InputEvent class

Input events are sent as notifications whenever the DOM is being updated.

Inheritance: InputEvent → UIEvent → Event → DOMObject

The InputEvent type exposes the following members:

Constructors

Constructor	Description
init	Initializes a new instance of the `InputEvent` class.

Properties

Property	Description
bubbles	Used to indicate whether or not an event is a bubbling event. If the event can bubble the value is true, else the value is false.
cancelable	Used to indicate whether or not an event can have its default action prevented. If the default action can be prevented the value is true, else the value is false.
current_target	Used to indicate the `IEventTarget` whose `IEventListener`s are currently being processed. This is particularly useful during capturing and bubbling.
event_phase	Used to indicate which phase of event flow is currently being evaluated.
target	Used to indicate the `IEventTarget` to which the event was originally dispatched.
time_stamp	Used to specify the time (in milliseconds relative to the epoch) at which the event was created. Due to the fact that some systems may not provide this information the value of timeStamp may be not available for all events. When not available, a value of 0 will be returned. Examples of epoch time are the time of the system start or 0:0:0 UTC 1st January 1970.
type	The name of the event (case-insensitive). The name must be an XML name.
default_prevented	Returns true if preventDefault() was invoked while the cancelable attribute value is true, and false otherwise.
is_trusted	The isTrusted attribute must return the value it was initialized to. When an event is created the attribute must be initialized to false.
NONE_PHASE	Events not currently dispatched are in this phase.
CAPTURING_PHASE	The event is currently being evaluated at the target `IEventTarget`.
AT_TARGET_PHASE	The current event phase is the capturing phase.
BUBBLING_PHASE	The current event phase is the bubbling phase.
view	The view attribute identifies the Window from which the event was generated. The un-initialized value of this attribute MUST be null.
detail	Specifies some detail information about the Event, depending on the type of event.
data	The data holds the value of the characters generated by an input method. This MAY be a single Unicode character or a non-empty sequence of Unicode characters [Unicode]. Characters SHOULD be normalized as defined by the Unicode normalization form NFC, defined in [UAX15]. This attribute MAY contain the empty string.
is_composing	true if the input event occurs as part of a composition session, i.e., after a compositionstart event and before the corresponding compositionend event. The un-initialized value of this attribute MUST be false.

Methods

Method	Description
get_platform_type	This method is used to retrieve ECMAScript object Type.
init_event	The `Event.init_event` method is used to initialize the value of an `Event` created through the `IDocumentEvent` interface.
prevent_default	If an event is cancelable, the `Event.prevent_default` method is used to signify that the event is to be canceled, meaning any default action normally taken by the implementation as a result of the event will not occur.
stop_propagation	The `Event.stop_propagation` method is used prevent further propagation of an event during event flow.
stop_immediate_propagation	Invoking this method prevents event from reaching any event listeners registered after the current one and when dispatched in a tree also prevents event from reaching any other objects.
