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: I’m interested in adding cascading navigation bar to a website that was written in Microsoft Frontpage.
A: JavaScript Tree Menu wasn't developed as Dreamweaver/Frontpage/Yahoo SiteBuilder extension,
BUT you can use it as standard Javascript files. To install the menuinto your html page:
1. open the page in your program
2. open html source code of the page
3. add several rows of code (<script> tags).
For info see: http://deluxe-menu.com/installation-info.htmlQ: I have the dynamic dropdown menu working perfectly on the main page of the website, but when I try to install it onto html files that appear in subfolders of the site, the images do not appear. I have put ../ before all the links I can find and have the following codes placed in my file, what am I doing wrong?
A: You can use additional parameters to make dynamic dropdown menu paths absolute:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
These parameters allow to make images and links paths absolute.For example:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
var menuItems = [
["text", "index.html", "icon1.gif", "icon2.gif"],
];
So, link path will be look so:
http://domain.com/pages/index.html
Images paths will be look so:
http://domain.com/images/icon1.gif
http://domain.com/images/icon2.gif
Please, try to use these parameters.
Q: We have found that some of the menu /sub menu trees do not "collapse" when youclick on another item of the web tree view Do you have any suggestions as to what we can look at to correct the problem?
A: Check the following parameters:
var tcloseExpanded=1;
var tcloseExpandedXP=1;
