Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
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 Deluxe Tree such as in Deluxe 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.
Deluxe Tree works fast, but 10000 is a large value. Please, try atrial version of Deluxe 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 Deluxe Tree into the <table> or <div>.
Q: I’m very interested in your script of deluxe-menu.
I tryed your script out and have some questions now:
How do I highlight main menu items when I selected a main category?
How do I highlight submenu items when I selected a sub category?
How can I have a submenu unfoldet when I selected the matching main category?
I would be pleased to have answers to my questions as soon as possible.
Thank you for support!
A: The menu has only two states normal and mouseover. We'll try to add the pressed state in the future.
You can set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
Q: Can you tell me why these two simple dhtml tabs menus are conflicting and overwriting?
A: Notice, when you have several dhtml tabs menus on the one page you should calldtabs.js file only once.
<script type="text/javascript" src="Top_Center1.files/dtabs.js"></script>
Q: Is there a way to programmatically specify which tab is selected in the drop down menu using javascript?
What I mean is, I want to set the selected tab programmatically (Not clicking the tab).
A: Deluxe Tabs doesn't support API functions which can return theselected tab.
If your site is written on PHP you can set "bselectedItem" and "varbselectedSmItem" parameters based on your link beforeyou call your data file.
For example, move "bselectedItem" and " var bselectedSmItem" parametersfrom your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=<?php echo $seltabs; ?>;
var bselectedSmItem=<?php echo $selsmtabs; ?>;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
You should define seltabs and selsmtabs using server side script.
You can also set it on every page before you call data.js file, forexample:
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=4;
var bselectedSmItem=3;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
