How to create numbered PDF bookmarks

This script will prepend a single number to each bookmark like this:

but it could be modified to use the numbering style that you indicated. Here is the code. If you need help installing it or running it, please contact me offlist. rick at frameexpert dot com

if (app.viewerVersion >= 10) {

	// Add a toolbutton for the command.
	app.addToolButton({cName: "AddBookmarkNumberingCmd",
		cTooltext: "Add Numbers to Bookmarks",
		cExec: "addBookmarkNumbering ();",
		cEnable: "event.rc = (event.target != null);",
		nPos: -1 });

} 
else { // 9 or below.

	// Add the command to the Document menu.
	app.addMenuItem({cName: "AddBookmarkNumberingCmd",
		cUser:"Add Numbers to Bookmarks",
		cParent: "Document",
		cExec: "addBookmarkNumbering ();",
		cEnable: "event.rc = (event.target != null);" });
}

function addBookmarkNumbering () {

	numberBookmarks (this.bookmarkRoot);
}

function numberBookmarks (bkm) {
  
	var regex, i, count, text;

	regex = /^\d/; // Starts with a number.
	
	if (bkm.children != null) {
		// How many children of this bookmark, including the root?
		count = bkm.children.length;
		// Process all of the children bookmarks.
		for (i = 0; i < count; i += 1) {
			// Make sure the bookmark isn't already numbered.
			if (regex.test (bkm.children[i].name) === false) {
			    // Prepend the number to the bookmark.
			    bkm.children[i].name = (i + 1) + ". " + bkm.children[i].name;
			}
			// Call this function recursively so all bookmarks are touched.
			numberBookmarks (bkm.children[i]);
		}
	}
