Ryan Scherf visited a site which used a drag & drop type download system where you drag an icon over another, then the download immediately starts. He realized this would be easy with the onslaught of the prototype.js and scriptaculous frameworks. Ryan Scherf shows us an example of using the built in Ajax drag & drop for Draggables / Droppables included in scriptaculous to achieve Drag to Download with Ajax.

Timeplot is a DHTML-based AJAXy widget for plotting time series and overlay time-based events over them (with the same data formats that Timeline supports). Just like Timeline or Google Maps, Timeplot can be used with zero software installation, server-side or client-side. You can populate Timeplot with data by pointing it to an space or comma separated file. Timeplot also supports Timeline’s XML format, meaning that you can reuse the same data file of your Timeline and overlay them over a time series plot. It looks so specialized and works smoothly. It is a very great charts tool to represent complex data.

Requirements: Any Browsers supprts Javascript

Sometimes, when we are building websites and web applications, we need a percentage bar / progress bar to show the progress of a specific task. However, it is very difficult to find a working and easy solution without using Flash. Therefore WebAppers has created a simple Javascript based Percentage Bar / Progress Bar which is inspired by Bare Naked App. Bare Naked App taught us how to display Percentage Bar with 2 images only by using CSS. And then I used a little bit of Javascript to make it more interactivity. You can use it anywhere you can think of. Use your Imagination, I am sure you will find it useful somewhere.

Click the image above to see the demo and documentation of Progress / Percentage Bar. And please feel free to grab the package below and test it on your machine.

Download Ajax Progress Bar

Bram.us has created a better version written in objects and unobtrusive, You can view the documentation and demo through Dynamic Unobtrusive Javascript Progress/Percentage Bar.

No one in their right mind likes pop-up windows and personally, the thought of embedding JavaScript blocks within the (X)HTML just doesn’t do it for Brian, so, Brian coded an Unobtrusive Date-Picker that was accessible using the keyboard and suitable for use within documents served as application/xhtml+xml (as no document.write statements are used). The date-picker attempts to auto-detect the language of the users browser installation and download the corresponding language file from the server. And also, it has the nice fade in and fade out effect.

Requirements: Modern Browsers with Javascript Enabled
