bHavePreviewTarget
If a document, Text view, or the Code inspector have focus (
'document' || dw.getFocus() == 'textView' || dw.getFocus("true") == 'html' )
the function gets the DOM and checks to see if the document is an HTML or an XML
document. If so, the function sets
the value stored in
receiveArguments()
Dreamweaver calls the receiveArguments() function to let the command process
any arguments that pass from the menu item. For the Preview in Browsers menu,
the receiveArguments() function invokes the browser that the user selects.
The receiveArguments() function looks like the following example:
function receiveArguments()
{
var whichBrowser = arguments[0];
var theBrowser = null;
var i=0;
var browserList = null;
var result = false;
if (havePreviewTarget())
{
// Code to check if we were called from a shortcut key
if (whichBrowser == 'primary' || whichBrowser == 'secondary')
{
// get the path of the selected browser
if (whichBrowser == 'primary')
{
theBrowser = dw.getPrimaryBrowser();
}
else if (whichBrowser == 'secondary')
{
theBrowser = dw.getSecondaryBrowser();
}
// match up the path with the name of the corresponding browser
// that appears in the menu
browserList = dw.getBrowserList();
while (i < browserList.length)
{
if (browserList[i+1] == theBrowser)
theBrowser = browserList[i];
i+=2;
}
}
else
theBrowser = whichBrowser;
