p:commandLink不会重定向到新页面吗? [英] p:commandLink won't redirect to new page?
问题描述
我正在使用JSF2和GlassFish，PrimeFaces 2.1.
I'm using JSF2 and GlassFish, PrimeFaces 2.1.
此方法有效，showCreateProfile()方法被命中，该方法返回"profileForm"，浏览器重定向到该页面:
This works, showCreateProfile() method gets hit, and the method returns "profileForm" and the browser redirects to that page:
<h:commandLink action="#{profileHandler.showCreateProfile}" value="#{msg.menu_createNewProfile}" />
但是，这不起作用，showCreateProfile()方法被命中，并且该方法返回"profileForm"，但浏览器未重定向到页面.我没有运气就尝试了三种不同的方法:
However, this doesn't work, showCreateProfile() method get hits, and the method returns "profileForm" but the browser does not redirect to the page. I tried three different things with no luck:
<p:commandLink action="#{profileHandler.showCreateProfile}" value="#{msg.menu_createNewProfile}" />
<p:commandLink action="#{profileHandler.showCreateProfile}" value="#{msg.menu_createNewProfile}" ajax="false" />
<p:commandLink action="#{profileHandler.showCreateProfile}" value="#{msg.menu_createNewProfile}" ajax="false" immediate="true"/>
有什么想法我在做什么错吗?
Any ideas what I'm doing wrong?
推荐答案
Primefaces的p:commandLink默认情况下会触发ajax请求.它不会返回完整的HTTP响应，而仅返回必须由JS在HTML DOM树中更新的部分HTTP响应.
The Primefaces' p:commandLink fires by default an ajax request. It does not return a whole HTTP response, but only a partial HTTP response which has got to be updated in HTML DOM tree by JS.
您基本上有两种选择:
-
通过
ajax="false"属性禁用Ajax.然后它将触发正常的HTTP请求.
Disable ajax by
ajax="false"attribute. It'll then fire a normal HTTP request.
通过update="clientid"属性更新(重新渲染)部分内容(在同一页面上！).您可以使用rendered属性来控制内容的呈现.
Update (re-render) the partial content (on the same page!) by update="clientid" attribute. You can use rendered attribute to control the rendering of content.
如果两个都不起作用，则问题出在其他地方.由于h:commandLink有效且p:commandLink的操作方法也已执行，因此这仅意味着您在尝试ajax="false"时未运行您认为正在运行的代码.验证，保存，重建，重新部署，重新启动.
If neither works, then the problem lies somewhere else. Since the h:commandLink works and the action method of p:commandLink also get executed, then it can only mean that you're not running the code you think you're running while trying the ajax="false". Verify, save, rebuild, redeploy, restart.
