Q: I have read your http://deluxe-tree.com/whats-new-info.html.
And really I do not understand this phrase:
- Item ID format has changed. It depends on the parent ID = [parent ID]i[item index].
Examples: for the first level dtree _0i0, dtree_0i1..., for the second level dtree_0i1i0,dtree_0i1i1, dtree_0i1i2...
Where do I fill in?
Do I have to rename my cascading menu titles?
A: Actually you shouldn't change anything.
This info is for the customers who use these indexes (dtree_0i1i2) only.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 way we can add javascript behaviors to the sliding dhtml menu actions?
For example, is there a way we can add an onClick function to a menu item
(eg,onClick="return MyFunction( )" ) so that we can catch and process key events?
A: Unfortunately, you can't assign onmouseover/onClick/onContextMenu event to each item.
However, you can achieve this by using standard html objects within items, for example:
var menuitems = [
["item text
", ""]
];
You can use your own Javascript code instead standard links. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
Try that.Q: I've been trying to get the menu item in dynamic tree menu to stay highlighted when clicked on and directed to that page.
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));
}
To expand specific items you should use the following function:
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 11), 1);
