Q: What can I do to optimize the load time for dhtml rollover
and prevent reloading it from the server with every page reload.
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: In IE7 I see the deluxe-menu.com link on the top and no javascript navigation menu on my page.
A: Your browser has JavaScript option disabled.
It means that no one JavaScript element can be run.
You should to enable JavaScript in IE:
Tools -> Internet Options -> Security -> Custom level... -> Scripting -> Active Scripting = Enable
There is no way to enable these preferences automatically, in other
case there are no reasons to create security preferences.
You can use search engine friendly code, so you'll see all your
links (for the main items and submenus) when your security settings in IE doesn't allow Javascript.
You can generate search engine friendly code.
JavaScript Tree Menu is a search engine friendly menu since v1.12.
To create a search engine friendly menu you should add additional html code within your html page:
<div id="dmlinks">
<a href="menu_link1">menu_item_text1</a>
<a href="menu_link2">menu_item_text2</a&tg;
...etc.
</div>
To generate such a code use Deluxe Tuner application.
You can find this GUI in the trial package.
Run Tuner, load your menu and click Tools/Generate SE-friendly Code (F3).
Q: Is there any way to keep a menu lit up when going to another page? Or do the menus always have to default back to their normal state?
I want the menu to know what page the user is on and keep that section highlighted. Any ideas?
A: You should 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.
Q: I have noticed an issue with the menu. Dhtml pop up menu does not drop down over the frame if a pdf is being displayed. It does something weird to the browser like shortens the main frame and displays above the menu.
A: Notice that you should add your pdf inside IFRAME tag.
Try to set the following parameter to overlap .pdf files:
var useIFRAME=1;
