JSF - <h:outputText> (escape special chars)

问题

I am trying set 1^®2 in outputText:

<h:outputText value="1&lt;sup&gt;&#174;&lt;sup/&gt;2" escape="false"/>

What is incorrect? I get 2 in uppercase.

回答1:

You can choose one of the following

In your original proposal you had a misplace the / it should be before the sup

<h:outputText value="1&lt;sup&gt;&#174;&lt;/sup&gt;2" escape="false"/>

You can also remove the sup completely (but than your (R) wont be small)

<h:outputText value="1&#174;2" escape="false"/>

Finally you can use it directly without escaping

<h:outputText value="1®2"/>
