If you would like your subroutine to return a value, you must make it a function. Functions begin with the keyword Function. Subroutine The following subroutine, which is named HelloWorld(), simply displays a message box with the message Hello World. Sub HelloWorld() Alert "Hello World" End Sub To call the subroutine, you include it in a script. The following example displays a Hello World message when a user clicks CommandButton1. Private Sub CommandButton1_Click() HelloWorld End Sub Function The following script presents a form with one command button. When a user clicks the button, a dialog appears with the message Are you sure?When the user clicks a button, another dialog appears that displays the Boolean value of the clicked button: Yes = True; No = False. 'create a subroutine that calls the function DoConfirm 'and assigns it to the variable named Result Private Sub CommandButton1_Click() Result = DoConfirm("Are you sure?") Alert Result End Sub 'define the function Function DoConfirm(prompt) buttonPressed = Alert (prompt, vbYesNo) DoConfirm = (buttonPressed = vbYes) End Function JS In JavaScript, all subroutines are functions. The following sample script is a JavaScript version of the VBScript sample function in the previous example. /*create a variable and assign its value as the return value of the function named DoConfirm*/ var theResult = DoConfirm( "Are you sure?" ) //display an alert box with the assigned value as its message alert(theResult) //define DoConfirm function DoConfirm(message) { var result = confirm(message) return result Photoshop CS2 Adobe Photoshop CS2 Scripting Guide Scripting basics 31 } Executing JavaScripts from AS or VBS You can take advantage of JavaScript's platform-independence by running scripts from AppleScript or VBScript. You can execute either a single JavaScript statement or a complete JavaScript file. AS To run a JavaScript from AppleScript, you use the do javascript command. The following sample executes a single JavaScript command, which displays an alert box with the text alert text. do javascript "alert('alert text')" To pass a JavaScript file, you can create a reference to the file using as alias or to a reference to file as shown in the following examples set scriptFile to "applications: scripts: myscript" as alias do javascript scriptFile set scriptFile to a reference to file "applications: scripts: myscript" do javascript scriptFile Note: Refer to an AppleScript language guide or text book for information on referencing a file using either as alias or to a reference to file. VBS In VBScript, use the DoJavaScript method to execute a single JavaScript command. objApp. DoJavaScript ("alert('alert text')") To open a JavaScript file, use the DoJavaScriptFile method. The following sample opens a file on the D:\\ drive. Dim appRef As Photoshop. Application Set appRef = CreateObject("Photoshop. Application") appRef. DoJavaScriptFile ("D:\\Scripts\\MosaicTiles. jsx") Passing AS or VBS Arguments to JavaScript You can also pass arguments to JavaScript from either AppleScript or VBScript using the with arguments/(Arguments) parameter of the do javascript/DoJavaScript or DoJavaScriptFile command or methods. The following examples execute the following JavaScript, which is stored in a file named JSFile. jsx in your Applications\Scripts folder: alert( "You passed " + arguments. length + " arguments" ) for ( i = 0; i < arguments. length; ++i ) { alert( arguments[i]. toString() ) } AS tell application "Adobe Photoshop CS2" make new document do javascript (alias a path to the JavaScript shown above) ¬ with arguments {1, "test text", (fileApplications:Scripts:JSFile. jsx), ¬ current document} Photoshop CS2 Adobe Photoshop CS2 Scripting Guide Scripting basics 32 end tell VBS Dim appRef As Photoshop. Application Set appRef = CreateObject("Photoshop. Application") appRef. DoJavaScriptFile "C:\\Applications\Scripts\JSFile. jsx", _ Array(1, "test text", appRef. ActiveDocument) When running JavaScript from AppleScript or VBScript you can also control the debugging state. This example stores a reference to the document named MyDocument in a variable named docRef. If a document named MyDocument does not exist in the current document, the script displays a message. AS --Store a reference to the document with the name "My Document" --If "My Document" does not exist, display an error message tell application "Adobe Photoshop CS2" try set docRef to document "My Document" display dialog "Found 'My Document' " on error display dialog "Couldn't locate document 'My Document'" end try end tell Photoshop CS2 Adobe Photoshop CS2 Scripting Guide Scripting basics 34 VBS Private Sub Command1_Click() ' Store a reference to the document with the name "My Document" ' If the document does not exist, display an error message. Dim appRef As New Photoshop. Application Dim docRef As Photoshop. Document Dim errorMessage As String Dim docName As String docName = "My Document" Set docRef = appRef. ActiveDocument On Error GoTo DisplayError Set docRef = appRef. Documents(docName) Alert "Document Found!" Exit Sub DisplayError: errorMessage = "Couldn't locate document " & "'" & docName & "'" Alert errorMessage End Sub JS try { for (i = 0; i < app. documents. length; ++i) { var myName = app. documents[i]. name; alert(myName) } } catch(someError) { alert( "JavaScript error occurred. Message = " + someError. description) } Bibliography AS For further information and instruction in using the AppleScript scripting language, see these documents and resources: "AppleScript for the Internet: Visual QuickStart Guide, " 1st ed. , Ethan Wilde, Peachpit Press, 1998.
