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: What i need is when the menu item is clicked in the dhtml context menu, it'll run a json the onclick or mouseup event.
Is this possible?
A: You can achieve this by using standard html objects within items, for example:
var menuitems = [
["<div onContextMenu='your_code_here'>item text</div>", ""]
];
Actually you can use any html code within menuItems.
Q: With the new version, my body onload function is blocked.
In our application we do something with a body onload function.
It doesn't get called if I use the deluxe-menu. If I remove deluxe-menu js files from html, it works.
Is there a way I can use deluxe-menu and get my onload handler called?
A: Deluxe Menu detects any user's onload events and remember them in the case when you write a such events before dm_init(); call.
Try to delete onload event from <body> and write the following at theend of a page (after dm_init() call):
<script type="text/javascript"> onload = onloadHandler;</script>
That should work.
Q: Is there a way to get text to wrap on a tree menu rather then have scroll bars if the text is wider then the area?
A: To wrap your text you can use the following parameter:
var tnoWrap=0;
you can also use standard <br> tags.
["|Home aaaa aaaaaa aaaaaa<br>aaa aaaaaaaaaaa","testlink.htm", "default.files/icon1_s.gif", "default.files/icon1_so.gif", "", "Home Page Tip", "", "", "", ],
