3. jQuery GanttView


The jQuery.ganttView plugin is a very lightweight plugin for creating a Gantt chart in plain HTML, no vector graphics or images required. The plugin supports dragging and resizing the Gantt blocks and callbacks to trap the updated data.

The plugin depends on the following libraries:

  • jQuery 1.4 or higher (obviously)
  • jQuery-UI 1.8 or higher
  • date.js

Currently the plugin has been tested, and is working in: FF 3.5+, Chrome 5+, Safari 4+, IE8+. There are minor issues in IE7 and I haven't even attempted to use it in IE6. If you encounter any issues with any version of Internet Explorer and would like to contribute CSS fixes please visit the repository and create pull requests, several people have asked for IE6 support.

2. TW Gantt

Github | Documentation

Originally, Twproject Gantt editor is a free online tool for creating and sharing Gantts, however they provide its Gantt component written in JavaScript and built on jQuery for creating Gantts, task trees, dependencies which exports the resulting data in JSON format.

  • in-place editing.
  • drag & drop.
  • zooming.
  • do/undo.
  • multiple dependencies.
  • critical path.
  • full editing.
  • dates.
  • shortcuts.
  • css skin.
  • milestones.
  • multiple browser.
  • resources editing.
  • multiple assignments.
  • export data in JSON format resize & scroll SVG smooth drawing print friendly.

While a Gantt viewer (hence read-only) can be easily packed as a single component, a Gantt editor is a way more complicated object, therefore the authors prefer to think of it as an embedded jQuery application and not just as a plugin.
