Q: I try to use the javascript menu popups to show an image; then when the mouse is over the image I dynamically generate a panel of http links. It works perfectly, but the problem is that I would like to do the same with several images (for instance 2) and different links : I'm not able to do that, whether I change the value of menuItems var or not, I display the same link values on both images (it seems menuItems is a global var and can be set only once).
Have you heard about this problem and could you give me a solution (this is a bit urgent, I have sold this solution to my customers) ?
A: See how you should call dm_popup() functions:
<img src="../../../../fileadmin/img/flag_de.gif" width="50" onMouseOver="return dm_popup(0, 2000, event);" style="cursor: pointer;">
// 0 - is ID of the first menu
....
<img src="../../../../fileadmin/img/flag_fr.gif" width="50" onMouseOver="return dm_popup(1, 2000, event);" style="cursor: pointer;">
// 1 - is ID of the second menu
// 2 - is ID of the third menu
... and so on.
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 need to know if it is possible to call a JavaScript function from the cool dhtml 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 Iattempted to call a function I created I could not get it torespond.
Is it possible to call a function from your menu?
Could Iget 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: Hi - I've turned on tsavestate which works, but it acts erratically. I have my javascript cascade menu .js file in a /js folder, and the site has multiple directories, but all the pages in all directories use the same menu SSI include, which uses the same deluxemenu code in the common /js folder. I read your KB article about states, cookies and multiple folders, but it is confusing... does it actually save state per directory, versus per the entire domain? I only have one menu for the entire site.. just would like it to save state correctly for all pages in all folders that include that javascript cascade menu.
A: It's a feature of the browser. It creates different cookies for eachsubdirectory.The only way is to place all your pages in the one directory.
