The same name of the channel, is the same pattern. How to keep different channel names, and delete redundant channels with the same name

all channel：1,4,2,1,2,3,1,3,2,4------->channel:1,4,2,3

Hi Roychen,

Hope this will help... 🙂

var dup=[];
if(app.documents.length>0){
	var docRef = app.activeDocument;
	var mychan = docRef.channels;
	var l=mychan.length;
	while(l--) {
		var mychans=mychan[l].name;            
		if(dup.toString().indexOf (mychans)==-1){
			dup.push(mychan[l].name);
		}
		else{mychan[l].remove();}
	}
}

Hi Rochan,

Try this code.. 🙂

var dup=[];
if(app.documents.length>0){
	var docRef = app.activeDocument;
	var mychan = docRef.channels;
	var l=mychan.length;
	while(l--) {
		var mychans=mychan[l].name;
		if(searchStringInArray (mychans, dup)==-1){ 
			dup.push(mychan[l].name);
		}
		else{mychan[l].remove();}
	}
}

function searchStringInArray (str, strArray) {
	for (var j=0; j<strArray.length; j++) {
		if (strArray[j]==str) return j;
	}
	return -1;
}

o = {}, chnnls = [].slice.call(activeDocument.channels); while(chnnls.length)
	!o[nme = (shft = chnnls.shift()).name] ? o[nme] = nme : shft.remove()
