Q: Im working on a menu with your program, and am unable to make the javascript sticky menu save the hover states after you move off the navigation item and onto its child nav items.
For example
Example Nav item 1
-Example Sub Nav item 1
-Example Sub Nav item 2
-Example Sub Nav item 3
When I hover on the Example Nav Item 1, the hover state works, but when I move my mouse down (Im using a horizontal javascript sticky menu) to select Example Sub Nav item 1, I want the hover state to stay selected on the "parent" Nav Item. Is this possible? What is the variable you have to change to accomplish this?
A: Yes, it's possible, please use
var saveNavigationPath = 1; The javascript sticky menu keeps items highlighted during menu navigation.
0 - disabled, 1 - enabled (default).
Q: I need to load a tab page and have the correct javascript menu rollover tab showing based on a variable that is available when the page loads. How do I get the tab to change to a different tab then the one defined in the configuration file?
Example
bmenuItem = 0; /* this is the default */
When my page reloads I want bmenuItem = someVariable;
How do I do this?
A: Deluxe Tabs doesn't support API functions which can return theselected javascript menu rollover tab.
You can set "bselectedItem" and " var bselectedSmItem" parametersbased on your link before you call your data file.
For example, move " var bselectedItem" and " var bselectedSmItem" parametersfrom your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=<?php echo $seltabs; ?>;
var bselectedSmItem=<?php echo $selsmtabs; ?>;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
You should define seltabs and selsmtabs using server side script.
You can also set it on every page before you call data.js file, forexample:
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=4;
var bselectedSmItem=3;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
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 Javascript/DHTML Tree such as in JavaScript Tree 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.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML 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 Javascript/DHTML Tree into the <table> or <div>.
Q: I want to be able to have all of the submenus start at the top of the menu. For example, when I hover across each of my menu items in a vertical level, I want the sublevel menu to start at the very top of the menu, not out beside the menu option. How can I achieve this
A: You can have such effect only for the first subitems.
Others subitems will have Y offset.
Please, see the attached example.
You should adjust the following parameters:
var topDX=-116;
var topDY=-31;
var DX=-148;
var DY=-32;
