if (whichBrowser == 'primary')

{

result = window.confirm(MSG_NoPrimaryBrowserDefined);

}

else if (whichBrowser == 'secondary')

{

result = window.confirm(MSG_NoSecondaryBrowserDefined);

}

// If the user clicked OK, show the prefs dialog with the browser

panel.

if (result)

dw.showPreferencesDialog('browsers');

}

The function first sets the variable whichBrowser to the value that Dreamweaver passes,

arguments[0]. Along with setting other default values, the function also sets result to a

default value of

false.

After variables are initialized, the

receiveArguments() function calls the user-defined

function

havePreviewTarget() and tests the result. If the result of the test is true, the

function checks to see if the user selected the primary or secondary browser. If so, the function

sets the variable

theBrowser to the path of the executable file that starts the browser

(

dw.getPrimaryBrowser() or dw.getSecondaryBrowser()). The function then performs a

loop that examines the list of browsers returned by

dw.getBrowsersList(). If the path to a

browser in the list matches the path to the primary or secondary browser, the function sets the

variable

theBrowser to the matching value in browserList. This value contains the name of

the browser and the path to the executable file that starts the browser. If

havePreviewTarget() returns the value false, the function sets the variable theBrowser to

the value of the variable

whichBrowser.

Next, the

receiveArguments() function tests the variable theBrowser to make sure that it

does not begin with a path, that it is not

"undefined", and that it has a length greater than 0.

If all these conditions are true, and if the Site panel has focus, the

receiveArguments()

function calls the

site.browseDocument() function to invoke the selected browser with the

files selected in the Site panel. If the Site panel does not have focus, the

receiveArguments()

function calls the function

dw.browseDocument() and passes it the path of the current

document and the value of the variable

theBrowser, which specifies the name of the browser

with which to open the document.
