This means that disabled input elements do not get submitted with the form. This could be needed where more than one submit buttons exist on a form. Javascript onclick can be used to set the other submit buttons to "disabled", and so only the clicked submit button gets submitted.

Popups

You could also display the result as a popup:

<portlet:namespace/>submitEntry = function(form) { var popup = Liferay.Popup({modal: true,width:300}); AjaxUtil.submit(form, popup); } <portlet:namespace/>updateEntry = function(url) { var popup = Liferay.Popup({modal: true,width:300}); AjaxUtil.update(url, popup); }

You could also display a popup without going to the server for your response:

<portlet:namespace/>showPopup = function(form) { var html = '<input class="button" id="ok_btn" value="OK" onclick="Liferay.Popup.close(this);" type="button">'; var popup = Liferay.Popup({ title: "My Title", message: html, modal: true, width:300 }); }

Liferay.Popup({}) had the following options available:

/** * OPTIONS: * modal (boolean) - show shaded background * message (string|object) - default HTML/object to display * noCenter (boolean) - prevent re-centering * height (int) - starting height of message box * width (int) - starting width of message box * onClose (function) - executes after closing */

There were five (5) window states available within Liferay, for use in generating action URLs, for example:

<portlet:actionURL windowState="<%= LiferayWindowState.NORMAL.toString() %>">

The class com.liferay.portal.kernel.portlet.LiferayWindowState extends javax.portlet.WindowState (see javadoc here)

The two which Liferay provided in addition to the javax ones are LiferayWindowState.POP_UP and LiferayWindowState.EXCLUSIVE. The one to use in combination with javascript Liferay.Popup() and AjaxUtil.update() is LiferayWindowState.EXCLUSIVE, as this renders purely the result of the portlet jsps without any extra HTML or other data added. LiferayWindowState.POP_UP is designed for use with iframes and non-ajax popups of the <a href="" target="_blank"/> type (i.e. a new browser window) and thus has various header and footer HTML added which is inappropriate for the ajax style popup.
