Dojo Toolkit is an open source modular JavaScript library (or more specifically JavaScript toolkit) designed to ease the rapid development of cross platform, JavaScript/Ajax based applications and web sites. It was started by Alex Russell, Dylan Schiemann, David Schontzler, and others in 2004 and is dual-licensed under the BSD License and the Academic Free License. The Dojo Foundation is a non-profit organization designed to promote the adoption of the toolkit.


Dojo widgets are prepackaged components of JavaScript code, HTML markup and CSS style declarations that can be used to enrich websites with various interactive features that work across browsers:

  • Menus, tabs, and tooltips
  • Sortable tables, dynamic charts, and 2D vector drawings
  • Animated effects-fades, wipes and slides-facilities for custom animation effects
  • Tree widgets that support drag-and-drop
  • Various forms and routines for validating form input
  • Calendar-based date selector, time selector, and clock
  • Core widgets
