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: I know. I have two menus on the page and I am not using beforeItemImage orafterItemImage for the top menu in javascript (the one you referenced below), but I need it for the second menu. The parameters for that menu are in mainnav_data.js.
Even when I only call dmWorkPath and dmenu.js once, it does not work.
A: See, it is not correctly to use image-based items:
["","", "mainnav_data.files/corpinfo.gif", "mainnav_data.files/corpinfo2.gif", "", "_self", "0", "", "", "", "", ],
and specify beforeItemImage/afterItemImage parameters. They won't work in that case.
You can create such buttons in the following ways:
1) Use image-based menu (images with text).
Create normal and mouse-over state images (with text) for each item:
["","", "mainnav_data.files/corpinfo.gif", "mainnav_data.files/corpinfo2.gif", "", "_self", "", "", "", "", "", ],
["","", "mainnav_data.files/new.gif", "mainnav_data.files/new2.gif", "", "_self", "", "", "", "", "", ],
["","", "mainnav_data.files/xxxxx.gif", "mainnav_data.files/xxxxx2.gif", "", "_self", "", "", "", "", "", ],
2) Use combined background for the menu in javascript items (images without text).
var beforeItemImage = [,]; //left-side image for normal and mouse over state
var itemBackImage = [,]; //background or image for normal and mouse over state
var afterItemImage = [,]; //right-side image for normal and mouse over state
var beforeItemImageW = '';
var afterItemImageW = '';
var beforeItemImageH = '';
var afterItemImageH ='';
But you should create a small images in any Graph Editor, for example:
button_n_back.gif
button_n_left.gif
button_n_right.gif
button_o_back.gif
button_o_left.gif
button_o_right.gif
You cannot use these two methods together!
Q: We are experimenting with your library but can't seem to make it work. I am getting "d_ddm is undefined" in dmenu_popup.js menu script.
Could you tell me what we are doing wrong?
A: You should change
onClick="return dm_popup(1, 500, event);
to
onClick="return dm_popup(0, 500, event);
If you have only one menu on the page your menuInd = 0;
Q: How do your users normally indicate which page a web visitor is on, by using your navigation bar submenu?
A: Deluxe Menu has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, for
example:
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<script type="text/javascript"> var pressedItem=3;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
