Recent Questions Tree Based Javascript Rollover
Q: You've been helping me with some issues on the Javascript/DHTML Tree Menu system my company has purchased and most issues are resolved, so thank you! One big problem remains though and we can't seem to figure it out, so I hope you can help.
What we want is, when a user enters our site from the index (home) page then clicks on a link and the sub-page opens, for the dhtml menu tree to be open to the section the user is in and viewing. We also DO NOT want the browser to save the state of the menu, since that is inconsistent with where the user is in the site. Note: we do not use the Menu on the home page, is this a problem?
Per your tech support email, I've added the expand code, which works going from the home page to sub-pages. However, it interferes with navigating to other sub-pages once your in the site. The menu doesn't keep the section open, it closes back up. You mentioned the expand code has to be entered on every page....is that so in this instance and if so, that's a maintenance nightmare - does a better way exist for this type of menu?
Then we activated the "save state" option and the menu stays open on the sub-pages, but the expand option doesn't work.
It's like they cancel each other out and you can only have one or the other.
Can I get these two to work together? What do I need to do? Is it better to use the XP-style menu?
A: When user clicks the link, the browser loads a new page and the script re-create the dhtml menu tree.
If you want to open the needed section automatically on load you can use the following:
1. Save the state to cookies
2. Use frames
3. Put the special script on each page of site that will open appropriate section.

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'm interested in to buy the product of yours: deluxe-menu. But I've got a dude.
I've been working with the trial version, but I haven't been able to put HTML code within the javascript pop menu Item, in order to do actions like opening a new URL, or opening a file or page with .htm extension.
A: Actually you are able to paste any html code within items.
For example:
var menuItems = [
...
["||<nobr><FORM method=GET action='http://www.google.com/custom'><input name='as_q' value='search
the 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", "", "", "", "", "2", "", "", "",],
["test","testlink.html","",]
["<a href='testlink.html'> test </a>","","",]
