298 Floating Panels

Example

// the following instance of displayHelp() opens

// in a browser a file that explains how to use

// the extension.

function displayHelp(){

var myHelpFile = dw.getConfigurationPath() +

'/ExtensionsHelp/superDuperHelp.htm';

dw.browseDocument(myHelpFile);

}

documentEdited()

Description

This function is called when the floating panel becomes visible and after the current series of

edits is complete; that is, multiple edits might occur before this function is called. This

function should be defined only if the floating panel must track edits to the document.

Arguments

None.

Returns

Dreamweaver expects nothing.

Example

The following example of the documentEdited() function scans the document for layers and

updates a text field that displays the number of layers in the document:

function documentEdited(){

/* create a list of all the layers in the document */

var theDOM = dw.getDocumentDOM();

var layersInDoc = theDOM.getElementsByTagName("layer");

var layerCount = layersInDoc.length;

/* update the numOfLayers field with the new layer count */

document.theForm.numOfLayers.value = layerCount;

}

NOTE

Define the documentEdited() function only if you require it because its existence

impacts performance.
