README

@dojo/dom

WARNING This package is deprecated in favor of functionality found elsewhere in Dojo 2. This package is not being further developed at this time as its feature set is redundant with other capabilities.

The @dojo/dom package provides utilities for DOM manipulation and event handling/delegation in browser runtimes. It encourages (and shims) standard DOM methods where possible, but also provides utilities to make common and recommended use cases easy and obvious, and harder use cases less painful.

Features

DOM Manipulation

• dom.applyFeatureClass - accepts any number of feature test names (registered with the has module), and adds corresponding classes to the document element.
• dom.byId - Retrieves an element by ID (shorthand for document.getElementById)
• dom.contains - Determines if an element contains a given node
• dom.create - Creates an element
• dom.fromString - Creates an element or elements from a string of HTML
• dom.remove - Detaches a node from its parent
• dom.place - Places a node relative to another element

CSS Class Manipulation

The class manipulation APIs provide analogues to the DOMTokenList API. They will delegate to classList when available, adding logic when necessary to comply with the more recent parts of the standard (e.g. multiple add/remove arguments, optional force parameter for toggle).

• dom.addClass - Adds one or more classes to an element
• dom.containsClass - Tests if a particular class exists on an element
• dom.removeClass - Removes one or more classes from an element
• dom.toggleClass - Toggles a class on an element, optionally accepting a boolean to specifically add or remove

CSS Style Manipulation

The dom package provides the addCssRule function for adding styles in a stylesheet, rather than inline. This allows styles to be added programmatically on a per-selector basis, which is often more flexible and efficient than setting styles directly inline on one element. When used, addCssRule returns a handle that allows the rules for the provided selector to be manipulated.

The dom package does not provide helpers for setting inline styles, as element.style generally accomplishes that, but moreover, inline styles should be discouraged as they override stylesheets and can be difficult to maintain.

Form Manipulation

These APIs are implemented in a separate dom/form module.

• form.fromObject - Populates a DOM form's fields from a JavaScript object
• form.toObject - Serializes the values in a form into a JavaScript object

DOM Events

The @dojo/core/on module already contains basic support for registering and removing DOM event handlers. The dom package adds APIs for event delegation in the delegate module. The delegate function allows an event handler to be attached to an element in order to respond to events raised by contained elements that match the provided selector.

NOTE: delegate will only respond to events raised by contained elements. It will not respond to events raised by the container itself.

Batch Operations

There are many times when a large number of operations need to be applied to the DOM at one time. In order to enable this to be done as efficiently as possible, the schedule module provides functionality to group the operations together.

• schedule.read - Schedules a function that will retrieve information about the DOM's current state
• schedule.write - Schedules a function that will update the state of the DOM

NOTE: In order to be as flexible as possible, the read and write functions define very generic interfaces. In order to ensure that the operations are executed efficiently, it is important to use these functions only for their intended purpose.

How do I use this package?

Users will need to download and compile directly from this repository and dojo/core for the time being. Precompiled AMD/CommonJS modules will be provided in the near future as our release tools are improved.

Once you've downloaded @dojo/core and @dojo/dom, perform the following steps:

dojo/core
t dist
ist
link
./../@dojo/dom
install # (if you haven't already done this)
link @dojo/core

How do I contribute?

We appreciate your interest! Please see the Guidelines Repository for the Contributing Guidelines and Style Guide.

Testing

Test cases MUST be written using Intern using the Object test interface and Assert assertion interface.

90% branch coverage MUST be provided for all code submitted to this repository, as reported by istanbul?s combined coverage results for all supported platforms.
