JSF display HTML comment

问题

I am using JSF 2.0 and have defined property javax.faces.FACELETS_SKIP_COMMENTS to skip comments in JSF code because there is a lot of other code, deveploping comments etc. But I need to print some HTML comments into client's browser eg. for defining alternative conditioned stylesheet for other browsers.

Please is there any way how to do it? Because all my attempts failed.

回答1:

Use <ui:remove> to remove comments instead of the context parameter.

回答2:

This is crude but it does work (under JSF 1.2 anyway not tested in 2)

<h:outputText value="&lt;!--" escape="false" /> My comment <h:outputText value="--&gt;" escape="false" />

回答3:

Maybe you could use f:verbatim:

<f:verbatim>&lt;!--[if lt IE 7]&gt;
    Something just for lower than IE7
&lt;![endif]--&gt;</f:verbatim>

回答4:

Based on @Juan's and @reevesy's ideas is this one:

<f:verbatim>&lt;!--
    This is a happy HTML comment :)
--&gt;</f:verbatim>

Which will render:

<!--
    This is a happy HTML comment :)
-->
