在dataTable中时，f:verbatim标记停止工作

本文介绍了在dataTable中时，f:verbatim标记停止工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我将其发布到PrimeFaces用户论坛上，但是我认为他们太忙了，无法研究它，所以我想我可以在这里尝试.

I posted this to the PrimeFaces user forum but I think they are too busy to look into it, so I thought I would try here.

我在其中包含标记的服务器端字符串，所以当我要呈现它时，我可以这样做:

I have server-side string that has markup in it, so when I want it rendered I do this:

            <p:panel>                    
                <f:verbatim>
                    #{daBean.markedUpString}
                </f:verbatim>
            </p:panel>

这很好用，但是如果 p:dataTable 中使用了相同的标签，则不管该标签是否带有 p:panel .呈现的是一个 div class ="ui-dt-c" 元素，其中没有任何内容.为了进行测试，如果我删除了 f:verbatim 标记，则标记后的文本将被转义并呈现.

This works fine, but not if the same tag is used inside a p:dataTable -- either with or without the p:panel enclosure. What gets rendered is a div class="ui-dt-c" element with nothing in it. To test, if I take out the f:verbatim tag the marked-up text gets escaped and rendered.

我不知道是否应该将其视为错误，但是没有人知道解决方法吗?这是PrimeFaces 3.0.M3的版本.

I don't know if this should be considered a bug or not, but does anyone know of a work-around for this? This is with PrimeFaces 3.0.M3.

推荐答案

<f:verbatim>标记旨在容纳纯文本文本/HTML，而不是JSF组件或EL表达式.当无法在JSF组件之间内联纯文本/HTML时，该标记是JSF 1.0/1.1时代的遗留物.该标签在JSF2中已弃用.您不再需要它.

The <f:verbatim> tag is intented to hold plain text/HTML, not JSF components nor EL expressions. The tag is a leftover from JSF 1.0/1.1 ages when it was not possible to inline plain text/HTML between JSF components. The tag is deprecated in JSF2. You do not need it anymore.

因此，您的具体功能要求是显示未转义的托管Bean中的一些HTML字符串.为此，您应该将<h:outputText>与escape="false"一起使用.

Your concrete functional requirement is thus displaying some HTML string from a managed bean unescaped. For that you should use <h:outputText> with escape="false".

<h:outputText value="#{daBean.markedUpString}" escape="false" />
