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 would like to add the javascript API to a link contained in my website that will have the corresponding item in the deluxe-tree menu act as if it was "clicked".
Presumably I need to add the script (for example) <A HREF="http://deluxe-menu.com/features-info.html" TARGET="_self" "..javascriptHere ..">. Can you give me an example please of what code goes into there.
I presume I use dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion) but where do I get the ????Ind data from and make the javascript call in the above link.
A copy of a working example together with where to get the data , perhaps on your own web pages, would help.
A: Deluxe Tree doesn't save a presseditem as it saves a tree state. It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function dtreet_ext_setPressedItem (menuInd, itemID)
<script type="text/javascript">
var i = <?php echo $selitem; ?>;
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
</script>
You should define selitem using server side script.
Q: Is there a way to have the sub menus open to the left instead of the right?
A: You should set the following parameter:
var smViewType=2;
Q: If I open a pdf file within the frame work, the javascript onmouseover menu does not work.
A: Try to load your .pdf file into the IFRAME, for example on yourcontent frame (frame where you load your pdf files) you'll have:
<iframe src="files/1.pdf" name="iframe" style="z-index:0;" width="100%" height="100%"></iframe>
Submenus will overlap PDF correctly if you load it in the IFRAME only!
