Class Html

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, Component, Scope, ComponentCtrl
    public class Html
extends XulElement
    A component used to embed the browser native content (i.e., HTML tags) into the output sent to the browser. The browser native content is specified by setContent(java.lang.String).

    Notice that Html generates HTML SPAN to enclose the embedded HTML tags. Thus, you can specify the style (HtmlBasedComponent.getStyle()), tooltip XulElement.getTooltip() and so on. 

    <html style="border: 1px solid blue"><![CDATA[
 <ul>
  <li>It is in a SPAN tag.</li>
 </ul>
]]></html>

    The generated HTML tags will look like: 

    <SPAN id="xxx" style="border: 1px solid blue">
 <ul>
  <li>It is in a SPAN tag.</li>
 </ul>
</SPAN>

    Since SPAN is used to enclosed the embedded HTML tags, so the following is incorrect. 

    <html><![CDATA[
 <table>
  <tr>
   <td> <-- Incomplete since it is inside SPAN -->
]]></html>

<textbox/>

<html><![CDATA[
   </td>
  </tr>
 </table>
]]></html>

    If you need to generate the HTML tags directly without enclosing with SPAN, you can use the Native namespace, http://www.zkoss.org/2005/zk/native. Refer to ZK Developer's Reference for more information.

    A non-XUL extension.
