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: With menu tabs, I'm trying to dynamically set the bselectedItem parm, using php. If I set bselectedItem to anything other than 0, the submenu goes away and the main html tab javascript is not highlighted.
If I set to 0, everything works.
A: See, if you use Tab Mode
var tabMode = 1;
var bselectedItem = 0; //main items
var bselectedSmItem = -1; //submenus
So you should set:
var bselectedItem = 0; //main items (0;7;14;21;25)
var bselectedSmItem = -1; //submenus (1;2;3;4;5....)
Q: One other issue I'm having is that the content for the menu bar in java "selected tab" on my site does not show up in IE7. Works fine in firefox, though. Any ideas about that?
A: Try to delete height: 0%; parameter from the styles:
<div id="content1" style="height: 0%; visibility: hidden;" class="tabPage">
So you'll have:
<div id="content1" style="visibility: hidden;" class="tabPage">
Q: I want to run a javascript function when a user clicks on item in the dhtml pop up menu,
How can I do this in the data file?
A: You can use your own Javascript code instead standard links. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
