Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: Is it possible to change from a default target setting for all links to _self target for onsite links and _blank target for offsite links?
A: You can set target parameter for each item.
See menuItems parameter:
var menuItems =
[
["Home","testlink.html","icon.gif","iconover.gif","Home Tip",target,"1"],
["|Our Products","testlink.html","icon1.gif","icon2.gif","Our Products Tip","_blank",,"0"],
];
Q: I have been evaluating your dhtml-tree product, for a potential use.
It does just about every thing I want apart from 1 thing:
I want each css dropdown menu item to (optionally) support the following syntax:
<a href="menu_link.html" onClick="return fnClickedLinked()">Menu Link</a>
I have worked out how to change the "menu_link.html", and also that it could be something like "javascript:fnClickedLinked()".
However I want the above syntax, where search engines can pick up the link and if my function returns false, the link is not followed when clicked.
Is this possible?
Or can I cancel the link navigation using the tree API node click event??
A: Actually you can add the html code inside item's text:
["|<a href="menu_link.html" onClick="return fnClickedLinked()">Menu Link</a>","", "", "", "", "Tip", "", "", "", "", ],
You can also try to use API function:
function dtreet_ext_userClick (itemID)
http://deluxe-tree.com/functions-info.htmlQ: I have heard from some page visitors, that they couldn’t see the menu. Could this be a problem with deactivated Java script or could you tell me some possibilities what it could be.
A: Your visitors should change security settings in IE to allow Javascript on pages they load.
When your security settings in IE doesn't allow Javascript onpages you load you can't see a dynamic page content.
There is no way to enable these preferences automatically, in othercase there are no reasons to create security preferences.
