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 have found (was it like this before??) that if I right-mouse-click over a menuitem then I do not see any option to open the URL in new window....
I do not get any options at all to open the URL in new window (or same window), in the browser context menu (both IE and Firefox).
A: No, Deluxe Menu doesn't have such a feature. This is only text, not alink. And we won't change it. Because now you're able to paste anyhtml code within menu item.
var menuItems = [
["<div>Arbeidsplaner</div>","cp_workplan.php",,,,"_self","0","0"],
You can write your links in the following way:
["Channels","", , , , , , , , ],
["|<a class='menu' href='http://google.com/'>google</a>","", , , , "_self", , , , ],
["|<a class='menu' href='http://google.com'>Market</a>","", , , , "_", , , , ],
And create a style:
A.menu {
color: #000;
text-decoration: none;}
A.menu:hover {
color: #000;
text-decoration: underline;}
Q: I'm testing out your cascading html menu but I cannot seem to see the live version of it on line. I can view it on my computer but I cannot send a link to my coworkers so they can view it also. Am I putting the code in the right location? Please point me into the right direction.
A: It is not correctly to call data file inside H2 tag
<h2> <script type="text/javascript" src="test1.js"></script></h2>
You should write
<script type="text/javascript" src="test1.js"></script>
or
<div>
<script type="text/javascript" src="test1.js"></script>
</div>
Check that you uploaded dtree.js and test1.js files on your server.
Q: Is there a way we can add javascript behaviors to the popup menu in java actions? For example, is there a way we can add an onClick function to a popup menu in java item (eg, onClick="return MyFunction( )" ) so that we can catch and process key events?
I'm really hoping there's a way of doing this...
A: Unfortunately, you can't assign onmouseover/onClick/onContextMenu event to each item. However, you can achieve this by using standard html objects within popup menu in java items, for example:
var menuitems = [
["<div onContextMenu='your_code_here'>item text</div>", ""]
];
You can use your own Javascript code instead standard links. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
