Recent Questions Drag And Drop Javascript Sharepoint Treeview
Q: I downloaded the free trial version and so far it looks like we can do everything. I have a couple questions:
the designer wants it so that when any of the submenu choice are selected, the main main menu in java item should be highlighted when the submenu page is displayed (kind of a breadcrumb). So, is there any way to change the background image of one of the main menu items after the menu loads? I haven't tried running my main menu in java in a webpage yet so I'm not sure if you generate a separate CSS file or put all of the settings into a STYLE= attribute of each tag.
A: The main menu in java 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, forexample:
<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.
Q: I want tree view menu to be in expande state mode, how can I do this? Also, same goes for all the other menus depending which link I click.
A: You can try to to call the following function/functions to expand/highlight items, for example:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>

2. In internet explorer, when you mouse over Need An Expert?, Technology the first time you go to the page, there is a 3-4 second delay before the submenu opens. There are a lot of submenu items under Technology, but in Firefox, there doesn't seem to be this delay. Do you know why this would happen in IE? Is there a way to fix it? Could the problem be that each submenu item has a background graphic and this is causing the delay?
3. When you get to a page on the site and you rollover the top level menu, there is also a delay before the background image of the menu items shows up. You get a solid blue background color for a second or two (the bgcolor assigned) and then the graphic loads and shows up. Is there any way around this? I have a javascript to preload the image (back.jpg) but that doesn't seem to help.
Any help would be greatly appreciated!!!
A: 1. The scroll speed depends on number of items to be scrolled, more items -> faster scroll.
You can decrease the number of items or enlarge the size of submenu.
2,3. Please try to add the following param:
var dm_writeAll = 1;
It will load all backgrounds on page load, no on mouseover.
Q: Is it possible to have the AJAX menu aligned vertical instead of horizontal? And is the number of levels limited? (I have a site that requires up to 4 levels...)
A: Yes, you can create vertical menu using AJAX feature.
There is no such limitation.
See the following parameter:
var dmAJAXCount=0;
That variable set the maximal number of submenus that will be loadedfrom server on your page.
