Carousel portlet

[Kristian Gil, modificado hace 12 años.]

Hi,

We're planning on implementing a Carousel portlet like the one at Yahoo's home page.
Does anyone have a suggestion if there is already an existing portlet for this or if it's better to develop one from scratch?
One idea we had was to create another view for the Asset Publisher portlet using JQuery or maybe AlloyUI.
We're running on Liferay 5.1.7.

Any suggestion is appreciated, thanks!

I did that using the Jquery jcarousel plugin. This plugin needs the elements to move to be list items inside an unordered list, so I had to wrap the HTML that the asset publisher produced in li tags inside journal/asset/abstract.jsp and print ul tags inside asset_publisher/display/abstracts.jsp. Those JSPs need to be deployed inside a hook plugin.

Hope this helps

The simplest way:

<script type="text/javascript" charset="utf-8">
AUI().ready('aui-carousel', function(A) {

	var component = new A.Carousel(
		{
			intervalTime: 5,
			contentBox: '#divanim',
			activeIndex: 'rand',
			height: 28,
			width: 780
		}
	)
	.render();

});
</script>

You can use webcontent :

structure :

<root>
  <dynamic-element name="duration" type="list" index-type="" repeatable="false">
  <meta-data>
			<entry name="displayAsTooltip">false</entry>
			<entry name="required">false</entry>
			<entry name="instructions">Select how long, in seconds, you would prefer to display an item before switching to the next slide</entry>
			<entry name="label">Item Duration</entry>
			<entry name="predefinedValue"></entry>
		</meta-data>

    <dynamic-element name="1" type="1" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="2" type="2" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="3" type="3" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="4" type="4" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="5" type="5" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="6" type="6" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="7" type="7" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="8" type="8" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="9" type="9" index-type="" repeatable="false">  </dynamic-element>
    <dynamic-element name="10" type="10" index-type="" repeatable="false"></dynamic-element>
  </dynamic-element>
  <dynamic-element name="height" type="text" index-type="" repeatable="false">
  <meta-data>
			<entry name="displayAsTooltip">false</entry>
			<entry name="required">true</entry>
			<entry name="instructions">This defines the height of the carousel, in pixels(px). Do not add "px" at the end of the value</entry>
			<entry name="label">Height</entry>
			<entry name="predefinedValue"></entry>
		</meta-data>
</dynamic-element>
  <dynamic-element name="width" type="text" index-type="" repeatable="false">
  <meta-data>
			<entry name="displayAsTooltip">false</entry>
			<entry name="required">true</entry>
			<entry name="instructions">This defines the width of the carousel, in pixels(px). Do not add "px" at the end of the value</entry>
			<entry name="label">Width</entry>
			<entry name="predefinedValue"></entry>
		</meta-data>
</dynamic-element>
  <dynamic-element name="content" type="text_area" index-type="text" repeatable="true">
  <meta-data>
			<entry name="displayAsTooltip">false</entry>
			<entry name="required">true</entry>
			<entry name="instructions">This is the content of this slide. To create more slides, click on the " " button</entry>
			<entry name="label">content</entry>
			<entry name="predefinedValue"></entry>
		</meta-data>
</dynamic-element>
</root>

Template

#set ($contentId = $reserved-article-id.getData())
#set ($contentClass = "multiple-items-" + $contentId + "-carousel")

<style type="text/css" media="screen">
	#$contentClass {
		height: $height.getData()px;
		position: relative;
		width: $width.getData()px;
	}

	#$contentClass .carousel-item {
		height: $height.getData()px;
		overflow: hidden;
		width: $width.getData()px;
		position: absolute;
		top: 0;
	}
</style>

<div id="$contentClass">
	#foreach ($item in $content.getSiblings())
		<div class="carousel-item">
			$item.getData()
		</div>
	#end
</div>

<script type="text/javascript">
	AUI().ready(
	'aui-carousel',
	function(A) {
		var component = new A.Carousel(
			{
				activeIndex: 'rand',
				contentBox: '#$contentClass',
				height: $height.getData(),
				intervalTime: $duration.getData(),
				width: $width.getData()
			}
		)
		.render();
	});
</script>

I tried using the Alloy UI and could successfully achieve it. But the problem what I faced was that every time my portal page use to get refreshed, the Carousel use to get reloaded. And whenever the Carousel gets reloaded, it displays all the <div>'s for few seconds and then starts its carousel effect. I want to avoid this. Is there any way I can configure this?

Thanks and Regards,
Nilesh.

Hi Nilesh,

I don't think you can avoid this "feature". It all depends on your network connection speed because the page has to be completely loaded before the carousel script is run. So all html has to be loaded before the js effect can start and redisplay the carousel contents. Testing it at localhost you shouldn't see the divs.

Hi Oliver,

Many Thanks for your reply. But I dont see this to be a network connection speed problem. As I am not facing the same problem when I am surfing the liferay.com. As we know in liferay.com, on its home page itself, Alloy Carousel is used where different images are embedded inside the div are is carousel effect.

But while surfing this, I am not facing any problem. There is no reloading delay which makes all the content to be seen first, and then effect.

I am facing problem in my local system itself. I will post my code here.

Regards,
Nilesh.

I dont want to have all the information in the same web content... I like to do the same but web content with a special tag or categories

Just thought I'd let everyone know that I recently made a photo carousel portlet that uses Alloy UI carousel which you can quite conveniently configure and it pulls the images from Document's and Media.

[Matus Ferko, modificado hace 11 años.]

Mika I am not able to build the portlet with build-css goal enabled

<executions>
		<execution>
			<phase>generate-sources</phase>
				<goals>
					<goal>build-css</goal>
				</goals>
		</execution>
	</executions>

Edit 1:
I use plugin version 6.1.1
I receive error

Failed to execute goal com.liferay.maven.plugins:liferay-maven-plugin:6.1.1:build-css (default) on project photo-carousel-portlet: basedir C:\...\photo-carousel-portlet\target\photo-carousel-portlet-0.1-SNAPSHOT does not exist. -> [Help 1]

[Mika Koivisto, modificado hace 11 años.]

It requires 6.1.1 or 6.1.20 version of the Liferay maven plugin which has the build-css goal.

Hello Mika,

i tried your photo portlet. It have everything on board i need, thank you very much.
But could it be, that if you enable link and store url per picture, that this works ( mouse / hyperlink ) in FF but not in IE 8 ?

Caused by: org.apache.jasper.JasperException: An exception occurred processing JSP page /view.jsp at line 29
thanks

In Liferay 5.1.7 there is no Alloy UI, is it? I think the way to go is with Jquery.
