JavaScript 2.0-The Complete Reference, Second ... - freecodingtutorial

setExpression(property, expression [, language]) Sets the expression given in
string expression as the dynamic expression for the property given in string property.
The optional language parameter specifies which scripting language the expression is
written in, for example, "VBscript" (JScript is the default). Commonly used as a method
of element nodes and Style objects. Used for setting dynamic expressions. (IE5+)
swapNode(node) Exchanges the location of the object with node in the object
hierarchy. (IE5+)
unwatch(property) Removes the watchpoint on the property given in the string
property. (N4+)
watch(property, handler) ―Watches‖ the property given in string property and invokes
the function handler whenever its value changes. The handler is passed the name of
the property, the old value, and the value to which it is being set. Any value the function
returns is interpreted as the new value for the property. (N4+)
Notes
With the exception of the object scriptable under traditional models (Form, Image, and
so on), most elements become scriptable in Internet Explorer 4+, Mozilla/Netscape 6+,
and DOM1.
HTML elements are referred to both in uppercase and lowercase under the DOM, so
and are both equivalent to an HTMLParagraph object.
a, Anchor, Link, HTMLAnchorElement (Document Object)
In traditional models, there was a separate object for an tag that specified a name attribute
(called an Anchor) and one that specified an href attribute (called a Link). This nomenclature
is outdated, and with the rise of the DOM there is no distinction. Modern browsers typically
mesh Anchor and Link into a more appropriate object, which corresponds to any element
on the page, and fill in the Anchor- or Link-related properties if they are defined. In the
following list, we note explicitly those properties and methods that are available only in Anchor
or Link in traditional object models.
Access to these objects is achieved through standard DOM methods like
document.getElementById(). However, you can also access those elements with name
attribute set through the anchors[] collection of the Document, and those elements with href
attribute through the links[] collection.
Properties
This object has the following properties in addition to those in the Generic HTML Element
object listed at the beginning of this appendix:
accessKey Single character string indicating the hotkey that gives the element focus.
(IE4+, MOZ/N6+, DOM1)
charset String indicating the character set of the linked document. (IE6+, MOZ/N6+,
DOM1)
coords String (comma-separated list) defining the coordinates of the object, used with
the shape attribute. However, there is no default functionality. (IE6+, MOZ/N6+, DOM1)
dataFld String specifying which field of a data source is bound to the element. (IE4+)
dataFormatAsv String indicating how the element treats data supplied to it. (IE4+)
dataSrc String containing the source of data for data binding. (IE4+)
disabled Boolean indicating whether the element is disabled (grayed out). (IE4+)
hash String holding the portion of the URL in the href following the hash mark (#).
Defined for Link in traditional models. (IE3+, N2+, MOZ)
host String holding the domain name and port portion of the URL in the href. Defined
for Link in traditional models. (IE3+, N2+, MOZ)
hostname String holding the domain name portion of the URL in the href. Defined for
Link in traditional models. (IE3+, N2+, MOZ)
href String holding the value of the href attribute, the document to load when the link is
activated. Defined for Link in traditional models. (IE3+, N2+, MOZ, DOM1)
hreflang String indicating the language code of the linked resource. (MOZ/N6+, IE6+,
DOM1)
media String indicating the media of the link. Currently unsupported. (DOM1)
