Chapter 12:  Property Inspectors

Example

The following example of the 

displayHelp()

 function opens a file in a browser window. The file 

explains the fields of the Property inspector.

function displayHelp(){

dw.browseDocument(‘http://www.hooha.com/dw/inspectors/inspHelp.html’);

}

inspectSelection()

Description

Refreshes the contents of the text fields based on the attributes of the current selection.

Arguments

maxOrMin

•

The 

maxOrMin

 argument is either 

max

 or 

min

, depending on whether the Property inspector is 

in its expanded or contracted state.

Returns

Dreamweaver expects nothing.

Example

The following example of the 

inspectSelection()

 function gets the value of the 

CONTENT

attribute and uses it to populate a form field called 

keywords

:

function inspectSelection(){

var dom = dreamweaver.getDocumentDOM();

var theObj = dom.getSelectedNode();

document.forms[0].keywords.value = ¬

theObj.getAttribute("content");

}

A simple Property inspector example

The following Property inspector inspects a fictional tag called 

INTJ

. The 

INTJ

 tag is empty (it 

has no closing tag), so its selection type is 

exact

. As long as the selection is an 

INTJ

 tag, the 

Property inspector appears—so the 

canInspectSelection()

 function returns a 

true

 value every 

time. To have a different inspector appear, depending on the value of the 

INTJ

 tag’s 

TYPE

attribute, for example, the 

canInspectSelection()

 function must check the value of the 

TYPE

attribute to determine which Property inspector is the right one. (This is how the keywords and 

description Property inspectors work, because “keywords” and “description” are values, not tags, 

of the 

META

 tag’s 

NAME

 attribute.)
