Tree menus are menus that pop open when a little graphic placed to the left of the menu item is clicked -- very similar to Microsoft Explorer expanding and collapsing folders of files. Usage: make_tree_menu(id); -or- make_tree_menu(id,omit_symbols,no_save_state,singular,no_setup) where id is the id attribute of the beginning
    tag. There are four optional arguments. The omit_symbols argument, if set to true, omits adding symbol tags to the beginning of each menu item. The no_save_state argument prevents the open/close state of the menus from being saved in a browser cookie. The singular argument, if true, restricts the open menus to only one per level. The no_setup flag prevents nav from scanning the document to setup the menu. This flag assumes that the server has constructed a complete menu with appropriate symbols, click event handlers, and class attributes. The optional arguments can be alternately specified by setting the configuration variables before calling make_tree_menu(). Menus are created out of
      tags and their enclosed
    • tags. The
    • tags can contain other
        tags. Symbol objects (e.g. tags) are (optionally) inserted before each
      • tag. The class name of the symbol tag is set to one of the nav class variables: SymbolClassOpen, SymbolClassClose, or SymbolClassItem depending upon if the
      • tag has enclosed
          tags and whether the saved open/closed state of the menu's
            tag is 1 or 0. Menu open/closed states are preserved in a cookie with a name derived from the menu's first
              tag's id. When the user clicks on a symbol tag, the menu is opened or it is closed if it is already open. The symbol's CSS class is changed to the SymbolClassOpen or SymbolClassClose appropriately. To allow more animation, the
            • tag's class has the class name in the variable ClassOpen appended to it. This doesn't change the class name, it adds a new class name. When the menu is closed, the added class name is removed and the class name in the variable ClassClose added to it. The type of a symbol's tag inserted before each
            • tag item is determined by the class variable SymbolTag. It can be set to "span" or "div" or it can be empty. The default value is "span". A symbol is NOT inserted at the
            • tags' beginning if the SymbolTag is set to null or the empty string. Also, a symbol is NOT inserted at the beginning of the
            • tags if the configuration variable nav.OmitSymbols is true (default is false). This allows the server to insert the symbol tags and have this JavaScript operate the symbols. You can use regular tags as buttons to open and close menus by defining an onclick handler like: Submenu If the button is outside of the menu structure, pass nav.toggle() the id of the menu/submenu you want to toggle instead of "this". Toggle Submenu -or- Show Submenu -or- Hide Submenu The nav.show(ul) and nav.hide(ul) shows and hides one branch of the tree menu. The nav.show_all(ul) and nav.hide_all(ul) shows and hides every branch of the tree menu. nav.save_state(ul) saves the current open/close menu states -- usefull after nav.show_all() or nav.hide_all(). nav.reset(ul) resets the menu back to the original default state. It does that by removing the cookie that saves the menu state. The page needs to be refreshed to actually display the menu in its original state. Multiple menus can be made and each menu can have different settings for the configuration variables. Changes from nav v1.3: - Added use of IMG tags for SymbolTag. This allows the program to change both the forground images and the background image. Added nav.SymbolSrcOpen, nav.SymbolSrcClose and nav.SymbolSrcItem variables. - Added nav.Singular flag to restrict open menus to just one per menu level, and added fourth optional argument to make_tree_menu() to turn on the flag for an individual menu. - Added nav.save_state() utility to save menu open/close states. - Added nav.OmitSymbols to refrain from inserting symbols into the list but yet operate them if found. - Added nav.SetupMenu flag to keep nav from scanning the document. This allows the server to build the menu instead of nav assembling the menu after the document is loaded. This greatly speeds up the rendering of large menus -- especially with IE6 where accessing the document objects is so very slow. ******************************************************************************/ /////// Configuration Variables /////////////////////////// nav.SymbolTag = 'span'; // symbol inserted at beginning of
