<script src="/feeds/posts/summary?alt=json-in-script&callback=showpageCount&max-results=99999" type="text/javascript"></script>
<div style="text-align:right;font-size:10px;color:000000;margin-top:15px;display:none;"> <a href="http://rias-techno-wizard.blogspot.com/2008/07/page-navigation-hack-for-blogger.html">Grab this Widget ~ Blogger Accessories</a></div>

After Adding this Javascript you need to drag and drop the widget below the Blog Posts main widget. See this screen shot

In the code above you can edit the lines in red to your wish .

1 : var pageCount = 5;

The digit in red represents number of posts to be shown in single page. Change the digit to show as many pages you want.

for example :

In my blog I have put that value as 2 . In each page you can see only 2 posts .


2 : var displayPageNum = 3;

here the digit in red represents number of pages to be listed.

For example :

In my blog I have chosen 3 , then 3 pages will be shown.

Now save your template .
That's it now we have added Page Navigation menu widget to our blog successfully .

I hope you guys will feel this method is easier than the last one.

Related Posts Widget For Blogger with CSS

Related Posts Widget for blogger is what everybody is looking for, In Most of the sites we will find only javascript code and HTML tag for related posts widget. After adding the code to your blog , you can see just a list of related posts without any arrows or style css. So i wanted to embed both in order to make the widget links looks beautiful.

First let's see the usual javascript and HTML Tag. Step 1 : Add the following Javascript code below ]]></b:skin> , thats between ]]></b:skin> and </head> .

<script type="'text/javascript'">
//<![CDATA[
var relatedTitles = new Array();
var relatedTitlesNum = 0;
var relatedUrls = new Array();
function related_results_labels(json) {
for (var i = 0; i < json.feed.entry.length; i++) {
var entry = json.feed.entry[i];
relatedTitles[relatedTitlesNum] = entry.title.$t;
for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == 'alternate') {
relatedUrls[relatedTitlesNum] = entry.link[k].href;
relatedTitlesNum++;
break;
}
}
}
}
function removeRelatedDuplicates() {
var tmp = new Array(0);
var tmp2 = new Array(0);
for(var i = 0; i < relatedUrls.length; i++) {
if(!contains(tmp, relatedUrls[i])) {
tmp.length += 1;
tmp[tmp.length - 1] = relatedUrls[i];
tmp2.length += 1;
tmp2[tmp2.length - 1] = relatedTitles[i];
}
}
relatedTitles = tmp2;
relatedUrls = tmp;
}
function contains(a, e) {
for(var j = 0; j < a.length; j++) if (a[j]==e) return true;
return false;
}
function printRelatedLabels() {
var r = Math.floor((relatedTitles.length - 1) * Math.random());
var i = 0;
document.write('<ul>');
while (i < relatedTitles.length &amp;&amp; i < 20) {
document.write('<li><a href="' + relatedUrls[r] + '">' + relatedTitles[r] + '</a></li>');
if (r < relatedTitles.length - 1) {
r++;
} else {
r = 0;
}
i++;
}
document.write('</ul>');
}
//]]>
</script>

Step 2 : Check expand widgets and search for <b:loop values='data:post.labels' var='label'> , Now copy and paste the following code in blue between <b:loop values='data:post.labels' var='label'> and </b:loop>

<b:loop values='data:post.labels' var='label'>
<a expr:href='data:label.url' rel='tag'><data:label.name/></a><b:if cond='data:label.isLast != &quot;true&quot;'>,</b:if><b:if cond='data:blog.pageType == &quot;item&quot;'> <script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=related_results_labels&amp;max-results=5&quot;' type='text/javascript'/> </b:if> </b:loop>

customize the text in green to show as many links you want.

Step 3 : Now paste the following script the code just below <p><data:post.body/></p> .

code :

<script type='text/javascript'> removeRelatedDuplicates(); printRelatedLabels(); </script>

Thats it , now look at the page , it will look like this

You can see there is no styling , I wanted to make it look beautiful . So i made the following changes . Both step 1 and 2 are same , just in step three make some changes .

<div id='related-posts'>
<h2>Other Recommended Posts on This Category</h2>
<script type='text/javascript'> removeRelatedDuplicates(); printRelatedLabels(); </script><
/div>

now its time to add css part for this div section .

/*-- (Related posts widget -below posts) --*/
#related-posts {
float:center;
width:450px;
height:100%;
min-height:100%;
padding-top:5px;
padding-left:5px;
}
#related-posts .widget{
padding-left:6px;
margin-bottom:10px;
background-color:#fff
}
#related-posts .widget h2, #related-posts h2{
font-size: 1.6em;
font-weight: bold;
color: #0000FF;
font-family: Georgia, "Times New Roman", Times, serif;
margin-bottom: 0.75em;
margin-top: 0em;
padding-top: 0em;
}
#related-posts a{
color:#A10000;
}
#related-posts a:hover{
color:#A10000
}
#related-posts ul{
list-style-type:none;
margin:0 0 0px 0;
padding:0px;
text-decoration:bold;
font-size:15px;
text-color:#000000
}
#related-posts ul li{
background:transparent url(http://img152.imageshack.us/img152/3756/bulletzc2.gif) no-repeat ;
display:block;
list-style-type:none;
margin-bottom: 13px;
padding-left: 30px;
padding-top:0px;}

Now look at the page again ,


You can even customize the link color , arrow style , font-size , etc I hope you liked this related posts widget , see you soon with another widget or hack.
