Recent Questions Javascript Dynamic Tree
Q: Hello, I am interesting in purchasing your product, but first I need to know if it is possible to call a JavaScript function from the menu. I have read the FAQ and noted where it lists that you can perform an alert call, and that worked on my end as well, but when I attempted to call a function I created I could not get it to respond. Is it possible to call a function from your menu? Could I get an example?
A: You can write your own functions within menuItems, for example:
["|Real-Time Data Query","javascript:window.open('http://www.domain.org/', '_blank','height=758,width=1024,status=yes,toolbar=no, menubar=no,location=no');",,,'Query real time water quality data' ,'' , '', '', ,],
Q: Pls help me with another question.
I have an horizontal menu in which the submenus drop down (as in example # 1 you have in your web).
For the first level items (which are horizontal), I do not want item spacing or itemPadding, that is:
var itemSpacing=0;
var itemPadding=0;
However, for the second and third level menu items, that drop down, I do need spacing and padding, like this:
var itemSpacing=1;
var itemPadding=1;
How can achieve this if, we have only one set of parameters??
Thank you very much and best regards
A: You should use Individual Styles.
You should set the following parameters:
var itemSpacing = 0;
var itemPadding = 0;
and create individual style for submenus
var menuStyles = [
["menuBackImage=images/subm_back.gif","itemSpacing=1","itemPadding=1"], // add Spacing and Padding to the style which is used for the third level menu items.
["columnPerSubmenu=2"],
["itemSpacing=1","itemPadding=1"], //style 2
];
You should assign this style for the second and third level menu items

Q: When i stay on one page so must have the menue-point of the html menu for this page another color or font. How can i make this?
A: You should set pressed item.
Please, check the following parameter
var pressedItem=-2;
This parameter sets an index of an item that will be highlighted by default.
-2 - the toggle mode is disabled;
-1 - the toggle mode is enabled, but no items highlighted by default;
0,1,2,3,... - index of highlighted item in a top-menu.
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.
You can also set the correct
var pressedItem=1;
parameter on each html page.
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:
http://deluxe-menu.com/rq-loading-bar-MySQL-support.html
This example is not for Javascript/DHTML Tree menu, but you can create your menu in the same way.
