Functions in PhotoshopCreating a Function

If you are new to scripting for Photoshop, please view our Photoshop Scripting Basics tutorial for an introduction to Photoshop scripting and a few exercises about basic JavaScript.

Functions are a great way to keep large and complicated lines of code organized.

1. Type in the function keyword.

function

2. Enter the name for your Function followed by parentheses ( ). This name will be used everytime you want to tell your scirpt to run the function.

function myFunction()

3. Create an opening brace and closing brace {}. The brace will hold the code that will be run when you call myFunction().

function myFunction() {

}

4. Type in the code between the braces {};.

function myFunction() {
alert("This is a function");
}

5. Now everytime we want to use the alert, you can simply type in myFunction() instead. Run the script in Photoshop (File> Script> Browse) to ensure that it is working.

function myFunction() {
alert("This is a function");
}

myFunction();

Adding Parameters to a Function

You may also pass paramaters to functions making them more useful.

1. First type in the function code:

function sum() {

}

2. Type in the variables you would like to set inside the brackets. Seperate the variables by a comma.

function sum(myVar, myVar2, myVar3) {

}

3. Lets type an alert function to test the variables.

function sum(myVar, myVar2, myVar3) {
alert(a + b + c) ;
}

4. Call the function with the values of the variables inside the parenthesis ( ).

function sum(myVar, myVar2, myVar3) {
alert(myVar + myVar2 + myVar3) ;
}

sum(4, 6, 8)

5. Save and run the script inside Photoshop (File> Scripts> Browse). A pop-up should appear with the sum of 4 + 6 + 8.
