (int i = 0; i < tags.getLength(); i++) {
        MetaElement metaTag = ((MetaElement) tags.getItem(i));
        System.out.println("metaTag.getName() = " + metaTag.getName());
        System.out.println("metaTag.getContent = " + metaTag.getContent());
        if (metaTag.getName().equals("gwt:property")) {
            metaTag.setContent("locale=de");
        }
    }
    Window.Location.reload();

解决方案

You can use cookies to read/write information about your locale instead of meta tag or url.

In your .gwt.xml file

<set-configuration-property name="locale.cookie"
    value="GWT_LOCALE" />

In you java code to read locale info

final String cookieName = LocaleInfo.getLocaleCookieName();
String cookie = Cookies.getCookie( cookieName );

In you java code to write locale info

private void setLocaleCookie( String locale )
{
    final String cookieName = LocaleInfo.getLocaleCookieName();
    if ( cookieName != null )
    {
        Date expires = new Date();
        expires.setYear( expires.getYear() + 1 );
        Cookies.setCookie( cookieName, locale, expires );
    }
    if ( !control )
    {
        com.google.gwt.user.client.Window.Location.reload();
    }
}
