1. AJAX Pagination using jQuery in Rails3
Ajax pagination will do the same functionality of pagination without refreshing the page. It call the
action through jQuery to display the results per page. This example demonstrates the
implementation of ajax pagination in Rails3. However the same can be used with Rails2.3.x.
Remember to add jQuery to your paths.
Step#1
Add following gem to your Gemfile
gem 'will_paginate'
Run bundle install
Step#2
Include the following code in the controller you want to paginate, For example, I have used Posts
controller.
class PostsController < ApplicationController
def index
@posts = Post.paginate(page: params[:page], per_page: 10)
end
end
Step#3
Add this in the view “posts/index.html.erb” file
<div id="post_id">
<%= render partial: 'posts' %>
</div>
Encapsulate the order list in the partial view "posts/_posts.html.erb"
<ul>
<% @posts.each do |post| %>
<li>
<!-- Show post data -->
</li>
<% end %>
</ul>
<%= will_paginate(@posts ,:id=>"ajax_paginate") %>
<script>
$(document).ready(function() {
$("#ajax_paginate").find("a").each(function(){

2. var linkElement = $(this);
var paginationURL = linkElement.attr("href");
linkElement.attr({"url": paginationURL,"href": "#"});
linkElement.click(function(){
$("#post_id").html('<div align="center"><br/><img src="/images/loader.gif" /></div>')
$("#post_id").load($(this).attr('url'));
return false;
});
});
});
</script>
The last line "<%= will_paginate(@posts ,:id=>"ajax_paginate") %>" will generate your
pagination links
Voila, You are done!
