Ajax in Liferay 5

Form submission #

As of Liferay 5 , form submission is done using JQuery and the LiferayWindowState.EXCLUSIVE window state , that will return just the HTML snippet produced by the portlet.

The following code sample demonstrates the pattern of progressive enhancement where the form will submit without Javascript as well as with (To work with less capable devices .etc.

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="com.liferay.portal.kernel.portlet.LiferayWindowState" %>

<div id="<portlet:namespace />lgoUsers">
<script type="text/javascript">
jQuery(function($){

var <portlet:namespace/>form = $('#'+'<portlet:namespace />fm');

<portlet:namespace/>form.bind("submit",function(event){
	   event.preventDefault();
	   var inputs = $("input, textarea, select", <portlet:namespace/>form);
	   var url = '<portlet:actionURL windowState="<%= LiferayWindowState.EXCLUSIVE.toString() %>"/>' + "&" + inputs.serialize(); // see note below
	   $('#<portlet:namespace />lgoUsers').load(url);
});

});
</script>

<form
action="<portlet:actionURL/>"
method="post"
name="<portlet:namespace />fm"
id="<portlet:namespace />fm">

<input name="<portlet:namespace />sn" type="text" value="<c:out value="${sn}"/>" />
<input type="submit" name="<portlet:namespace />sm" value="Search" />
</form>
<ul>
<c:forEach items="${users}" var="user">
	<li><c:out value="${user}"/></li>
</c:forEach>
</ul>
</div>

BUG:
jQuery('#'+'<portlet:namespace />fm');
- called before form is defined in HTML... Quick fix: move javascript block after form definition.

What if you have multiple Ajax calls on the same page? How do you make the URL? Would you call multiple backend beans? Or, if you called the same backend bean, how would you handle the logic in the bean?

Last version of this wiki is unreadable. Version 1.3 looks fine.
