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: We are registered users of the Deluxe Menu software. Today I tried to use the Javascript API, but there is something I do not understand and want to ask for support.
First, I set up a very simple menu:
var menuItems=[
['Menu 1'],
['|Submenu 1'],
['Menu 2'],
['|Submenu 2'],
];
This menu is built via dm_init().
Then, I inspect the menu (in Firebug):
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
Ok, there are three submenus. Now I am going to delete one of them:
>>> dm_ext_deleteItem(0, 0, 1)
"Menu 2" disappears on the screen, this works as expected. But now when I re-inspect the menu using the API, I find that the API reports exactly the same as before:
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
So, it seems the report function continues to know about the original menu structure and reflects it. Am I using the API in a wrong way?
The problem I want to solve is to remove the entire menu dinamico dhtml, in order to rebuild it dynamically. Because I did not see a function aimed to this functionality, my plan was to delete all main menu entries subsequently until the main menu inspector no longer reports an entry. Is there (a better) way to achieve this?
A: Unfortunately, dm_ext_deleteItem() only change visibility of theseitems.
It doesn't delete them completely.
We'll try to fix it in the next versions of Deluxe Menu.
Q: Can I install the menu using my buttons? I might be able to do it if the buttons used only one image, but they use two images. One is light and the other dark.
I also have some questions:
1) Will the menu stay in view when the user scrolls down?
2) I'm not even sure I care if the menu stays in view, because I believe that is done using php and is not good for SEO. The file that the search engines see is index.html while the file that visitors see is home.php. I think it would be better for SEO to have a normal .html page. Are you able to do that?
A: See how you should make image-based menus: if item text is empty, icon fields will be used as item images.
For example:
["", "index.html", "menu1a.gif", "menu1b.gif", "Home Page"]
1) You should use floatable feature.
See the following parameter:
var floatable=1;
2) You can generate search engine friendly code using Deluxe Tuner:
"Tools/Generate SE-friendly Code".
Q: Can I use javascript to get the object (getElementByID). If not howdo I hide my dropdown menu on print?
A: You can add a new button to print your page and call onClick event, soyou should write:
<body ....
onClick="document.getElementById('dm0m0').style.visibility='hidden'; window.print();">
...
</body>
Or you can use the same javascript code from your menu item.
For example:
var menuItems = [
["Print", "javascript:document.getElementById('dm0m0').style.visibility='hidden';
window.print();", icon1, icon2],
];
But if you want to hide the menu when your customers push "File/Print"you should write so:
You must create two functions, for example:
function myprint()
{ document.getElementById('dm0m0').style.visibility='hidden';
window.print();
}
function myprint2()
{ document.getElementById('dm0m0').style.visibility='visible';
window.print();
}
You should add this functions into your code.
And then you must write so:
window.onbeforeprint = myprint;
window.onafterprint = myprint2;
