Recent Questions Walker Javascript Tree
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: Only problem left is that we see an empty image in the left corner of the java pulldown menu.
I can't find how to remove this image. Do you know where this comes from?
A: You should delete the following string from your menuItems
["","", , , , , "0", ],
Try that.
Q: I have tested and tested but can't find out how I can add the following, as a link in drop down navigation bar. Can you please help?
http://domain.no/secure/modules/tutorials/cpanel-x3/cpanel-x3-addon.swf" rel="shadowbox;height=450;width=780"
A: You should add <a> tag into the text field in that case:
["<a href="http://domain.no/secure/modules/tutorials/cpanel-x3/cpanel-x3-addon.swf" rel="shadowbox;height=450;width=780">test</a>","",""]
But you should specify a styles for this link also.Q: We are wanting to make this collapsible menu Dynamic by reading from a Microsoft SQL Data base.What is the approach in accomplishing this?
A: 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.:
<noscript><a href="http://deluxe-tree.com">Javascript Tree Menu by Deluxe-Tree.com</a></noscript>
<script type="text/javascript" src="menudir/dtree.js"></script>
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var tmenuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
The example of the menu working with PHP/MYSQL you can find here:

This example is not for Javascript/DHTML Tree menu, but you can create your menu in the same way.
