If you’re using Blogger (blogspot), you can see that there is no random posts widget for Blogger blogs. So I make this widget for this purpose. The widget will show a number of posts (which can be modified) in a random order. This is a good way for Blogger users to suggest more content to visitors.
To add random posts widget to Blogger, go to “Dashboard” → “Layout”, click on “Add a gatget” and select type HTML/Javascript. Then paste the following code into the widget content:

- <div id="random-posts"></div>
- <script type='text/javascript'>
- function getRandomPosts(json) {
- var maxEntries = 10;
- var numPosts = json.feed.openSearch$totalResults.$t;
- var indexPosts = new Array();
- for (var i = 0; i < numPosts; ++i) {
- indexPosts[i] = i;
- }
- indexPosts.sort(function() {return 0.5 - Math.random()});
- if (maxEntries > numPosts) {
- maxEntries = numPosts;
- }
- var container = document.getElementById('random-posts');
- var ul = document.createElement('ul');
- for (i = 0; i < maxEntries; ++i) {
- var entry = json.feed.entry[indexPosts[i]];
- var li = document.createElement('li');
- var a = document.createElement('a');
- a.title = entry.title.$t;
- for (var j = 0; j < entry.link.length; ++j) {
- if (entry.link[j].rel == 'alternate') {
- a.href = entry.link[j].href;
- break;
- }
- }
- a.appendChild(document.createTextNode(entry.title.$t));
- li.appendChild(a);
- ul.appendChild(li);
- }
- container.appendChild(ul);
- }
- </script>
- <script src='/feeds/posts/summary?alt=json-in-script&callback=getRandomPosts&max-results=999999' type='text/javascript'></script>
To change the number of random posts will be shown, change the value of
maxEntries in the 4th line (the default value is 10).
- var maxEntries = 10;
After that, save the widget and refresh your blog, you’ll see the random posts right in your blog.
