问题描述

我想在JSF页面中创建命令按钮.当我按下它时，我想打开一个新页面并使用http发送一个值.我测试了这个h:commnadButton，但是它不起作用.

I want to create command button in JSF page. When I press it I want to open a new page and send a value using using the http. I tested this h:commnadButton but it's not working.

<h:commandButton id="lnkHidden" value=" Edit User " action="EditAccountProfile.jsf">
 <f:param name="id" value="#{item.userid}" />
</h:commandButton>

推荐答案

h:commandButton is for submitting forms, usually executing actions in the server.

使用 h:button 用于简单导航:

Use h:button for simple navigation:

<h:button id="lnkHidden" value=" Edit User " outcome="EditAccountProfile.jsf">
 <f:param name="id" value="#{item.userid}" />
</h:button>

这将生成普通的HTML <input type="button" onclick="window.location.href=/correct/path/to/EditAccountProfile.jsf" />，无需HTTP POST.

This will generate a normal HTML <input type="button" onclick="window.location.href=/correct/path/to/EditAccountProfile.jsf" />, no HTTP POST needed.
