Blogger Tag Cloud Widget by Categories / Labels

Posted by Musicaholic

This widget is perfect for blogspot users who desire a simple tag cloud for their Categories. The Labels Cloud can easily be implemented within the sidebar of your blog and will match your template wonderfully.
See example below

Example:

Steps for Implementation
Step 1: Back it Up
Always make sure to back up your Template before doing anything else!

Step 2: The Labels Gadget
Make sure that you have the Labels Page Element installed. If you haven't already...

1. Go to Layout >Page Elements .
2. Click "Add a Gadget" and then add the "Labels" gadget.

Step 3: Locating the "Old Code"

1. Now go to Layout >Edit HTML
2. Make sure that the "Expand Widgets Template" box is unchecked.
3. Now we need to search for the code that looks like this.

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

3. Your code may look a little different. So try using your browser's search tool to find type='Label'.

Step 4: Replacing the "Old Code" with the "New Code"

1. Once you've located type='Label', remove the whole line of code that looks just like the code mentioned in part 3 of step 3.
2. Replace this code that you've just deleted with the code below:

</b:if>
<div class='widget-content' style='text-align: justify;'>

//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("<data:label.name/>");
</b:loop>

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

//Counts
var counts = new Array();
<b:loop values='data:labels' var='label'>
counts.push("<data:label.count/>");
</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 != "peek" && x != "forEach" && counts[x] >= minCount)
{
//Calculate textSize
var textSize = min + Math.floor((counts[x]/most) * range);
//Show counts?
if(showCount)
{
var count = "(" + counts[x] + ")";
}else{
var count = "";
}
//Output
document.write("<span style='font-size:" + textSize + "%'><a href='" + urls[x] + "' style='text-decoration:none;'>" + labels[x] + count + "</a></span> " );
}
