Very Simple Blogger Tag Cloud Widget for your Blog

Friday, September 17, 2010

Searching for tag cloud widget for your blog ? well they are so many up there on the net ! but since many people want and search for easy way ! so here is the easy GUM GUM :)
Actually this hack brought to you by Raymond which was the most simple blogger tag cloud i ever found until now !
How to apply:
============
Installation:

If you already have a Labels page element installed, skip to step 2.

Step 1: Install the Labels page element by browsing to your template settings:



Click "Add a Page Element" in the column you wish:



Then find the Labels page element and click "Add to Blog":



Step 2: Replace the Labels page element widget code with the custom tag cloud code above.

First navigate to your templates source under your template settings:



Then check off "Expand Widget Templates":



Search for the Label page element you are replacing by searching for widget code. It will look something like this

<b:widget id='Label1' locked='false' title='Tags' type='Label'>

but id and title maybe different, so use your browser's search tool and look for type='Label'.

Delete the Label widget code from the start to the end marked by

</b:widget>

and replace with the custom Tag Cloud code from above.

<b:widget id='Label1' locked='false' title='Tags' type='Label'>
<b:includable id='main'>
<b:if cond='data:title'>
<h2><data:title/></h2>
</b:if>
<div class='widget-content' style='text-align: justify;'>
<script type='text/javascript'>

//Settings / Variables
var max = 150; //max css size (in percent)
var min = 70; //min css size (in percent)
var showCount = false;  // show counts? true for yes, false for no
var minCount = 1;  // what is the minimum count for a tag to be shown? 1 for all


//Begin code:
var range = max - min;

//Build label Array
var labels = new Array();
<b:loop values='data:labels' var='label'>
labels.push(&quot;<data:label.name/>&quot;);
</b:loop>

//URLs
var urls = new Array();
<b:loop values='data:labels' var='label'>
urls.push(&quot;<data:label.url/>&quot;);
</b:loop>

//Counts
var counts = new Array();
<b:loop values='data:labels' var='label'>
counts.push(&quot;<data:label.count/>&quot;);
</b:loop>

//Number sort funtion (high to low)
function sortNumber(a, b)
{
return b - a;
}

//Make an independant copy of counts for sorting
var sorted = counts.slice();

//Find the largest tag count
var most = sorted.sort(sortNumber)[0];

//Begin HTML output
for (x in labels)
{
if(x != &quot;peek&quot; &amp;&amp; x != &quot;forEach&quot; &amp;&amp; counts[x] >= minCount)
{
//Calculate textSize
var textSize = min + Math.floor((counts[x]/most) * range);
//Show counts?
if(showCount)
{
var count = &quot;(&quot; + counts[x] + &quot;)&quot;;
}else{
var count = &quot;&quot;;
}
//Output
document.write(&quot;<span style='font-size:&quot; + textSize + &quot;%'><a href='&quot; + urls[x] + &quot;' style='text-decoration:none;'>&quot; + labels[x] + count + &quot;</a></span> &quot; );
}
}
