Q: Is it possible to show a menu item in the simple navigation bar as selected by default to indicate what the current page is?
A: The menu has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, forexample:
<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>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also 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.
Q: I’d like to know how to populate the navigation bar menu from a database?
A: 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 = [
// Write Javascript code for menu items
echo getMenuItems();
?>
];
</script>
Q: I would like to know how to put the items for the popup menu on multiple lines (i.e. create a line feed), how do I tell my code to start a new menu item on the NEXT line?
A: There are 2 ways to do that:
1. set
var noWrap=0;
2. use
tags, for example:
var menuItems = [
["|Here is where <br> I would like
to have a line<br> feed",,"","", "", "", "", "", "", "", "",],
];
Q: How I make to insert a code java in the event on click of the button "Ok", when this button is simple tree view?
A: You are able to paste any html code within items.
For example:
var tmenuItems = [
...
["<nobr><FORM method=GET action='http://www.google.com/custom'>
<nput name='as_q' value='searchthe web' size=15 style='font-size:10'> <INPUT type=hidden name=cof
value='LW:144;L:http://domain.edu/images/sulogo.gif;LH:45;AH:center;GL:0;S:http://domain.edu;AWFID:e01cb67b8afe383e;'></form></nobr>","",
"images/icons/search.gif", "", "", "", "", "", "", "", "",],
You should write your own code within tmenuItem.
