Question

我有一个链接，可以在xhtml中从lang 1切换到lang 2：

<p:commandLink value="#{msgs['home.french']}" id="frenchLink" 
     rendered="#{mainBean.changeLanguage.getLanguage() ne 'fr'}"    
    actionListener="#{mainBean.refreshPage}" ajax="false">  
  <f:param name="selectedLanguage" value="fr"/>
</p:commandLink>

<p:commandLink value="#{msgs['home.english']}" id="englishLink" r
    endered="#{mainBean.changeLanguage.getLanguage() ne 'en'}"  actionListener="#{mainBean.refreshPage}" ajax="false">
    <f:param name="selectedLanguage" value="en"/>
</p:commandLink>

并在mainBean中，

public void refreshPage(ActionEvent event){
        FacesContext context = FacesContext.getCurrentInstance(); 
        String language = context.getExternalContext().getRequestParameterMap().get("selectedLanguage");
        changeLanguage = new ChangeLanguage();
        ChangeLanguage.setLanguage(language);
        String viewId = context.getViewRoot().getViewId(); 
        ViewHandler handler = context.getApplication().getViewHandler(); 
        UIViewRoot root = handler.createView(context, viewId); 
        root.setViewId(viewId); 
        context.setViewRoot(root);
        context.renderResponse();
}

始终获取未捕获的TypeError：对象＃在primefaces.js上没有方法'replace'

只有当我切换到法语和具有selectOneMenu，对话框的页面时，才会弹出这些问题。

对此有任何指示赞赏。

App使用Jsf 2.0，Primefaces 3.5

在yor faces-config.xml中定义默认语言

 <application>
       <locale-config>
            <default-locale>en</default-locale>
       </locale-config>
 </application>

建议您的bean为@SessionScoped，然后考虑创建一个bean来控制系统的位置。

在Bean中创建此属性。

private static Map<String,Locale> countries;
    static{
        countries = new HashMap<String,Locale>();
        countries.put("fr", Locale.FRANCE);
        countries.put("en", Locale.ENGLISH);
    }

添加更改语言的方法。

public void changeLanguage(){
        FacesContext context = FacesContext.getCurrentInstance(); 
        String language = context.getExternalContext().getRequestParameterMap().get("selectedLanguage");
        context.getViewRoot().setLocale(countries.get(language));
}

在您的视图中（xhtml）：

<p:commandLink value="#{msgs['home.french']}" id="frenchLink" 
    rendered="#{mainBean.changeLanguage.getLanguage() ne 'fr'}"    
    actionListener="#{mainBean.changeLanguage}" ajax="false" 
    oncomplete="javascript:location.reload(true)">  
  <f:param name="selectedLanguage" value="fr"/>
</p:commandLink>

<p:commandLink value="#{msgs['home.english']}" id="englishLink"
    rendered="#{mainBean.changeLanguage.getLanguage() ne 'en'}"  actionListener="#{mainBean.changeLanguage}" ajax="false" 
    oncomplete="javascript:location.reload(true)">
    <f:param name="selectedLanguage" value="en"/>
</p:commandLink>

未捕获的TypeError：对象＃<object>在primefaces.js </object>上没有方法'replace'
