+// infinite_scroll.js displays a tab's content using automatic scrolling
+// when the user scrolls to the bottom of the page and there is more data.
+//
+// Usage:
+//
+// 1. Adding infinite scrolling to a tab pane using "show" method
+//
+// The steps below describe adding scrolling to the project#show action.
+//
+// a. In the "app/views/projects/" folder add a file for your tab
+// (ex: _show_jobs_and_pipelines.html.erb)
+// In this file, add a div or tbody with data-infinite-scroller.
+// Note: This page uses _show_tab_contents.html.erb so that
+// several tabs can reuse this implementation.
+// Also add the filters to be used for loading the tab content.
+//
+// b. Add a file named "_show_contents_rows.html.erb" that loads
+// the data (by invoking get_objects_and_names from the controller).
+//
+// c. In the "app/controllers/projects_controller.rb,
+// Update the show method to add a block for "params[:partial]"
+// that loads the show_contents_rows partial.
+// Optionally, add a "tab_counts" method that loads the total number
+// of objects count to be displayed for this tab.
+//
+// 2. Adding infinite scrolling to the "Recent" tab in "index" page
+// The steps below describe adding scrolling to the pipeline_instances index page.
+//
+// a. In the "app/views/pipeline_instances/_show_recent.html.erb/" file
+// add a div or tbody with data-infinite-scroller.
+//
+// b. Add the partial "_show_recent_rows.html.erb" that displays the
+// page contents on scroll using the @objects

// infiniteContentParamsFilterable ("search for text foo")
// without worrying about clobbering the filters set up by the
- // tab pane ("only show jobs and pipelines in this tab").
+ // tab pane ("only show container requests and pipeline instances
+ // in this tab").
