jQuery.Gantt — Draw Gantt charts with the famous jQuery ease of development

Contributors

Marek Bielańczuk wrote the original jQuery.Gantt plugin that this version is based off of.
Tait Brown enforced stricter code guidelines by validating the code, updating it to support HTML5 and tweaking the design.
Leo Pfeifenberger made major performance updates as well as adding requested features such as click events, state persisting via cookies and scrollToToday on load functionality.
Grzegorz Russek helped fix the White Whale of a bug that prevented the hour view rendering correctly. Nice one.

Gantt Configuration

$(".selector").gantt({
    source: "ajax/data.json",
    scale: "weeks",
    minScale: "weeks",
    maxScale: "months",
    onItemClick: function(data) {
        alert("Item clicked - show some details");
    },
    onAddClick: function(dt, rowId) {
        alert("Empty space clicked - add an item!");
    },
    onRender: function() {
        console.log("chart rendered");
    }
});

Parameter	Default	Accepts Type
`source`	`[]`	Array, string (url)
`itemsPerPage`	`7`	number
`months`	`["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]`	Array (12 strings representing the months of the year)
`dow`	`["S", "M", "T", "W", "T", "F", "S"]`	Array (7 strings representing the days of the week)
`holidays`	`undefined`	Array of numbers (ms), date strings (see formats), or Date objects
`navigate`	`"buttons"`	string ("buttons", "scroll")
`scale`	`"days"`	string ("months", "weeks", "days", "hours")
`maxScale`	`"months"`	string ("months", "weeks", "days", "hours")
`minScale`	`"hours"`	string ("months", "weeks", "days", "hours")
`waitText`	`"Please wait..."`	string
`onItemClick`	`function (data) { return; }`	Function called when clicking on a Gantt item. The parameter passed to the function is the dataObj of the source item, if one was provided.
`onAddClick`	`function (dt, rowId) { return; }`	Function called when clicking on empty space inside the Gantt data panel. The parameter passed to the function is the date/time in milliseconds for the clicked cell, and the ID of the source object (row), if one was provided.
`onRender`	`$.noop`	Function called whenever the chart is (re)rendered
`useCookie`	`false`	indicates whether or not cookies should be used to save and restore the chart's view state (scale, scroll position) between page loads; `jquery.cookie` needs to be referenced for this to work
`cookieKey`	`"jquery.fn.gantt"`	The prefix used when storing cookies (depends on useCookie being set to `true`)
`scrollToToday`	`true`	Boolean
