To find all items in your document of a certain type you can use document.getItems(attributes):

var allPaths = document.getItems({
	type: Path
});

for (var i = 0; i < allPaths.length; i++) { 
	var item = allPaths[i];
	item.strokeColor = '#ff0000'; 
}

Thanks Jonathan. However now it just gets stuck on the first line, saying document is undefined. Is there anything else I should put before that code?

Thanks

That sounds like you don't have an open document when you execute the code. The global document variable only returns a valid document if there actually is one.

There's definitely a document open when I run the code. As a test I created a new document, drew a few lines and ran the code from the ExtendedScript Toolkit and get the error. See attached screenshot. Thanks.

I'm not entirely sure but you should probably write your script in an other script editor...

Thanks all for your help. By looking through the Illustrator Javascript reference I've found that this code works:

// Define the new color
var newRGBColor = new RGBColor();
newRGBColor.red = 255;
newRGBColor.green = 0;
newRGBColor.blue = 0;

//Color all paths
var allPaths = app.activeDocument.pathItems
 
for (var i = 0; i < allPaths.length; i++) { 
    var item = allPaths[i]; 
    item.strokeColor = newRGBColor; 
}

Stef, you are using Adobe's ExtendScript engine. This site here is dedicated to the Scriptographer plugin that you can download here. They are two completely different things, and code written for one does not work on the other.

We will not be able to help with scripts for Adobe ExtendScript, but there are plenty of other sites that offer help, for example on the Adobe Forums.

But if you are curious to learn thing the Scriptographer way, you may want to start by looking at the Tutorials, and we are happy to answer your questions in this forum.

Hi Jürg, thanks for clarifying that, that explains it now. I obviously didn't look around the site enough before posting. However thanks for your help and I'll look into using scriptographer for any future scripting needs.
