Collecting all selected Items in Projects, including all items in folders

[Andrei Popa]

Please try to use as few global variables as possible. With many of them, it’s easy to just see where they have gone sideways as value. Just declare values locally and pass them as function argumentts. Also, try to put var in front of the for variable. I will try to reproduce your code as i would make it.

var selection = app.project.selection;

function findSel(selection){
var selAry = []

for (var i=0;i<selection.length;i++){
var currentItem= selection[i];

if(currentItem.typeName != "Folder"){
selAry.push(currentItem);
}else{
selAry.push(currentItem);
folderSearch(currentItem);
}
}

function folderSearch(myFolder){

for (var i=1; i<=myFolder.items.length; i++){
var curFolderItem = myFolder.items[i];

if(curFolderItem.typeName != "Folder"){
selAry.push(curFolderItem);
}else{
selAry.push(curFolderItem);
folderSearch(curFolderItem);
}
}
}

return selAry;
}

var mySelectedItems = findSel (selection);
alert(mySelectedItems)

The mySelectedItems variable is the array that contains the selected items. Last alert is just for checking.

Or we can make it like this so it looks even better:

var selection = app.project.selection;
var mySelectedItems = findSel (selection);
alert(mySelectedItems);

function findSel(selection){
var selAry = []

for (var i=0;i<selection.length;i++){
var currentItem= selection[i];

if(currentItem.typeName != "Folder"){
selAry.push(currentItem);
}else{
selAry.push(currentItem);
folderSearch(currentItem);
}
}

function folderSearch(myFolder){

for (var i=1; i<=myFolder.items.length; i++){
var curFolderItem = myFolder.items[i];

if(curFolderItem.typeName != "Folder"){
selAry.push(curFolderItem);
}else{
selAry.push(curFolderItem);
folderSearch(curFolderItem);
}
}
}

return selAry;
}

Thanks Andrei!
I will be testing it out in a while. But i think it looks like it works!

However, I have a question.
You defined folderSearch with “function folderSearch(myFolder). May I know what does (myFolder) here do?
Because I don’t see myFolder variable being called anywhere before this.

[Andrei Popa]

Its called parameter. You do not have to declare it in your program. You just use it inside your function. When you call the function, you insert what is called an argument instead of the parameter. Now the function replaces the parameter inside itself with the argument. Here is a short example to make it easier to understand:

testFunction("Message"); // alerts "Message"
testFunction("Another Message"); //alerts "Another message"
var myString = "The third message";
testFunction(myString); //alerts "The third message";

function testFunction(myValue){
alert(myValue);
}

It does not matter if you put the functions at the start or at the end of the program, they still load at the start. I suggest to put them at the end, and with suggestive names, so when you later read your code, you can see at a glance what it does.

Thanks for the help Andrei!

Hi Andrei, I’m still unclear and trying to learn more about function with arguments. However I can’t find a good example or site. Could I ask for you to point me in the right direction?
