The tag editor should appear.

Tag editor APIs

In order to create a new tag editor, you must provide an implementation for the

inspectTag(), validateTag(), and applyTag() functions. For an example of an

implementation, see “Creating a tag editor UI” on page 272.

inspectTag()

Availability

Dreamweaver MX.

Description

The function is called when the tag editor first appears. The function receives as an argument

the tag that the user is editing, which is expressed as a

dom object. The function extracts

attribute values from the tag that is being edited and uses these values to initialize form

elements in the tag editor.

Arguments

tag

■ The tag argument is the DOM node of the edited tag.

Returns

Dreamweaver expects nothing.

Example

Suppose the user edits the following tag:

If the editor contains a text field for editing the zip attribute, the function needs to initialize

the form element so that the user sees the actual ZIP code in the text field, rather than an

empty field.

The following code performs the initialization:

function inspectTag(tag)

{

document.forms[0].zip.value = tag.zip

}
