Q: I am having some difficulty dynamically adding items to a dhtml sliding menus.
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item
(notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in the
specific place, for example set itemInd=5 if you want to add item
before the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: I have implemented a deluxe-menu on my client's website and I had a couple of questions.
1. Can I control how fast the submenus scroll in my javascript menu examples? If you look at the site and hover over Need An Expert? on the menu and then point to Practice Areas, this submenu seems to scroll slower than if you mouse over "Technology" and scroll that submenu. The Technology submenu scrolls a lot faster. Is it because there are many more items in the Technology submenu? I tried to find a setting for "scroll speed" or the like, but I couldn't find it.
2. In internet explorer, when you mouse over Need An Expert?, Technology the first time you go to the page, there is a 3-4 second delay before the submenu opens. There are a lot of submenu items under Technology, but in Firefox, there doesn't seem to be this delay. Do you know why this would happen in IE? Is there a way to fix it? Could the problem be that each submenu item has a background graphic and this is causing the delay?
3. When you get to a page on the site and you rollover the top level menu, there is also a delay before the background image of the menu items shows up. You get a solid blue background color for a second or two (the bgcolor assigned) and then the graphic loads and shows up. Is there any way around this? I have a javascript to preload the image (back.jpg) but that doesn't seem to help.
Any help would be greatly appreciated!!!
A: 1. The scroll speed depends on number of items to be scrolled, more items -> faster scroll.
You can decrease the number of items or enlarge the size of submenu.
2,3. Please try to add the following param:
var dm_writeAll = 1;
It will load all backgrounds on page load, no on mouseover.
Q: Do I need any additional loaded software as a visitor to a webplace using the Deluxmenu, for example Java applet, flash etc.?
A: You don't have to install additional software.
Your customer should change security settings in IE to allow Javascript on pages he loads.
When your security settings in IE doesn't allow Javascript onpages you load you can't see a dynamic page content.
There is no way to enable these preferences automatically, in othercase there are no reasons to create security preferences.
Q: I need to work it with PHP/MySQL. I have found some information on it in your Support section, but have problems to understand and wonder if you have more information or a working sample of the loading bar with PHP/ MySQL.
A: Info about generating menu (menu items )from a database, please, see:
http://deluxe-menu.com/generate-menu-from-database-xml-php-asp-vb-support.html
Please, see the example of .php file.
The content of .php file depends on your database structure.
<?php
// The example for PHP/MySQL.
// MySQL database has the table "menuTable" that contains data for menu items.
// The table has the following fields:
// 1. "text" - item text
// 2. "link" - item link
// 3. "icon1" - item icon (normal state)
// 4. "icon2" - item icon (mouseover state)
function getMenuItems()
{
$jsItems = '';
// Select all records from table "menuTable"
$allItems = mysql_query('SELECT * FROM menuTable;');
// Extract items data from database and build Javascript code for menuItems
while ($itemData=mysql_fetch_array($allItems))
{
$jsItems .= '["'.$itemData['text'].'", "'.$itemData['link'].'", "'.$itemData['icon1'].'", "'.$itemData['icon2'].'"],';
}
// Return Javascript code
return $jsItems;
}
?>
<script>
var menuParam1 = value1;
var menuParam2 = value2;
var menuParam2 = value2;
...
var menuItems = [
<?php
// Write Javascript code for menu items
echo getMenuItems();
?>
];
</script>
