The Dreamweaver DOM 73
Properties and methods of text objects
Each contiguous block of text in an HTML document (for example, the text within a
P tag) is
represented by a JavaScript object. Text objects never have children. The following table describes
the properties and methods of text objects that are taken from DOM Level 1 and used in
Dreamweaver. A bullet (•) marks read-only properties.
getElementsByTagName(tagName)
A NodeList that can be used to step through child tags of
type
tagName (for example, IMG, DIV, and so on).
If the
tag argument is LAYER, the function returns all LAYER and
ILAYER tags and all absolutely positioned DIV and SPAN tags.
If the
tag argument is INPUT, the function returns all form
elements. (If a name attribute is specified for one or more
tagName objects, it must begin with a letter, which the HTML
4.01 specification requires, or the length of the array that this
function returns is incorrect.)
hasChildNodes()
A Boolean value that indicates whether the tag has
any children.
hasTranslatedAttributes()
A Boolean value that indicates whether the tag has any
translated attributes. (This property is not included in
DOM Level 1; it was added to Dreamweaver 3 to support
attribute translation.)
