Recent Questions Rtl Tree Menu
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: Is there a javascript API for the expandable menu tree to fire an user click event so the browser will load proper page accordingly? I looked around the current APIs from your site and could not find one.
Please advise.
A: You can use dtreet_ext_userClick (itemID) function.

Actually you can use your own Javascript code instead standard links and html code inside item text. For example:
var tmenuItems = [
["text", "javascript:your_code_here"]
];
or
var tmenuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
Q: I activated option "state saving" but I think there's a problem;
when I open the website and click on an item of the menu, the pressed item becomes red
(up to now it's ok), but if I have topress F5 on the keyboard or press on the refresh button
to refresh the web page, the pressed item loses its color red.
I'd like the pressed item in the dhtml expand menu to maintain its color after the refresh command.
How can I solve this problem?
A: Tree Menu doesn't save a presseditem as it saves a tree state.
It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function apyt_ext_setPressedItem(menuInd, itemID)
<script type="text/javascript">
var i = 4 //index of the selected item
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
</script>
Q: If there was a way to show the links inside the html code instead of the dhtml menu js files. Shouldwe use an alternative mode as (css Style?)
A: You can move menuItems into html page directly inside <script> ...
</script> tags:
<script>
var menuItems [
...
];
dm_init();
</script>
You can also use search engine friendly code and install it on yourpage before you call your dhtml menu js file.
You'll see text links in that case.
To create a search engine friendly menu you should add additional html code within your html page:
<div id="dmlinks">
<a href="http://deluxe-menu.com">menu_item_text1</a>
<a href="http://deluxe-tree.com">menu_item_text2</a>
...etc.
</div>
To generate such a code use Deluxe Tuner application.
Run Tuner, load your menu and click Tools/Generate SE-friendly Code (F3)
