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: Is it possible for dhtml vertical tabs to have a link on page that links to
second page by passes the default setting then selects and displays
the information in the tab you need?
A: You can use the following function to open specific tab:
dtabs_itemClick(menuInd,itemInd);
where
menuInd - index of a tab menu on a page, >= 0.
itemInd - index of a item, >=0.
For example:
<DIV onClick="dtabs_itemClick(0,2)" style="width: 200px; border: 2px solid #000;">
Click to open the third tab
</DIV>Q: I am trying to have the selected top menu w dhtml item remain on the mouseover event after it is selected. It seemed to be working fine when i was just testing with # as a link but when i actually linked to different pages it returns to normal. How do i get this to work.
I tried removing the variable from the data file and calling it using
<script type="text/javascript" language="JavaScript1.2"> var pressedItem=set 1,2,3 depending on page </script>
but this does not seem to work as it does for tabs.
A: You can find more info here:
http://www.deluxe-menu.com/highlighted-items-sample.html
Deluxe Menu has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, forexample:
<noscript><a href="http://deluxe-menu.com">menu w dhtml 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=3;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also 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: I would like to know how to put the items for the popup menu on multiple lines (i.e. create a line feed), how do I tell my code to start a new menu item on the NEXT line?
A: There are 2 ways to do that:
1. set
var noWrap=0;
2. use
tags, for example:
var menuItems = [
["|Here is where <br> I would like
to have a line<br> feed",,"","", "", "", "", "", "", "", "",],
];
