Instance Method Details

- (Object) ajax_pagination(format, options = {})

Registers a javascript format when params matches options ( = "page" by default). AJAX Pagination uses this response to render only the content which has changed. When this format is triggered, a partial is passed back, and sent to AJAX Pagination as a function argument in javascript.

Call this method in a respond_to block, in a controller action:

class CommentsController < ApplicationController
  def index
    @comments = Comment.all
    respond_to do |format|
      format.html # index.html.erb
      ajax_pagination(format)
    end
  end
end

Options:

:pagination

Changes the pagination name triggering this response. Triggered when params&#91;:pagination&#93; == options&#91;:pagination&#93;. Defaults to "page"

:partial

Changes the partial that is returned by this response. Defaults to options&#91;:pagination&#93;.
