JavaScript Programmer’s Reference Warnings: . No longer supported in Netscape 6.0. See also: Hierarchy of objects, Layer object, Layer.siblingBelow Property attributes: ReadOnly. Layer.siblingBelow (Property) A layer that is related to this layer and below it in the Z ordering. JavaScript 1.2 Netscape 4.0 Deprecated Availability: Property/method value type: JavaScript syntax: N Warnings: .No longer supported in Netscape 6.0. Layer object myLayer.siblingBelow See also: Layer object, Layer.siblingAbove Property attributes: ReadOnly. Layer.src (Property) The source URL for a layer. JavaScript 1.2 Netscape 4.0 Deprecated Availability: Property/method value type: JavaScript syntax: N String primitive myLayer.src Changing this layer property value forces the browser to load a new document into the layer. This can work very effectively if you generate dynamic content via a javascript: URL as the value assigned to the src property. 1314

L Layer.siblingAbove (Property) Any layers sharing a common parent layer will all be present in the same layers[] collection. They are considered to be siblings and can be ordered with respect to one another. They are ordered collectively by their parent’s relationship with its siblings and you cannot interleave siblings from different sets with one another; the set as a whole must be ordered within its parent’s z-axis location. Parent/Child Siblings Siblings sibling above sibling above sibling above 1313

JavaScript Programmer’s Reference Object 1 Object 2 Object 3 Object 4 Warnings: . No longer supported in Netscape 6.0. See also: Layer.handleEvent(), Window.routeEvent() Layer.siblingAbove (Property) A layer that is related to this layer and above it in the Z ordering. JavaScript 1.2 Netscape 4.0 Deprecated Availability: Property/method value type: JavaScript syntax: N Layer object myLayer.siblingAbove Given that a layer arrangement is yet another example of a tree structured hierarchy within a page, this property yields the next higher sibling belonging to the same parent (or null if this is the highest element). 1312

L Layer.resizeTo() (Method) Layer.resizeTo() (Method) Adjusts the size of a layer to an absolute value. JavaScript 1.2 Netscape 4.0 Deprecated Availability: JavaScript syntax: N anX An X axis value Argument list: aY myLayer.resizeTo(anX, aY) A Y axis value This method provides a way to set the absolute size of a layer as opposed to the relative sizing offered by the resizeBy() method. Although the size changes, the top left corner will remain pinned to its current location growing or shrinking the layer to the right and bottom of its extent. Warnings: . No longer supported in Netscape 6.0. See also: Layer.resizeBy() Layer.routeEvent() (Function) Part of the Netscape event propagation complex. Availability: JavaScript 1.2 Netscape 4.0 Deprecated Property/method value type: undefined JavaScript syntax: N myLayer.routeEvent(anEvent) Argument list: An event object anEvent 1311

JavaScript Programmer’s Reference Layer.resizeBy() (Method) Adjusts the size of a layer by a relative amount. JavaScript 1.2 Netscape 4.0 Deprecated Availability: JavaScript syntax: N anX A relative distance in the X axis Argument list: aY The layer can have its size adjusted by a value measured in pixels. This can apply to the horizontal or vertical axis or both if necessary. The value can be positive or negative causing the layer to grow or shrink respectively. Although the size changes, the top left corner will remain pinned to its current location growing or shrinking the layer to the right and bottom of its extent. myLayer.resizeBy(anX, aY) A relative distance in the Y axis Delta X Delta Y Warnings: . No longer supported in Netscape 6.0. See also: Layer.resizeTo() 1310

L Layer.releaseEvents() (Function) Warnings: . No longer supported in Netscape 6.0. See also: Layer.moveTo() Property attributes: ReadOnly. Layer.releaseEvents() (Function) Part of the Netscape 4 event propagation complex. JavaScript 1.2 Netscape 4.0 Deprecated Availability: Property/method value type: undefined JavaScript syntax: myLayer.releaseEvents(anEventMask) N anEventMask A mask defined with the manifest event Argument list: constants This is part of the event management suite which allows events to be routed to handlers other than just the one that defaults to being associated with an event. The events to be captured are signified by setting bits in a mask. This method provides a means of indicating which events are no longer needing to be captured by the receiving Layer object. The events are specified by using the bitwise OR operator (|) to combine the required event mask constants into a mask that defines the events you want to capture. Refer to the Event Type Constants topic for a list of the event mask values. Since this is only supported by Netscape, the functionality is likely to be deprecated when the standards bodies agree on a standard way of handling events. In the meantime, we shall have to implement scripts using this capability if we need to build complex event handling systems. A different script will be required for MSIE. You may be able to factor your event handler so that you only have to make platform specific event dispatchers, and can call common handling routines that can be shared between MSIE and Netscape.

JavaScript Programmer’s Reference Layer.pageY (Property) The Y-coordinate of the layer relative to the top level document. Availability: JavaScript 1.2 Netscape 4.0 Deprecated Property/method value type: Number primitive JavaScript syntax: N myLayer.pageY Offset X Window Layer 1 Layer 2 Offset Y Warnings: . No longer supported in Netscape 6.0. See also: Layer.moveToAbsolute() Layer.parentLayer (Property) The layer containing the current layer (for a single layer, this is the window object). JavaScript 1.2 Netscape 4.0 Deprecated Availability: Property/method value type: JavaScript syntax: N Layer or Window object myLayer.parentLayer 1308
