Q: We are registered users of the JavaScript Tree Menu software. Today I tried to use the Javascript API, but there is something I do not understand and want to ask for support.
First, I set up a very simple menu:
var menuItems=[
['Menu 1'],
['|Submenu 1'],
['Menu 2'],
['|Submenu 2'],
];
This menu is built via dm_init().
Then, I inspect the menu (in Firebug):
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
Ok, there are three submenus. Now I am going to delete one of them:
>>> dm_ext_deleteItem(0, 0, 1)
"Menu 2" disappears on the screen, this works as expected. But now when I re-inspect the menu using the API, I find that the API reports exactly the same as before:
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
So, it seems the report function continues to know about the original menu structure and reflects it. Am I using the API in a wrong way?
The problem I want to solve is to remove the entire menu dinamico dhtml, in order to rebuild it dynamically. Because I did not see a function aimed to this functionality, my plan was to delete all main menu entries subsequently until the main menu inspector no longer reports an entry. Is there (a better) way to achieve this?
A: Unfortunately, dm_ext_deleteItem() only change visibility of theseitems.
It doesn't delete them completely.
We'll try to fix it in the next versions of JavaScript Tree Menu.
Q: Can you provide an example of how to dynamically change the menu items at runtime for the dropdown menus?
(asp is fine, but if it needs to javascript that is also ok)
A: 1) You can use API functions to affect items dynamically:
http://deluxe-menu.com/functions-info.html
2)Generate your menu items dynamically from database.
Unfortunately we don't have working example with ASP.
You may generate a menu from a database or XML using any server-side script, e.g., PHP, ASP, VB, etc.
However, these scripts don't work inside of Javascript .js files, so,
you should move parameters of a menu from a .js file into an html-page, e.g.:
<!-- JavaScript Tree Menu -->
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<!-- (c) 2008, http://deluxe-menu.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var menuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
</script>
The example of the menu working with PHP/MYSQL you can find here:

Q: Now I experiences a problem with the Danish letters in the dhtml drop down menu generator! I have changed the letters in the scriptfile - but this does not work.
Have we a problem with Danish letters?
A: Notice that you should have UTF8 charset on your page too:
<meta http-equiv="Content-Type" content="text/html" charset="UTF-8">
You can also use another charset on your html page and open your data file in text editor, enter thissymbols and save data file in the way you save your html page.
Notice that you should turn off "Tools/Use utf8 encode" setting inorder to open your data file correctly in Deluxe Tuner.
Q: I am considering ordering your product, but I have a few questions. My site uses frames, such that the submenus display in a different frame than the top level. Do all your dhtml menu templates support frames in this manner. I am specifically interested in the Ajax and Dynamic DHTML Menu.
Are your products licensed individually or does one license get access to Ajax, Dynamic, etc.? I understand the single, multi, and developer options.
A: See you can create JavaScript Tree Menu in cross-frame mode.
See more info about cross-frame mode here:
http://deluxe-menu.com/cross-frame-mode-sample.html
JavaScript Tree Menu has the following features:
Ajax support
Cross frame support
Dynamic Menu - Javascript API
Popup mode
and others.
> Are your products licensed individually or does one license get
> access to Ajax, Dynamic, etc.?
You should order the license for JavaScript Tree Menu only.
