How to take an existing script and apply it to multiple documents

[ratsurfer1]

I would like to take an existing script, but have it run on multiple documents that I have open (or select from a set of unopened files)

For example, run the ExportAllStories.jsx on multiple documents

Is there a chunk of text I can just copy and paste into it to make this happen?

When I need something like this, I use this code I wrote sometime ago...

TO RUN IN FILES SAVED IN A FOLDER:

//=============================================================
//  Script by Luis Felipe Corullón
//  Contato: lf@corullon.com.br
//  Site: http://lf.corullon.com.br
//=============================================================
var myFileFolder = Folder(/*HERE GOES THE DEFAULT FOLDER*/).selectDlg("Select the folder.");
var myDialog = myFileFolder;
if (myDialog != null) {
    var myIDFiles = myFileFolder.getFiles("*.indd");
    alert (myIDFiles.length + " files were found in the selected.","Script by LFCorullón");
    for (var z = 0; z < myIDFiles.length; z++) {
        app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
        app.open(File(myIDFiles));
//~ =========================================================================================================
//~ =========================================================================================================
// HERE GOES THE CODE TO BE EXECUTED IN EACH FILE
// HERE GOES THE CODE TO BE EXECUTED IN EACH FILE
//~ =========================================================================================================
//~ =========================================================================================================
        app.activeDocument.close(SaveOptions.YES);
        app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL;
        }
    }

TO RUN IN FILES SAVED IN A FOLDER AND ALL SUBFOLDERS:

//=============================================================
//  Script by Luis Felipe Corullón
//  Contato: lf@corullon.com.br
//  Site: http://lf.corullon.com.br
//=============================================================
var myFolder = Folder(/*the specified folder here*/).selectDlg("Select the main folder.");
// se o usuário pressionar OK na JANELA DE DIALOGO
var myDialog = myFolder;
if(myDialog == null){
        alert ("Canceled.","Script by LFCorullón");}
else {
    var myFiles = [];
    GetSubFolders(myFolder);
    alert (myFiles.length + " files found in the main folder and subfolders.","Script by LFCorullón");
//open files in the selected folder and subfolders
for(var i = 0; i < myFiles.length; i++)
    {
//não exibe nenhuma janela de interação.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
//turn check links off
app.linkingPreferences.checkLinksAtOpen = false;
    app.open(File(myFiles));
//~ =========================================================================================================
//~ =========================================================================================================
// EXECUTA A AÇÃO EM CADA UM DOS ARQUIVOS DA PASTA SELECIONADA
// EXECUTA A AÇÃO EM CADA UM DOS ARQUIVOS DA PASTA SELECIONADA
//~ =========================================================================================================
//~ =========================================================================================================
//turn check links on again
app.linkingPreferences.checkLinksAtOpen = true;
//exibe todas as janelas de interação.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL;
    }
alert (myFiles.length + " files in the main folder and subfolders were processed.","Script by LFCorullón");}
function GetSubFolders(theFolder) {  
     var myFileList = theFolder.getFiles();  
     for (var i = 0; i < myFileList.length; i++) {  
          var myFile = myFileList;  
          if (myFile instanceof Folder){  
               GetSubFolders(myFile);  
          }  
          else if (myFile instanceof File && myFile.name.match(/\.indd$/i)) {  
               myFiles.push(myFile);  
          }  
     }  
}

Hope it help.
