Recent Questions Javascript Tree Control
Q: I have some problems with Javascript/DHTML Tree.
I have set the var tlevelDX to 5 to decrease the indent for each level of items, but would like to decrease the indent even more. Ican't find the parameter that will set the indent in pixels of thefirst level item.
Also, is there a setting that will put text for a menu item on a second line?
I hope that you can help.
A: You can make the smallest indent this way:
var tlevelDX = 0;
You are not able to have more little indent. This place is reservedfor + buttons.
Try to set this parameter:
var tnoWrap=0;
You can also use <br> tags in the item text, for example:
var tmenuItems = [
["line 1<br>line 2"],
];
Q: If I wanted to change the graphics at a later date in tab menu javascript (main top tabs, subtabs, etc.), how would I do that?
A: In that case you should open images I'm using for top tabs in any graph editor and changethem.
back.gif
back_o.gif //back images for normal and hover states for the last tabs in the top menu(instead of the 1-st 6 items)
sep_top.gif // separator for the top items
top1.gif
top1_o.gif //back images for normal and hover states for the 1-st tab, you can change thetext of this tab in deluxe-menu.js:
["<font color='#FFF90E'>MAIN</font><br>Initiative<br>(Strategy)","testlink.html", "", "", "", "", "5", "4", "", "", "", ],
By the way to apply hint for this item you should write:
["<font color='#FFF90E'>MAIN</font><br>Initiative<br>(Strategy)","testlink.html", "", "", "This hint appears when you hover over the 1-st item", "", "5", "4", "", "", "", ],
top2.gif
top2_o.gif //back images for normal and hover states for the 2-nd tab, you can change thetext of this tab in deluxe-menu.js:
["<font color='#FFF90E'>PAIN</font><br>Identified<br>(Problems)","", "", "", "", "", "6", "", "", "", "", ],
and so on...
For the subtabs I'm use images for arrows only:
var arrowWidthSub=8;
var arrowHeightSub=8;
var arrowImageSub=["deluxe-menu.files/arrow.gif","deluxe-menu.files/arrow_o.gif"]
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 want to use
function dtreet_ext_userRightClick(itemID) {
alert(itemID[0]); ???
return false;
}
But how do I refer to tmenuItems array using itemID in the javascript?
For example, if I want to pop a link text, should I use alert(itemID[0]))?
It doesn't work.
Please let me know how I refer to the menu.
A: You should use the following function to get item's info:
dtreet_ext_getItemParams (0, itemID);
For example:
<script type="text/javascript">
function dtreet_ext_userRightClick(itemID)
{ var link = [];
link = dtreet_ext_getItemParams (0, itemID);
//Returns item parameters in the array:
// [item_id, index_within_submenu, parentID, level, has_child, child_count, expanded, text, link, target, tip, align, icons, hidden, disabled, visible]
alert(link[7]);
return false;
}
</script>
