p:commandLink无法在新窗口/选项卡中打开页面 [英] p:commandLink fails to open page in new window/tab
问题描述
我正在尝试创建一个链接，以在其他窗口/选项卡中打开新页面，并显示来自支持bean的某些msg，但操作失败，想知道为什么吗?
I'm trying to create a link to open a new page in a different window/tab and display some msg from backing bean but fail to do it, wonder know why?
这是我的xhtml文件:
here is my xhtml file:
<html:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:body>
<h:form id="form66">
<p:commandLink actionListener="#{testing.getMessage}" action="msg.xhtml" target="_blank">get Msg</p:commandLink>
</h:form>
</h:body>
</html>
这是我的Msg.xhtml页面
here is my Msg.xhtml page
<HTML xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<title>testing</title>
</h:head>
<h:body>
<div class="div">
<p:panel>
<f:facet name="header">
testing
</f:facet>
<div class="paddingForPanel">
<h:outputText value="#{testing.msg}" escape="false"/>
</div>
</p:panel>
</div>
</h:body>
</HTML>
这是我的测试文件.
public void getMessage() {
this.msg = "haha";
}
private String msg;
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
上面的代码无法打开新的选项卡/窗口，我尝试如下操作，成功在新选项卡中打开新页面，但味精为空，当我调试时，它成功调用了监听器getMessage，我想知道为什么在msg.xhtml页面中味精为空?
预先感谢....
the code above fail to open a new tab/window, I try to do like below, it success to open the new page in new tab but the msg is empty, when I debug, it got success call the listenner getMessage, I wonder know why the msg is empty in the msg.xhtml page?
Thanks in advance....
<p:commandLink actionListener="#{testing.getMessage}" oncomplete="window.open('msg.xhtml')">broadcast Msg</p:commandLink>
推荐答案
<p:commandLink>有一些ajax问题，请改用<h:commandLink>.
<p:commandLink> has some ajax issues, Use <h:commandLink> instead.
<h:commandLink actionListener="#{testing.printMessage}" action="/Msg.html" target="_blank">get Msg</h:commandLink>
将<p:commandLink>更改为<h:commandLink>，您的代码可以正常工作.
changed <p:commandLink> to <h:commandLink> and your code is working fine.
