Q: Can I use javascript to get the object (getElementByID). If not howdo I hide my dropdown menu on print?
A: You can add a new button to print your page and call onClick event, soyou should write:
<body ....
onClick="document.getElementById('dm0m0').style.visibility='hidden'; window.print();">
...
</body>
Or you can use the same javascript code from your menu item.
For example:
var menuItems = [
["Print", "javascript:document.getElementById('dm0m0').style.visibility='hidden';
window.print();", icon1, icon2],
];
But if you want to hide the menu when your customers push "File/Print"you should write so:
You must create two functions, for example:
function myprint()
{ document.getElementById('dm0m0').style.visibility='hidden';
window.print();
}
function myprint2()
{ document.getElementById('dm0m0').style.visibility='visible';
window.print();
}
You should add this functions into your code.
And then you must write so:
window.onbeforeprint = myprint;
window.onafterprint = myprint2;
Q: I'm a having an issue with my dhtml dropdown menus poping-up behind a flash object on a page. The key to this issue is that the menus work perfectly in our non-secure (HTTP) development environment, but do not work correctly on our secure (HTTPS) beta environment. The code on the 2 environments is exactly the same, and the beta environment does work when viewed in HTTP. Both the flash object and the Deluxe-Menu are called using relative paths, not absolute paths.
Please let me know what additional information you need from me. I appreciate any help you can provide.
A: Check that you're using latest version of engine files - v3.3.
You should add "opaque" parameter for <object> and <embed> tags.
See, how you should install flash on your pages.
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" height="150"

Q: Is it possible to insert a dhtml foldout menu item at the top of the submenu? For example, if a dhtml foldout menu is defined as:
var menuItems = [
["Search","","","","","","1","0"],
["|Residential","srch.php","","","","","0"],
["|VacantLand","srch.php?cri","","","","","0"],
["|Commercial/Industrial","srch.php","","","","","0"]];
How can I add a new item above “Residential?” I’ve tried the following with no luck — the forth argument does not seem to be used:
dm_ext_addItem(0, 1, ["New Sample", "testlink.htm", "", "", "Your Sample Tooltip", "middle", 0], 0)
A: To insert item in the specific position you should use thefollowing function:
function dm_ext_addItemPos (menuInd, submenuInd, iParams, Pos)
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>.
