WebGL animation inside a Liferay 6.2 popup
Hello, here is my second post, where a 3D animation is shown inside a Liferay 6.2 popup.
WebGL is a Javascript API for rendering interactive graphics within any compatible web browser without installing any additional plug-in. WebGL is completely integrated into all the web standards allowing the rendering of GPU accelerated 3D effects as a part of a web page canvas. WebGL elements can be mixed with other HTML elements, so it can be perfectly used inside a Liferay popup. WebGL programs consist of control code written in Javascript and shader code that is executed on a computer's Graphics Processing Unit (GPU).

Sample popup in Liferay 6.2 with close button
Hello! To start with this blog I will publish the code for a
liferay 6.2 popup.
Liferay 6.2 uses the new AUI 2.0 version. When this versión
of Liferay was developed some AUI old modules became deprecated.
The following is sample code for a Liferay 6.2 popup with a close button.
Portlet view jsp code:
<aui:script>
function showPopup() {
AUI().use( 'aui-io',
'aui-dialog',
function(A) {
Liferay.Util.openWindow(
{
dialog: {
centered: true,
destroyOnClose: true,
cache: false,
width: 500,
height: 300,
modal: true
},
title: 'Sample Popup',
id:'<portlet:namespace/>popUpDialog',
uri:'<%=dialogUrl.toString()%>'
});
Liferay.provide(
window,
'<portlet:namespace/>closePopup',
function(popupIdToClose) {
var popupDialog = Liferay.Util.Window.getById(popupIdToClose);
popupDialog.destroy();
},
['liferay-util-window']
);
});
}
</aui:script>
<div>
<h1>AUI Popup</h1><br/>
<aui:button id="dialogButton" value="Show popup" onClick="showPopup();"> </aui:button>
</div>
function showPopup() {
AUI().use( 'aui-io',
'aui-dialog',
function(A) {
Liferay.Util.openWindow(
{
dialog: {
centered: true,
destroyOnClose: true,
cache: false,
width: 500,
height: 300,
modal: true
},
title: 'Sample Popup',
id:'<portlet:namespace/>popUpDialog',
uri:'<%=dialogUrl.toString()%>'
});
Liferay.provide(
window,
'<portlet:namespace/>closePopup',
function(popupIdToClose) {
var popupDialog = Liferay.Util.Window.getById(popupIdToClose);
popupDialog.destroy();
},
['liferay-util-window']
);
});
}
</aui:script>
<div>
<h1>AUI Popup</h1><br/>
<aui:button id="dialogButton" value="Show popup" onClick="showPopup();"> </aui:button>
</div>
Popup jsp code:
<portlet:actionURL name="helloFunction" var="helloFunctionUrl">
<portlet:param name="mvcPath" value="/popup.jsp"/>
</portlet:actionURL>
<aui:script>
function closeThis(){
Liferay.Util.getOpener().<portlet:namespace />closePopup('<portlet:namespace />popUpDialog');
}
</aui:script>
<form name="<portlet:namespace/>fm" action="<%=helloFunctionUrl%>" method="post">
<h1>Sample popup</h1>
<aui:button type="submit" value="Call function" />
<aui:button name="close" value="close" onClick="closeThis();"/>
</form>
<portlet:param name="mvcPath" value="/popup.jsp"/>
</portlet:actionURL>
<aui:script>
function closeThis(){
Liferay.Util.getOpener().<portlet:namespace />closePopup('<portlet:namespace />popUpDialog');
}
</aui:script>
<form name="<portlet:namespace/>fm" action="<%=helloFunctionUrl%>" method="post">
<h1>Sample popup</h1>
<aui:button type="submit" value="Call function" />
<aui:button name="close" value="close" onClick="closeThis();"/>
</form>
Portlet class code:
public class SimplePortlet extends MVCPortlet{
@Override
public void init() throws PortletException {
super.init();
copyRequestParameters = true;
}
public void helloFunction(ActionRequest actionRequest, ActionResponse actionResponse)throws Exception {
System.out.println("Hello!!");
}
}
@Override
public void init() throws PortletException {
super.init();
copyRequestParameters = true;
}
public void helloFunction(ActionRequest actionRequest, ActionResponse actionResponse)throws Exception {
System.out.println("Hello!!");
}
}
