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: Can you please give me an example of how I would return the full path to the selected item of the web site menu?
A: See the following example:
function getFullPath(mInd){
var result='';
// get pressed item
var params = dm_ext_getMenuParams(mInd);
if (!(params[2]>=0)) return '';
function getPathForItem(mInd,smInd,itInd){
// get for this item
var params = dm_ext_getItemParams(mInd,smInd,itInd);
var result = params[2]+ '('+ params[3]+')';
// find root item id
if (smInd <= 0) return result;
params = dm_ext_getSubmenuParams(mInd,smInd);
for ( var smInd_=0;smInd_ for ( var itInd_=0;itInd_ itParam = dm_ext_getItemParams(mInd,smInd_,itInd_);
if (itParam[0]=arams[2])// id
return result + '->' + getPathForItem(mInd,smInd_,itInd_);
}
}
return result;
};
return getPathForItem(mInd,params[1],params[2]);
}
Q: The only remaining problem I see is that the html popup menu appears in slightly different positions depending upon where your mouse touches the icon.
Is there a way to make the menu position absolute in respect to the icon? I have tried playing with the menu item parameters that seemed related with no success.
A: See dm_popup() function parameters:
return dm_popup(menuInd, pause, event, x, y)
menuInd - index of the menu on a page, >= 0.
pause - determines the time when the html popup menu will be hidden.
event - constant. Do not change.
x, y - optional. Set these parameters if you want the menu to appear in the specified place.
In other case the menu will be shown in the mouse position.
Q: I use menu with color graphic buttons, I believe the color buttons locate in @BOOK1\@Test_BOOK1.files.
At this directory level(please look in Book1.zip), the display is OK,
However, if I click on "06) Introduction.to.Small-Signal.Amplifiers\<>>(06_IT.htm)" to move to the next level, the color buttons will not display properly.
Can I set pointer that tells file 06_IT.htm that I have "@Test_BOOK1.files" in "@BOOK1" folder?
A: You can use additional parameters to make menu paths absolute:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
These parameters allow to make images and links paths absolute.
For example:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
var menuItems = [
["text", "index.html", "icon1.gif", "icon2.gif"],
];
So, link path will be look so:
http://domain.com/pages/index.html
Images paths will be look so:
http://domain.com/images/icon1.gif
http://domain.com/images/icon2.gif
Please, try to use these parameters.
