Q: Is there any way to call a javascript function on mouseover from a menu item?
A: You can use your own javascript functions in the menu items.
You should paste "javascript:some_function()" into item's link field, for example:
var menuItems = [
["text", "javascript:your_function(...)", ...]
];
var menuItems = [
["item text", "javascript:alert('Hello World')", , , , ,]
];
Unfortunately, you can't assign onmouseover/onClick event to each item. However, you can achieve this by using standard html objects within items, for example:
var menuitems = [
["<div onMouseover='your_code_here'>item text</div>", "index.html"]
];
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: I am using Deluxe-menu 3.0.
I can add dhtml popup menu items and submenu items. Each new sub menu item is placed at the bottom of that list. How can I move it up in the listing.
For instance if my menus are:
2007
2006
2005
2004
and I add 2008 - it will be placed below 2004, but I want it at the top of the list. Each item in the list has multiple subitems, so I don't want to delete the other items to get it in the correct order.
I looked through your help file, FAQ and online questions and could not find an answer.
A: To move items select items you want and use a mouse drag'n'drop method.
To copy dhtml popup menu items select those you want and use a mouse drag'n'drop method holding a Ctrl key.
You can find this info in Tuner's help, "Main Window" sheet.
Q: I am using cross frame menu dropdown. I have three frames: Top, Left and main (middle).
I am using the script and data from your sample file; it works fine. Only problem is submenu is offset to the right. It does not show up exactly down below the top menu.
What could be the problem?
A: JavaScript Tree Menu doesn't work correctly (incorrect submenu position) if youhave complex frame structure.
The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, so submenus drop down with an offset.
You should create, for example, the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine a width of the 1st column in the second row.
You should write init function in the following way in that case:
dm_initFrame("mainframe",1,3,0);
