Q: In my previous email asking about your menu program's ability to display a different color word on a menu item when the site is on that selected page, I made a mistake - I was experimenting with Vista xp1 style, the black/blue shiny dhtml menu templates.
A: The menu has only two states normal and mouseover. We'll try to add the pressed state in the future.
You can 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.
Q: One other issue I am having if you don't mind helping. On my web site when I run the menu I get an Errors on page message with the following
Line: 16
Char: 18132
Error: Access is denied.
Code: 0
URL: http://www.site.id.au/left_frame.htm
When I run the site from my local PC with the menu, I don't get this error?
Could you possibly suggest why? I can't find anything on your site.
A: Try to check all you paths.
original setting:
var tmenuBackImage="";
var titemBackImage=["",""];
changed to:
var tmenuBackImage="images/blank.gif";
var titemBackImage=["images/blank.gif","images/blank.gif"];
Try to specify units in "px".
var tmenuWidth = "180px";
It's necessary to specify exact value for Mozilla browsers. It helpsto position menus correctly.
You should set this parameter:
var tmenuHeight = "auto";
Now you have such parameters in the menu:
["||24","C:/Documents and Settings/Paul/My Documents/My Web Sites/site.id.au/guide/24.htm", , , , , "main_frame", , , , , ],
["||30 Days","C:/Documents and Settings/Paul/My Documents/My Web Sites/site.id.au/guide/30days.htm", , , , , "main_frame", , , , , ], ["||Battlestar Galactica","C:/Documents and Settings/Paul/My Documents/My Web Sites/site.id.au/guide/battlestarg.htm", , , , , "main_frame", , , , , ],
["||Blade","C:/Documents and Settings/Paul/My Documents/My Web Sites/site.id.au/guide/blade.htm", , , , , "main_frame", , , , , ],
["||Eureka","C:/Documents and Settings/Paul/My Documents/My Web Sites/site.id.au/guide/eureka.htm", , , , , "main_frame", , , , , ],
["||I Pity the Fool","C:/Documents and Settings/Paul/My Documents/My Web Sites/site.id.au/guide/ipitythefool.htm", , , , , "main_frame", , , , , ],
You cannot use local paths on your website.
Please, correct it. <
br>You should write for example: ["||24","site.id.au/guide/24.htm", , , , , "main_frame", , , , , ],
["||30 Days","site.id.au/guide/30days.htm", , , , , "main_frame", , , , , ],
["||Battlestar Galactica","site.id.au/guide/battlestarg.htm", , , , , "main_frame", , , , , ],
Try to use also the attached engine .js files on your server.
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: Does your site navigation menu support RTL Pages? How hard it is to convert it this way?
A: var dmRTL = 0;
Set this parameter to 1 if you're using right-to-left direction of html page <HTML dir=rtl>.
