How to check does psd file contains spot colours

[milevic]

I started making a script and i get stuck. Is it posible with javascript, from CMYK mode, to check does the psd(with multiply layers) contains spot(pantone) colors, and to make them hidden?

Thanks in advance.

BR,

I'm not following 100%, however, yes it is possible to check if there are spot colour channels in a file.

Ok, could you help me how?

Sorry, I don't have time now, you should be looking for:

ChannelType.SPOTCOLOR

If you search the forum or the web, I'm sure that you'll find something. If not, I'll revisit when I have time. 

Perhaps somebody else can answer before then. Good luck!

It is effective for learning if you post the code you wrote and get your opinion.
I wrote a simple example. I hope it will be useful.

var doc = app.activeDocument;
var count = 0;
if(doc.mode == DocumentMode.CMYK && doc.channels.length > 4){
    for(var i = 4; i < doc.channels.length; i++){
        if(doc.channels[i].kind == ChannelType.SPOTCOLOR){
            count++;
            }
        }
    }
alert(count? "is" : "none");

Thanks guys, this helped me, i just changed one part of your script, and I got what i need.

var doc = app.activeDocument;
var count = 0;
if(doc.mode == DocumentMode.CMYK && doc.channels.length > 4){
    for(var i = 4; i < doc.channels.length; i++){
        if(doc.channels[i].kind == ChannelType.SPOTCOLOR){
            doc.channels[i].visible=false;
            }
        }
    }
