Random Rotating Post Gadget with Excerpt

8:13:00 PM |

Bloggers with plenty of posts in their blogs face a major problem in showing all of them to the viewers. Some solve this by changing the settings to show all the posts in Main Page. This slows down the loading speed of the blog and can turn away visitors.

The Blog Archive gadget which comes as a default with the standard Blogger Layouts shows only the posts in the blog for the present month. The rest of the posts are hidden and can be seen only by clicking the black arrows to expand the archives. This saves the real estate on the blog page but to the new visitor hides the previous months blog posts.

One can eliminate the dates in the Blog Archive and show all your posts in a blogger gadget but this makes a very long sidebar and if you have posts with little content this may make the blog seem lopsided.

To save space and yet show all posts one by one this gadget uses official Google AJAX API Feed technology and the Dynamic Feed Control. It fetches the post titles and data from your blog and displays it in the gadget. To install this on your blog :

  1. Click Add Gadget link in sidebar on Page Elements subtab of Layout tab.
  2. Click Html/Javascript gadget.
  3. Copy the code below and paste after modifying it :

<script src="http://www.google.com/jsapi/?key=PUT_AJAX_KEY_HERE" 
 type="text/javascript"></script>
  <script src="http://www.google.com/uds/solutions/dynamicfeed/gfdynamicfeedcontrol.js" type="text/javascript"></script>

  <script type="text/javascript">

    function showGadget() {
      var feeds = [
       {title:'title',
        url:'http://MYBLOG.blogspot.com/atom.xml?redirect=false&start-index=1&max-results=999'},
       
       ];

      new GFdynamicFeedControl(feeds, 'feedGadget',
                               {numResults : 1000, stacked : true,
                               title: "BLOG_TITLE ~ Random Posts."});
    }
    google.load("feeds", "1");
    google.setOnLoadCallback(showGadget);
  </script>
<div id="feedGadget">Loading...</div>
  <div id="feedGadget">Gadget by <a href="http://www.blogdoctor.me" target="_blank">The Blog Doctor</a>.</div>


In the above code make changes in the following parts :


 <script type="text/javascript">

    function showGadget() {
      var feeds = [
       {title:'title',
        url:'http://MYBLOG.blogspot.com/atom.xml?redirect=false&start-index=1&max-results=999'},
       
       ];

      new GFdynamicFeedControl(feeds, 'feedGadget',
                               {numResults : 1000, stacked : true,
                               title: "BLOG_TITLE ~ Random Posts."});
    }

Change "MYBLOG" to actual blog sub-domain and "BLOG_TITLE" to actual title of your blog. Then paste the modified code in the Html gadget and save the gadget.

Get your AJAX API key and put it in above code instead of 'PUT_AJAX_KEY_HERE'.

Lastly click and drag the HTML gadget from the sidebar to above the posts column. See picture below.



This is because the width of the gadget is more suited for the posts column than the sidebar. Save the Layout. View Blog.
