Recent Questions Javascript Tree In Relationships
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 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: May I can use PHP code in menu items of my dhtml website navigation menu?
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.:
<!-- JavaScript Tree Menu -->
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<!-- (c) 2006, 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: Under Parameters ->> Dimensions ->menuWidth
Even I change the value such as 150px it doesn't have any effect on javascript dhtml menu itself.
Changing menuHeight property such as menuHeight = 123px moves menu down from the top of the page instead of changing height of the menu itself.
I used templates ->> vista -> vista style 3-03 to generate the javascript dhtml menu and modified it.
A: See, you have itemWidth and itemHeight in the Individual Style.
var itemStyles = [
["itemWidth=94px","itemHeight=23px","itemBackColor=transparent,transparent","itemBorderWidth=0", "fontStyle=bold 10px Tahoma","fontColor=#FFFFFF,#FFFFFF", "itemBackImage=data-vista-3-03.files/btn_cyan.gif,data-vista-3-03.files/btn_cyan2.gif"],
];
You cannot set the less value for the menuwidth in that case. You canset only the bigger value:
var menuWidth="550px";
To change the menuHeight you should also use itemHeight parameter, forexample
itemHeight=123px
