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 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"]
];
Q: On my website I am a total of 2 menus being generated. How do I correctly generate "SE-Friendly Code" if I have 2 menu in javascripts? The "DM Links" code that is being generated will have a few of the same dm id because the menus are created seperate. How do I get it so each menu will have different dm id with no overlaps?
A: The identifiers in these links are additional parameters.
<div id="dmlinks" style="font:undefined;color:#000000;text-decoration:none">
<a id="dmI0" href="testlink.html">Home</a>
<a id="dmI2" href="testlink.html">Features</a>
<a id="dmI4" href="testlink.html">Description of Files</a>
You can delete these identifiers or leave them.
So, if you have several menu in javascripts on the same page you should generate twoblocks of search engine friendly code and add them on your page.
Q: I was looking for a feature to reverse the order of items added dynamically to the drop down html menu
I'm not sure where to find it or how to go about getting this new feature incorporated into my code.
Could you please help me and tell me where to go next?
A: To add your items dynamically in the specific position you should usethe following function:
dm_ext_addItemPos(mInd, smInd, iParamsArr, Pos)
where Pos - the position in the menu where you want to add new item(starts with 0).
Check that you have dmenu_dyn.js file in the same folder with dmenu.js
file and set
var dynamic=1;
parameter.
