JSF commandButton URL参数 [英] JSF commandButton URL parameters

问题描述

我想创建一个导航到其他URL并在URL中传递一些请求参数的按钮. outputLink可以工作，但是我想要一个按钮，commandButton看起来不错，但是我可以传递参数.

I would like to make a button which navigates to a different URL and pass some request parameters through in the URL. The outputLink works but I would like a button, the commandButton looks good but I can pass parameters.

有解决方案吗?

推荐答案

h:commandButton不会触发GET请求，但是会触发POST请求，因此您无法使用它.如果您已经在JSF 2.0上并且目标页面位于相同的上下文中，则可以为此使用h:button:

The h:commandButton doesn't fire a GET request, but a POST request, so you can't use it. If you're already on JSF 2.0 and the target page is in the same context, then you can use the h:button for this:

<h:button value="press here" outcome="otherViewId">
    <f:param name="param1" value="value1" />
    <f:param name="param2" value="value2" />
</h:button>

(此处与h:outputLink一样不需要h:form).这将创建一个转到otherViewId.jsf?param1=value1&param2=value2的按钮.

(no h:form is required here as in h:outputLink). This will create a button which goes to otherViewId.jsf?param1=value1&param2=value2.

但是，如果您还没有使用JSF 2.0，那么最好的办法就是抓住CSS来像按钮一样设置链接的样式.

But if you're not on JSF 2.0 yet, then your best is just to grab CSS to style the link like a button.

<h:outputLink styleClass="button">

类似

a.button {
    display: inline-block;
    background: lightgray;
    border: 2px outset lightgray;
    cursor: default;
}
a.button:active {
    border-style: inset;
}
