JSF的语言切换器和Ajax更新 [英] JSF Language switcher and ajax update
问题描述
此问题是后续 - 起来老语言切换器实现的JSF 2 。
This question is a follow - up of the older Language switcher implementation in JSF 2.
问题的实质仍然是有效的，尽管PrimeFaces已经发布了一些较新的版本，而我的JSF的知识比以前好一点。
The substance of the question is still valid, although PrimeFaces has released some newer builds, and my JSF knowledge is a bit better than before.
要总结一下，我有一个XHTML页面，完全Ajax化。
To summarize, I have a single xhtml page, fully ajaxified.
语言切换器是这样的：
<h:form id="selectLanguage" >
<p:commandLink action="#{languageSwitcher.setLanguage('it')}" rendered="#{languageSwitcher.language!='it'}" >
<h:graphicImage library ="images" name="it.gif" title="it" />
</p:commandLink>
<p:commandLink action="#{languageSwitcher.setLanguage('en')}" rendered="#{languageSwitcher.language!='en'}" >
<h:graphicImage library ="images" name="en.gif" title="en" />
</p:commandLink>
</h:form>
我想，当 是 选择，只有在 连接 标志显示，反之亦然。我想，在网页上的所有东西与资源包的翻译更新。
I want that when it is chosen, only the en flag is displayed, and viceversa. And I want that all the stuff in the web page is updated with the Resource Bundle translations.
在特别的，我有一些号码：对话框（胡）的标题属性需要被更新。
对话框的形式是每个对话框里面：
In particular, I have some p:dialogS whose header attributes need to be updated as well.
The dialog forms are inside each dialog:
<p:dialog header="#{msgs.myHeader}" ... >
<h:form .... />
</p:dialog >
在页面的其余部分是一个＆LT;电话号码：布局＆GT; 包含一些layoutUnits。每个 layoutUnit 包含了需要翻译以及其它组件的形式。
The rest of the page is a <p:layout> containing some layoutUnits. Each layoutUnit contains a form with other components that need to be translated as well.
LanguageSwitcher是 SessionScoped JSF托管Bean 。
LanguageSwitcher is a SessionScoped JSF Managed Bean.
我已经尝试了所有通过以下方式：
I have tried all of the following ways:
-
＆LT; F：AJAX渲染=@所有/＆GT;的P的内侧：commandLink括号 -
更新=@所有的里面的属性号码：commandLink -
＆LT;电话号码：AJAX更新=@所有/＆GT;在号码：commandLink括号
<f:ajax render="@all" />inside thep:commandLinkbracesupdate="@all"attribute insidep:commandLink<p:ajax update="@all" />inside thep:commandLinkbraces
不幸的是，他们没有工作。
Unfortunately, none of them works.
我曾尝试与 @all ，虽然我可插入的表格的ID，他们没有那么多。问题是，在对话框标题以这种方式不被更新。
I have tried with @all, although I am available to insert the ids of the forms, they are not so many. Problem is that the dialog headers are not updated in this way.
我使用PrimeFaces 3.4.1 - Mojarra 2.1.13
I am using PrimeFaces 3.4.1 - Mojarra 2.1.13
推荐答案
在更新=@所有的所有PrimeFaces版本到现在为止（3.4.2）是已知在IE中失败。任何JavaScript code随着Ajax响应传递不正确初始化。
The update="@all" of all PrimeFaces versions until now (3.4.2) is known to fail in IE. Any JavaScript code delivered along with the ajax response isn't been initialized properly.
这是在此PrimeFaces论坛主题并报告为问题4731 。
直到他们解决这个问题，最好的办法是通过加载下面的一段JavaScript的每个视图，它（可能）包含一个更新要解决它=@所有的命令：
Until they fix it, your best bet is to workaround it by loading the following piece of JavaScript on every view which (possibly) contains an update="@all" command:
var originalPrimeFacesAjaxResponseFunction = PrimeFaces.ajax.AjaxResponse;
PrimeFaces.ajax.AjaxResponse = function(responseXML) {
var newViewRoot = $(responseXML.documentElement).find("update[id='javax.faces.ViewRoot']").text();
if (newViewRoot) {
$('head').html(newViewRoot.substring(newViewRoot.indexOf("<head>") + 6, newViewRoot.indexOf("</head>")));
$('body').html(newViewRoot.substring(newViewRoot.indexOf("<body>") + 6, newViewRoot.indexOf("</body>")));
} else {
originalPrimeFacesAjaxResponseFunction.apply(this, arguments);
}
};
在由＆LT加载的JS文件的香味提供此; H：outputScript目标=头＆GT; 在＆LT; H：身体GT; ，以执行正确的加载顺序
Provide this in flavor of a JS file which is loaded by <h:outputScript target="head"> inside the <h:body> in order to enforce the right loading order.
<h:body>
<h:outputScript name="script.js" target="head" />
...
</h:body>
