Recent Questions Javascript Tree Menu Script
Q: Firstly I'd like to say it looks like a great product. Something that would definitely be of use for our corporate intranet. But first! I have a problem with the evaluation.
I'm trying to get a click/context menu from clicking an image but no matter what I try the following .htm file errors with object required on line 15. I've read your examples / source over and over again but no joy - If I just display the menu with the usual <script> menu.js etc. entry it works but not with a popup?
Please please help if you can?
PS I've set the popupMode variable to 1 in the menu definition file.
A: The installation of your Popup menu is not correct.
If you have only one menu on your page you should write
<img src='images/note.gif' oncontextmenu='return dm_popup(0 ,2000 ,event );'>
You should also copy dmenu_popup.js file into the same folder withdmenu.js file.

Q: How does one go about changing the parameter or the menu in java script so that a menu selection stays 'on'?
In other words, the menu remains selected, perhaps in a background color that shows the user this menu choice is selected and the user is in the selected menu area.
A: To save your navigation path you should set the following parameter:
var saveNavigationPath = 1;
The menu keeps items highlighted during menu navigation.
0 - disabled, 1 - enabled (default).
You can highlight menu items by default in two ways:
1) Set the pressed item on each page idividually using the following parameter:
var pressedItem = -2;
The toggle mode. Sets an index of an item that will be highlighted by default.
-2 - the toggle mode is disabled;
-1 - the toggle mode is enabled, but no items highlighted by default;0,1,2,3,... - index of highlighted item in a top-level menu.
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, for example:
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script >
<script type="text/javascript" src="menudir/dmenu.js"></script>
<script type="text/javascript"> var pressedItem=2;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
2) Set the pressed item/subitem using dm_ext_setPressedItem () function.

1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Javascript/DHTML Tree such as in JavaScript Tree Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Javascript/DHTML Tree into the <table> or <div>.
Q: Is there any way with my dynamic menu in javascript, to allow/setup the showing of path navigation at the top so the viewer sees where they are and where they have been (the path)?
A: You can only show the path in your status string. Set the followingparameter:
var statusString="link";
