function canAcceptCommand()

{

var PIB = dw.getBrowserList();

if (arguments[0] == 'primary' || arguments[0] == 'secondary')

return havePreviewTarget();

return havePreviewTarget() && (PIB.length > 0);

}

The canAcceptCommand() function in the PIB_Dynamic.js file again retrieves the browser

list that was created in Preferences. Then it checks whether the first argument

(

arguments[0]) is primary or secondary. If so, it returns the value returned by the

havePreviewTarget() function. If not, it tests the call to the havePreviewTarget()

function and tests whether any browsers have been specified (

PIB.length > 0). If both tests

are true, the function returns the value

true. If either or both of the tests are false, the

function returns the value

false.

havePreviewTarget()

The havePreviewTarget() function is a user-defined function that returns the value true

if Dreamweaver has a valid target to display in the browser. A valid target is a document or a

selected group of files in the site panel. The

havePreviewTarget() function looks like the

following example:

function havePreviewTarget()

{

var bHavePreviewTarget = false;

if (dw.getFocus(true) == 'site')

{

if (site.getFocus() == 'remote')

{

bHavePreviewTarget = site.getRemoteSelection().length > 0 &&

site.canBrowseDocument();

}

else if (site.getFocus() != 'none')

{

var selFiles = site.getSelection();

if (selFiles.length > 0)

{

var i;

bHavePreviewTarget = true;

for (i = 0; i < selFiles.length; i++)

{
