我知道这篇文章,我仔细检查了那里的所有可能性。
我在 Glassfish 3 上使用带有 Mojarra 实现的 JSF 2.0。
我正在尝试使用两个简单<h:commandLink>
的标签来更改应用程序语言。这是.xhtml
页面:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>
<h:outputText value = "#{appMessage['page.welcome']}" />
</title>
<f:metadata>
<f:event type = "preRenderView" listener = "#{sessionController.changeLanguage}" />
</f:metadata>
</h:head>
<h:body>
<h1><h:outputText value = "#{appMessage['text.slide.welcome']}" /></h1>
<h:form id = "fm-language">
<h:commandLink action = "#{sessionController.changeLanguage('en')}" value = "#{appMessage['link.english']}" />
<h:commandLink action = "#{sessionController.changeLanguage('de')}" value = "#{appMessage['link.german']}" />
</h:form>
</h:body>
这是 HTML 代码:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>The Maze Project</title>
</head>
<body>
<h1>Welcome</h1>
<form id="fm-language" name="fm-language" method="post" action="/maze/welcome.xhtml" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="fm-language" value="fm-language" />
<script type="text/javascript" src="/maze/javax.faces.resource/jsf.js.xhtml?ln=javax.faces">
</script>
<a href="#" onclick="mojarra.jsfcljs(document.getElementById('fm-language'),{'fm-language:j_idt13':'fm-language:j_idt13'},'');return false">English</a>
<a href="#" onclick="mojarra.jsfcljs(document.getElementById('fm-language'),{'fm-language:j_idt15':'fm-language:j_idt15'},'');return false">Deutsch</a>
<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="8038443616162706480:-1387069664590476821" autocomplete="off" />
</form>
</body>
当按下 commandLink 时,什么都没有发生。没有向服务器发送请求,并引发以下 Java 脚本错误:
mojarra 未定义
bean 方法被正确调用并在应用程序的其余部分中正常工作。
