Generate a "tag cloud" using DynaCloud (jQuery Plugin)

To make your application look more Web 2.0, it's a good idea to add a Tag Cloud section on some pages. ;)
I did a little search for a jQuery plugin that can do the job and I found DynaCloud.

You can include a Tag Cloud on your page in 4 steps.

1) Add on your page a container for the tag cloud. For good results create an HTML Region and put the following code in the region source. (Set the template to Sidebar Region)

<div id="dynacloud" style="font-size:12px;"></div>


2) Load jQuery using Google AJAX Libraries API

<script src="http://www.google.com/jsapi"></script>
<script>
// Load jQuery
google.load("jquery", "1.2.6", {uncompressed:false});
</script>


3) Load DynaCloud Plugin

<script src="&WORKSPACE_IMAGES.jquery.dynacloud-4.js"></script>


4) Add CSS styles to display the Tag Cloud

<style type="text/css">
div#dynacloud {
font-size:5px;
}
div#dynacloud a span{
font-size:1em;
}
.highlight { background-color: yellow }
</style>


5) Configure the settings of DynaCloud. When the page his loaded, add the CSS class "dynacloud" to your page reports regions. And finally, generate the tag cloud.

<script>
$.dynaCloud.sort = false;

$().ready(function() {
$('.t4ReportsRegion').addClass("dynacloud");
$('.dynacloud').dynaCloud();
});
</script>



You can see my working example of a Tag Cloud in APEX.


Talking about clouds, here in Montreal it's snowing... they announced 15-30cm of snow for today. Tonight traveling back home will be long! ;)

Followed everything. Tag cloud displays but not with text in varying sizes. Have I missed a step or a switch I need to set in the javascript?

Marco,

You probably have a problem with the CSS.

Don't forget to define the CSS for the tag cloud.

<style type="text/css">
div#dynacloud {
font-size:5px;
}
div#dynacloud a span{
font-size:1em;
}
.highlight { background-color: yellow }
</style>

Let me know if it works or not.

Hi,

I'm trying to use this plugin on an application, but simply cannot make it work. Can you take a look to see if you can figure out what I'm doing wrong?

Let me tell you this is my first ver attempt to use a jQuery plugin.

Please help! This is a university project and I really don't know what else to do...
