the handler function, null if the property is null or not a function

jsxFunction_addEventListener

public void jsxFunction_addEventListener(java.lang.String type,
                                         org.mozilla.javascript.Function listener,
                                         boolean useCapture)

Allows the registration of event listeners on the event target.

Parameters:

type - the event type to listen for (like "click")

listener - the event listener

useCapture - If true, indicates that the user wishes to initiate capture

See Also:

Mozilla documentation

jsxFunction_appendChild

public java.lang.Object jsxFunction_appendChild(java.lang.Object childObject)

Add a DOM node to the node

Parameters:

childObject - The node to add to this node

Returns:

The newly added child node.

jsxFunction_attachEvent

public boolean jsxFunction_attachEvent(java.lang.String type,
                                       org.mozilla.javascript.Function listener)

Allows the registration of event listeners on the event target.

Parameters:

type - the event type to listen for (like "onclick")

listener - the event listener

Returns:

true if the listener has been added

See Also:

MSDN documentation

jsxFunction_cloneNode

public java.lang.Object jsxFunction_cloneNode(boolean deep)

Duplicate an XML node

Parameters:

deep - If true, recursively clone all descendants. Otherwise, just clone this node.

Returns:

The newly cloned node.

jsxFunction_detachEvent

public void jsxFunction_detachEvent(java.lang.String type,
                                    org.mozilla.javascript.Function listener)

Allows the removal of event listeners on the event target.

Parameters:

type - the event type to listen for (like "onclick")

listener - the event listener

See Also:

MSDN documentation

jsxFunction_hasChildNodes

public boolean jsxFunction_hasChildNodes()

Returns whether this node has any children.

Returns:

boolean true if this node has any children, false otherwise.

jsxFunction_insertBefore

public java.lang.Object jsxFunction_insertBefore(java.lang.Object newChildObject,
                                                 java.lang.Object refChildObject)

Add a DOM node as a child to this node before the referenced node. If the referenced node is null, append to the end.

Parameters:

newChildObject - The node to add to this node

refChildObject - The node before which to add the new child

Returns:

The newly added child node.

jsxFunction_isSameNode

public boolean jsxFunction_isSameNode(java.lang.Object other)

This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.

Parameters:

other - The node to test against.

Returns:

whether this node is the same node as the given one.

jsxFunction_removeChild

public java.lang.Object jsxFunction_removeChild(java.lang.Object childObject)

Remove a DOM node from this node

Parameters:

childObject - The node to remove from this node

Returns:

The removed child node.

jsxFunction_removeEventListener

public void jsxFunction_removeEventListener(java.lang.String type,
                                            org.mozilla.javascript.Function listener,
                                            boolean useCapture)

Allows the removal of event listeners on the event target.

Parameters:

type - the event type to listen for (like "click")

listener - the event listener

useCapture - If true, indicates that the user wishes to initiate capture (not yet implemented)

Returns:

The removed child node.
