Recent Questions How To Make Tree Jscript
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: How can I manage that the last clicked javascript expanding tree item stays tree highlighted?
A: We have the following API function to highlight the pressed item in Javascript/DHTML Tree
function dtreet_ext_setPressedItem (menuInd, itemID)
But unfortunately this function doesn't work for AJAX submenus.
We'll try to add this feature soon (using save state feature).
Q: 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.
Q: Could you please tell me, wether it is possible to place the arrows in the front of the javascript web menu items instead of after. I am working on a Vista menu.
A: Try to use the following javascript web menu parameter:
var dmRTL=1;
