The function should return a new item that will be inserted into the calendar. If a return

without data is executed, no new entry will be added.

The widget also has some very useful functions available upon it:

• floorDate()

• floorToDay()

The widget also responds to events:

• onItemContextMenu – Invoked when a context menu is request. Passed in object

contains:

◦ item – The item that was chosen.

◦ source – The object that is the source of the selection.

◦ triggerEvent – The event that caused the menu to be shown.

Parsing Dijit in HTML

Within an HTML page we can insert markers in the source of the HTML that will be parsed when

Dojo is loaded. These markers will be used to dynamically create instances of Dijit widgets. The

purpose of this technique is to allow us to declaratively build web pages that use the Dijit widgets

without having to explicitly code those up in JavaScript.

Dijit widgets can be created automatically in pages by flagging HTML elements with an indication

of the type of Dijit widget to be created. The type is flagged using the "data-dojo-type"

attribute:

data-dojo-type="<Widget Type>"

The Widget Type is a package name such as "dijit/form/Button".

Properties of the widget can also be supplied with:

data-dojo-props="<properties>"

The format of these properties is "name: value, name: value ..."

A global variable can be created and will be assigned as a reference to the newly created widget

using the following syntax:

data-dojo-id="<variableName>"

We need to be careful if we are defining modules and those modules have an expectation that all

parsing has been completed before having their core functions executed.

In the definition of such modules, code the following:

require(["dojo/ready", …], function(ready, …) {

ready(function() {

// Code here will be run after initializations.

}

});

When using the parser, we typically include markup that looks as follows:

</div>
