Two of the Property inspector API functions (canInspectSelection() and inspectSelection()) are required.
canInspectSelection()
Description
Determines whether the Property inspector is appropriate for the current selection.
Arguments
None.
Use dom.getSelectedNode() to get the current selection as a JavaScript object (for more information about dom.getSelectedNode(), see the Dreamweaver API Reference).
Returns
Dreamweaver expects a Boolean value: true if the inspector can inspect the current selection; false otherwise.
Example
The following instance of the canInspectSelection() function returns a true value if the selection contains the CLASSID attribute, and the value of that attribute is "clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" (the class ID for Adobe Flash Player):
function canInspectSelection(){3
var theDOM = dw.getDocumentDOM();
var theObj = theDOM.getSelectedNode();
return (theObj.nodeType == Node.ELEMENT_NODE && ¬
theObj.hasAttribute("classid") && ¬
theObj.getAttribute("classid").toLowerCase()== ¬
"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000");
}
displayHelp()
Description
If this function is defined, a question mark (?) icon appears in the upper-right corner of the Property inspector. This function is called when the user clicks the icon.
Arguments
None.
Returns
Dreamweaver expects nothing.
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");
}
