Counting files in a folder and showing results in an alert window.

Question

Hello all.
I would like to get the script to count the number of files in a selected folder.
I have a UI where there are browse, ok and cancel buttons.
I wanted the OK button to show the number of jpeg files in the selected folder. If no folder is selected, and the OK button is pressed, it would prompt the user to select a folder before pressing the OK button.
Thanks!

all you need to learn scripting is in the "JavaScript Tools Guide", you're making some progress but reading that and following the samples will make things clear and speed the learning proccess up.
if you look at your code there's only one function, it is called when the Browse button is clicked. See how it is constructed and write another similar function for the Ok button, in there read the contents of the label box and create a folder with that path, then call the function to read the files.
dlg.Panel1.okBtn.onClick = function (){
   selectedFolder = new Folder(decodeURI(dlg.Panel1.Path.text));
   if (selectedFolder.exists)
        doSomething (selectedFolder);
   else
        alert("select a folder first...");
dlg.center(); //center dialog box on screen
dlg.show(); //show dialog box
function doSomething(folder)
        files = folder.getFiles();
        alert(files.length + " Files in selected Folder");
        alert(files);
