/* == PHP FILE TREE JAVASCRIPT EXTENSION == Based on the Expandable Listmenu Script by Daniel Nolan http://www.bleedingego.co.uk/webdev.php Modified by Cory S.N. LaViska http://abeautifulsite.net/ == WHAT IT DOES == This script makes the nested lists created by PHP File Tree expand and collapse dynamically. == USAGE == Include the script into the section of the appropriate page(s) as shown below: All file trees generated by PHP File Tree will automatically collapse to the top level (as specified by $directory) and become dynamic. == FAQS == Q Can I have more than one file tree on one page? A Yes. You can have as many as you want and they will all function as expected. */ function init_php_file_tree() { if (!document.getElementsByTagName) return; var aMenus = document.getElementsByTagName("LI"); for (var i = 0; i < aMenus.length; i++) { var mclass = aMenus[i].className; if (mclass.indexOf("pft-directory") > -1) { var submenu = aMenus[i].childNodes; for (var j = 0; j < submenu.length; j++) { if (submenu[j].tagName == "A") { submenu[j].onclick = function() { var node = this.nextSibling; while (1) { if (node != null) { if (node.tagName == "UL") { var d = (node.style.display == "none") node.style.display = (d) ?
