Q: We currentlly have a menu that uses standard html hyperlinks to open a new window with _blank as the target. Unfortunately, the size of the window is controlled by the browser and we want to be able to control it. The only way that we know how to do that is to use the window.open client-side function and pass the window's dimensions. Here is a sample of the code that would do that:
window.open("url","_blank","height=1024,width=768,status=yes,toolbar=no,menubar=no,location=no");
How can we add the javascript code to the dhtml menu vertical instead of a link? Do you have any samples?
A: You can use javascript code within menuItems, for example
Write:
["Test Window","javascript:window.open('http://www.microsoft.com','_blank','height=1024,width=768,status=yes,toolbar=no,menubar=no,location=no');", , ,'Monitor Exceptions' , , '0', '0',,],
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: How would I use the submenu feature to display itself only if a person is logged in. such as if a person logged in then the member area would expand, else it would always stay closed with only the login username section showing?
A: Unfortunately it is not possible. You can only add items depending onthe logged user.
You should use API functions:
see more info:
http://deluxe-menu.com/functions-info.html
For example, you can use:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
function dtreet_ext_deleteItem (menuInd, itemID)
function dtreet_ext_showItem (itemID, visibility)
function dtreet_ext_expandItem (itemID, expand)
Q: As a part-time webdeveloper I have gotten very interested in your product. I really appreciate a number of things
- it's very flexible
- it's very easy to work with
- examples nicely show the capabilities
But I have a couple of questions:
- When opening a menu, there is an option for keeping the menu-item that has been pressed hightlighed (so that the user can see what he/she pressed). Is it possible, programmatically, to decide when this highlighting should be removed? The scenario is that, when a menu-item is clicked the used might browse for a couple of pages within the context defined by the menu-item, but when the user leaves, the menu-item should no longer be highlighted. I will (programmatically) decide the context, but is it possible for me to interact with the menu, and for example decide explicitly which menu should be highlighted?
- Our design department would like the menu containing the elements: "Skovdrift, Juletreer, Skovrejsning, etc". Please notice that "Brende" is supposed to show a menu item that is hightlighted. Is is possible to create this menu such that it is dynamic and each item is text-based (and not based on two pictures for each menu-entry: hightlighted and not)? I've been wondering how to solve this problem, but I cannot figure out a solution. The problem that I is stuck at, is how organise this speciel "frame" around each menu-element. Something that be partly accomplished using "arrowImageMain", but that does not bring me all the way. Please notice that the menu-items might not have any sub-menu.
A: I suppose that you're saying about
var pressedItem=-2;
Defines an item that will appear in the highlighted state
(-2 - normal mode, -1 - toggle mode is active, but highlighted item not defined, 0,1,2,3,... - # of pressed item including separators)
This parameter will not approach you.
You should set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
