Export all open files to jpeg = bug?

Question

hi there!
I'm currently writing a script that exports all the open documents to a JPEG.
this works except for one little thingy:
instead of exporting all the documents, it exports only the active one, with all the other document names...
so for example:
3 files opened, 3 files exported with a different, correct filename, BUT every jpeg shows the active file.
I don't know what I'm doing wrong, so if someone could jump in = AWESOME!
TY!
M.
this is my code:
try {
    if (app.documents.length > 0 ) {
        // Get the folder to save the files into
        var destFolder = null;
        destFolder = Folder.selectDialog( 'Select folder for JPG files.', '~' );
        if (destFolder != null) {
            var options, i;
            // Get the Flash export options to be used.
            var options = new ExportOptionsJPEG();
            // You can tune these by changing the code in the getOptions() function.
            for ( i = app.documents.length-1; i >=0 ; i-- ) {
                // Get the file to export the document as swf intos
                var targetFile = new File( destFolder + '/' + app.documents[i].name +".jpg");
                // Export to flash
                app.documents[i].exportFile(targetFile, ExportType.JPEG, options);
                app.documents[i].close();
            alert( 'Documents exported as JPG' );
    else{
        throw new Error('There are no document open!');
catch(e) {
    alert( e.message, "Script Alert", true);

Changing your 'for' loop to a 'while' loop and working with 'activeDocument' rather than documents[i] works fine for me…
Like so…
try {
    if (app.documents.length > 0 ) {
        // Get the folder to save the files into
        var destFolder = null;
        destFolder = Folder.selectDialog( 'Select folder for JPG files.', '~' );
        if (destFolder != null) {
            var options, i;
            // Get the Flash export options to be used.
            var options = new ExportOptionsJPEG();
            // You can tune these by changing the code in the getOptions() function.
            while (app.documents.length > 0) {
                // Get the file to export the document as swf intos
                var targetFile = new File( destFolder + '/' + app.activeDocument.name +".jpg");
                // Export to flash
                app.activeDocument.exportFile(targetFile, ExportType.JPEG, options);
                app.activeDocument.close();
            alert( 'Documents exported as JPG' );
    else{
        throw new Error('There are no document open!');
catch(e) {
    alert( e.message, "Script Alert", true);
