Adobe Photoshop CS6

JavaScript Scripting Reference JavaScript Object Reference 50

Application sample scripts

Application.jsx

This script invokes an alert box to display Properties important to an application such as version number,

the path to the application, the amount of memory available, and the number of documents open.

When a user presses the OK button on the alert box, a second dialog opens, which asks users whether they

would like the foreground and background colors set for the document presently open. If no document is

open, the script opens a new document for the user.

The script (with no document open) produces a progression of three dialogs.

//Create a Welcome message

// Use the name and version properties of the application object to

// Append the application’s name and version to the Welcome message

// use "\r" to insert a carriage return

// use the combination operator += to append info to the message

var message = "Welcome to " + app.name

message += " version " + app.version + "\r\r"

// find out where Adobe Photoshop CS6 is installed

// and add the path to the message

// add the optional parameter fsName to the path property

// to display the file system name in the most common format

message += "I’m installed in " + app.path.fsName + "\r\r"

// see how much memory Adobe Photoshop CS6 has to play with

message += "You have this much memory available for Adobe Photoshop CS6: " +

app.freeMemory + "\r\r"

// use the length property of the documents object to

// see how many documents are open

var documentsOpen = app.documents.length

message += "You currently have " + documentsOpen + " document(s) open.\r\r"

// display the message to the user

alert(message)

// answer will be true for a "Yes" answer and false for a "No" answer

var answer = confirm("Set the foreground and background to my favorite colors?")
