[英]<f:viewParam> not working when using <ui:composition template>
[英]<f:ajax event> not working with <ui:composition template=“”>
我有一个奇怪的问题,我不知道主要原因,我有这些登录页面,该页面使用<f:ajax event="">
来验证用户名和密码:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head></h:head>
<h:body>
<h:form>
<h:panelGrid columns="3">
Name:
<h:inputText id="name" value="#{validateBean.name}"
validator="#{validateBean.validateName}">
<f:ajax event="blur" render="nameError" />
</h:inputText>
<h:message for="name" id="nameError" style="color:red" />
Password:
<h:inputText id="password" value="#{validateBean.password}"
validator="#{validateBean.validatePassword}">
<f:ajax event="blur" render="passwordError" />
</h:inputText>
<h:message for="password" id="passwordError" style="color:red" />
<h:commandButton value="Login" action="# {validateBean.login}" />
</h:panelGrid>
这些JSF可以正常工作,但是当我将上述相同组件放在<ui:composition template="">
以便将这些页面与模板一起使用时,就会出现问题
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
<ui:composition template="/WEB-INF/Templates/BasicTemplate.xhtml">
<ui:define name="content">
<center>
<h:form>
<h:panelGrid columns="3">
Name:
<h:inputText id="name" value="#{validateBean.name}"
validator="#{validateBean.validateName}">
<f:ajax event="blur" render="nameError" />
</h:inputText>
<h:message for="name" id="nameError" style="color:red" />
Password:
<h:inputText id="password" value="#{validateBean.password}"
validator="# {validateBean.validatePassword}">
<f:ajax event="blur" render="passwordError" />
</h:inputText>
<h:message for="password" id="passwordError" style="color:red" />
<h:commandButton value="Login" action="# {validateBean.login}" />
</h:panelGrid>
</h:form>
</center>
</ui:define>
</ui:composition>
</html>
为了更加清晰,这是jsf模板页面:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets">
<head>
<title><ui:insert name="title">Default title</ui:insert></title>
</head>
<body>
<div id="header">
<ui:insert name="header">
<ui:include src="header.xhtml"/> // normal page contains plain text
</ui:insert>
</div>
<div id="content">
<ui:insert name="content">
Content area. See comments below this line in the source.
</ui:insert>
</div>
<div id="footer">
<ui:insert name="footer">
<ui:include src="footer.xhtml"/> // normal page contains plain text
</ui:insert>
</div>
</body>
</html>
当我尝试后一种方法时,AJAX动作根本不触发,请任何人向我解释为什么会发生这种情况?
您在主模板中使用了<head>
而不是<h:head>
。 这样,JSF无法自动包含ajax工作所需的jsf.js
JavaScript文件。
相应地修复它:
<html ...>
<h:head>
...
</h:head>
<h:body>
...
</h:body>
</html>
