Class JQueryRenderPatch

java.lang.Object

org.zkoss.zkplus.liferay.JQueryRenderPatch

All Implemented Interfaces:

org.zkoss.zk.ui.sys.PageRenderPatch

Direct Known Subclasses:

JQueryRenderCachedPatch, NonRootContextJQueryRenderPatch

public class JQueryRenderPatch
extends Object
implements org.zkoss.zk.ui.sys.PageRenderPatch

Used to patch the rendering result of a ZK portlet for Liferay. When using ZK portlets with Liferay under Internet Explorer, we have to delay the processing at the client a bit.

To use it, you have to specify a library property called ""org.zkoss.zk.portlet.PageRenderPatch.class" with this class's name ("org.zkoss.zkplus.liferay.JQueryRenderPatch").

You can further control the behavior of this patch by use of a library property called "org.zkoss.zkplus.liferary.jQueryPatch" (refer to JQUERY_PATCH for details).
