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: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: Tell us javascript code to select or highlight the tab and sub tab in javascript tabs navigation.
A: Deluxe Tabs doesn't support API functions which can return theselected tab.
You can set "bselectedItem" and " var bselectedSmItem" parametersbased on your link before you call your data file.
For example, move " var bselectedItem" and " var bselectedSmItem" parametersfrom your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=<?php echo $seltabs; ?>;
var bselectedSmItem=<?php echo $selsmtabs; ?>;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
You should define seltabs and selsmtabs using server side script.
You can also set it on every page before you call data.js file, forexample:
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=4;
var bselectedSmItem=3;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
Q: Where can I give the body of the javascript method which I use in cool dhtml menu?
A: You can define functions after menuItems, before you call dm_init();function.
var menuItems = [
["text", "javascript:your_function(...)", ...]
];
Where your_function(...):
function your_function(...)
{
.....
}
