Q: What can I do to optimize the load time for dhtml rollover
and prevent reloading it from the server with every page reload.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: How do I set just one sub menu link to open in a new window for the css dhtml menu
when the rest is set to _self ?
A: You can set item's target for each item individually:
["Home","testlink.htm", "default.files/icon1_s.gif", "default.files/icon1_so.gif",
"", "Home Page Tip", "_blank", "", "", "", ],
Q: How do I expand the length of the vista html drop menu tab images to accommodate longer text? If the text is "Special Event Programs", the arrows are outside the tab in another partial one. I am using the Vista style tabs (black_blue / tealblack).
Is there any way other than definition of new image files to get more color combos?
Can I change the text size in the menu tabs? When I use the Tuner, it has no effect.
A: Try to use image-based menu.
Set:
var menuWidth="92px";
var menuHeight="";
and create the following style:
var itemStyles = [
["itemBackImage=WANmenu.files/btn_magenta-back.gif,WANmenu.files/btn_magentablack-back.gif",
"beforeItemImage=WANmenu.files/btn_magenta-left.gif,WANmenu.files/btn_magentablack-left.gif","afterItemImage=WANmenu.files/btn_magenta-right.gif,WANmenu.files/btn_magentablack-right.gif","beforeItemImageW=10","afterItemImageW=10","beforeItemImageH=21","afterItemImageH=21",
"itemBorderWidth=0","fontStyle=normal11px Tahoma","fontColor=#FFFFFF,#FFFFFF"],
];
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>.
