Attribute Description Property Type Readonly Description attrChange Number true Indicates the type of change which triggered the DOMAttrModified event. Acceptable values: Value Description MODIFICATION The Attr was modified in place. ADDITION The Attr was just added. REMOVAL The Attr was just removed. attrName String true Indicates the name of the changed Attr node in a DOMAttrModified event. bubbles * Boolean true Used to indicate whether or not an event is a bubbling event. cancelable * Boolean true Used to indicate whether or not an event can have its default action prevented. currentTarget * Node true Used to indicate the EventTarget whose EventListeners are currently being processed. This is particularly useful during capturing and bubbling. defaultPrevented * Boolean true Used to indicate whether preventDefault() has been called for this event. eventPhase * Number true Used to indicate which phase of event flow is currently being evaluated. namespaceURI * String true The namespace URI associated with this event at initialization time, or null if it is unspecified. newValue String true Indicates the new value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharDataModified events. prevValue String true Indicates the previous value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharDataModified events. relatedNode Node true Used to identify a secondary node related to a mutation event. For example, if a mutation event is dispatched to a node indicating that its parent has changed, the relatedNode is the changed parent. If an event is instead dispatched to a subtree indicating a node was changed within it, the relatedNode is the changed node. In the case of the DOMAttrModified event it indicates the Attr node which was modified, added, or removed. target * Node true Used to indicate the EventTarget to which the event was originally dispatched. timeStamp * TimeStamp true Used to specify the time (in milliseconds relative to the epoch) at which the event was created. type * String true The name of the event (case-insensitive). The name must be an XML name. Method Returns Description initEvent * Void The initEvent method is used to initialize the value of an Event created through the DocumentEvent interface. Sytaxis: object.initEvent(type, canBubble, cancelable) Arguments: Name Type O/R Description type String Required Specifies the event type. canBubble Boolean Required Specifies whether or not the event can bubble. cancelable Boolean Required Specifies whether or not the event's default action can be prevented. initMutationEvent Void The initMutationEvent method is used to initialize the value of a MutationEvent object. Sytaxis: object.initMutationEvent(type, canBubble, cancelable, relatedNode, prevValue, newValue, attrName, attrChange) Arguments: Name Type O/R Description type String Required Specifies the event type. canBubble Boolean Required Specifies whether or not the event can bubble. cancelable Boolean Required Specifies whether or not the event's default action can be prevented. relatedNode Node Required Used to identify a secondary node related to a mutation event. prevValue String Required Indicates the previous value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharDataModified events. newValue String Required Indicates the new value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharDataModified events. attrName String Required Indicates the name of the changed Attr node in a DOMAttrModified event. attrChange Number Required Indicates the type of change which triggered the DOMAttrModified event. preventDefault * Void If an event is cancelable, the preventDefault 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. Sytaxis: object.preventDefault() stopImmediatePropagation * Void Prevents other event listeners from being triggered and, unlike stopPropagation() its effect is immediate Sytaxis: object.stopImmediatePropagation() stopPropagation * Void The stopPropagation method is used prevent further propagation of an event during event flow. The event will complete dispatch to all listeners on the current EventTarget before event flow stops. This method may be used during any stage of event flow. Sytaxis: object.stopPropagation() Event B C Interface Description Pseudo-class Description Constant Value Description MODIFICATION 1 The Attr was modified in place. ADDITION 2 The Attr was just added. REMOVAL 3 The Attr was just removed.
