Q: Is there a way to programmatically specify which tab is selected in the drop down menu using javascript?
What I mean is, I want to set the selected tab programmatically (Not clicking the tab).
A: Deluxe Tabs doesn't support API functions which can return theselected tab.
If your site is written on PHP you can set "bselectedItem" and "varbselectedSmItem" parameters based on your link beforeyou call your data file.
For example, move "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: I have problem with our characters also, the иж№рѕИЖ©Р® are all messed up. The program doesn't work on iso-8859-2 charset.
How can I change the charset of the code it generates? I did in templates, bt generator still generates the menu in windows-1250 charset.
Well, I can edit by hand later but...
A: You should set charset attribute on your page:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-2" />
Unfortunately, you can't see these characters correctly in Deluxe Tunerapplication.
Q: There is the possibility in the menu that an item has access control, that is is visible or not depending of the user?
A: You can use Javascript API and write your own code.
See more info here:
http://deluxe-menu.com/functions-info.html
You can use
dm_ext_changeItem (menuInd, submenuInd, itemInd, iParams)
to disable your items or
dm_ext_changeItemVisibility (menuInd, submenuInd, itemInd, visibility)
to hide your items.
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>.
