YUI Library: Index of Official Examples

Every YUI Library component ships with a series of 315 examples that illustrate its implementation. These examples can serve as starting points for your exploration of YUI, as code snippets to get you started in your own programming, or simply as an inspiration as to how various interaction patterns can be enabled in the web browser via YUI.

The navigation controls on the left side of this page allow you to explore these examples component-by-component; on this page you'll find the full index of library examples with a link to and short description of each one.

Inline Editing of TreeView Node Labels	TreeView has intrinsic support for user-editing of node labels. This example explores the interaction model for inline editing with TreeView. It also illustrates the use of a special date-editor class that leverages the YUI Calendar Control.

Uploader Control (beta)
Simple Uploader Example With Button UI	A demonstration of core features of the Uploader Control. In this example, the Uploader control is rendered as a sprite-skinned button. The user is allowed to select a single file and upload it to a specified location. The upload progress is tracked and reported back to the user.
Advanced Uploader Example With Additional POST Variables and Server Data Return	This advanced Uploader example is rendered as a transparent overlay UI over a text link. It allows the user to upload a single file, along with additional POST variables, and displays the data returned back from the server.
Advanced Uploader Example With Cookie Submission as a POST variable	This advanced Uploader example demonstrates setting of a document cookie and attaching the cookie data as a variable in the file upload POST request. The backend server echoes the submitted data, ascertaining that the cookie data has been received.
Advanced Uploader Example With Transparent UI and Automatic Queue Management	This advanced Uploader example is rendered as a transparent overlay UI over a text link. The uploader allows the user to upload multiple files, using built-in queue management, and reports back progress.

ProfilerViewer Control
Simple Profiling	A simple use case profiling a Calendar Control instance with the ProfilerViewer Control.
Using the ProfilerViewer API while Profiling the YUI Menu Control	In this example, profiling a simple set of menus and submenus, ProfilerViewer's API is leveraged to place the console in a floating, draggable palette.
Using Profiler and ProfilerViewer to Profile non-YUI Code	This example explores the best strategy for using YUI to profile projects that are not YUI-based; it shows you how to load only the minimal YUI footprint during profiling, deferring the loading of ProfilerViewer (and its YUI dependencies) until you're ready to view the profiling data.
Skinning the ProfilerViewer Control	ProfilerViewer's 'skin' is provided via a combination of CSS and other style information passed via JavaScript to the Flash-based Charts Control. This example helps you understand where to start if you want to customize the look and feel of a ProfilerViewer implementation.
ProfilerViewer Internationalization: Spanish	The ProfilerViewer Control can be easily internationalized by modifying the STRINGS member of YAHOO.widget.ProfilerViewer In this example, a Spanish translation provided by Caridy Patiño Mayea is applied to the UI.
ProfilerViewer Internationalization: German	The ProfilerViewer Control can be easily internationalized by modifying the STRINGS member of YAHOO.widget.ProfilerViewer In this example, a German translation provided by Christian Heilmann is applied to the UI.
